The city of Mumbai has an existing international airport, the Chhatrapati Shivaji Maharaj International Airport
(CSMIA), operated by Mumbai International Airport Limited (MIAL). CSMIA’s landside and airside expansion
constraints created the need for second airport to serve the Mumbai Metropolitan Region (MMR).
The City and Industrial Development Corporation of Maharashtra Ltd. (CIDCO), undertook the global bidding
process as the nodal agency, to develop a new greenfield airport known as the Navi Mumbai International Airport
(NMIA) under a Public Private Partnership (PPP) framework on a Design, Build, Finance, Operate and Transfer
(DBFOT) basis, for a 30 years concession period, extendable by another 10 years. Thereafter, the concession can
be further extended for another 20 years through participation in an international competitive bidding process.
MIAL won the bid for development of NMIA. On October 25, 2017, CIDCO issued the Letter of Award (LoA) to
MIAL. Thereafter, Navi Mumbai International Airport Private Limited (NMIAL), was established for development,
construction, operation and maintenance of the greenfield international airport project at Navi Mumbai,
Maharashtra. NMIAL is a special purpose vehicle (SPV) owned by MIAL (74% shareholding) and CIDCO (26%
Shareholding). NMIAL signed the Concession Agreement with CIDCO on January 8, 2018.
NMIA is categorized as a Major Airport in accordance with the provisions of the AERA Act, 2008 read with AERA
(Amendment) Act, 2019 and 2021, as it is designed to operate with designated capacity of more than 3.5 MPPA as
stipulated under Annex-II to Schedule A of the Concession Agreement executed between NMIAL and CIDCO.
As per the provisions of the AERA Act 2008, NMIAL has submitted their Multi Year Tariff Proposal (MYTP) for
the First Control Period from April 1, 2025, to March 31, 2030. In adherence to the regulatory requirements, NMIAL
initially submitted MYTP for aeronautical tariff determination for the First Control Period on February 7, 2025,
with commencement date as May 31, 2025.
However, due to delays, NMIAL in their email dated September 22, 2025, communicated the intention to open the
airport for commercial operations by mid to end of November 30, 2025. Further NMIAL in their email dated
November 21, 2025, indicated that the tentative start for commercial operations for NMIA is December 25, 2025.
Since, the operations have commenced from December 25, 2025, the Authority proposes to revise the COD from
May 31, 2025 to December 25, 2025. With the revised COD being December 25, 2025, the Authority proposes to
consider the First Control Period as April 1, 2025, to March 31, 2030.
The Authority, after considering all the information currently available and further analysing the MYTP of the
Airport Operator and the views of Independent and Capex Consultant appointed by the Authority, has undertaken
the necessary adjustments in all regulatory building blocks. However, these adjustments would be finalized only
after consideration of the comments from the stakeholders.
The Authority has released this Consultation Paper, putting forward its proposals in the background of Authority’s
analysis and observations on the MYTP submitted by the Airport Operator.
The Authority shall consider written evidence-based feedback, comments and suggestions from all stakeholders on
the proposals made in the Consultation Paper and pass a suitable order determining the Tariff for aeronautical
services. The Authority would like to emphasize that the consultation process timelines are sacrosanct and hereby
requests the stakeholders to provide their comments/ input within the timelines specified in this Consultation Paper,
beyond which the same will not be considered by the Authority.
Consultation Paper No. 08/2025-26 Page 2 of 202The Authority has released this Consultation Paper, after considering various assumptions stipulated in the MYTP
submitted by NMIAL in respect of NMIA. Accordingly, the Authority’s proposals on the various aspects of the
Tariff determination process have been explained in detail in this Consultation Paper.
As per the provisions of Section 13(2) of the AERA Act, 2008, the tariff determination under the Tariff Order can
be reviewed and revised.
Thus, in accordance with the provisions of Section 13(4) of the AERA Act, 2008, the written comments on
Consultation Paper No. 08/2025-26 dated 17th March 2026 are invited from the Stakeholders, preferably in

1. BACKGROUND
1.1 Introduction
1.1.1 Navi Mumbai International Airport (NMIA) (IATA: NMI, ICAO: VANM) has been developed to cater
to the aviation requirements of the Mumbai Metropolitan Region (MMR) and is intended to serve both
domestic and international passengers as well as cargo.
1.1.2 The MMR is presently served by Chhatrapati Shivaji Maharaj International Airport (CSMIA), which is
operated by Mumbai International Airport Limited (MIAL). However, owing to its location within the
city limits of Mumbai, CSMIA faces physical constraints on capacity expansion, as outlined below:
a) Airside constraints: CSMIA operates two intersecting runways, which do not permit
simultaneous take-offs and landings, thereby limiting aircraft movement capacity per hour.
b) Landside constraints: CSMIA has a designated passenger handling capacity of 55 million
Passengers Per Annum (MPPA), comprising Terminal 1 with a capacity of 15 MPPA and
Terminal 2 with a capacity of 40 MPPA. The airport recorded passenger traffic of 55.12 MPPA
during FY 2024-25.
1.1.3 In view of the airside and landside constraints at CSMIA arising from its location in a congested urban
area, and to meet the growing aviation demand of the MMR, the Government of India (GoI) vide letter
no. AV24011/1/95-VB (Vol. VI) dated July 6, 2007, accorded approval for the development of a new
international greenfield airport at Navi Mumbai through Public Private Partnership (PPP) mode (“the
project”).
1.1.4 Pursuant to GoI approval, the Government of Maharashtra (GoM) vide its Government Resolution No.
CID-3307/1541/Pra. Kra-144/07/Na Vi-10 dated. July 30, 2008, approved the implementation of the
project and appointed the City and Industrial Development Corporation of Maharashtra Ltd. (CIDCO)
as the nodal agency for the purposes of the construction, operations and maintenance of the project.
1.1.5 In view of the GoI approval, GoM approval and other applicable permits, CIDCO, the nodal agency,
while prescribing the technical and commercial terms and conditions for construction, operation and
maintenance of the airport on Design, Build, Finance, Operate and Transfer (“DBFOT”) basis, invited
application by its Request for Qualification (RFQ) No. CIDCO/T&C/NMIA/01/2013-14 dated
February 5, 2014. Pursuant to the RFQ and based on technical, financial and operation and maintenance
criteria set out in the RFQ, and the receipt of the security clearance from the Ministry of Home Affairs
(MHA), GoI, applicants were pre-qualified to participate in the next stage of the bidding process.
CIDCO then called upon qualified bidders to provide their commercial bid in accordance with terms
and conditions prescribed in the Request for Proposal (RFP) issued by the letter No.
CIDCO/T&C/NMIA/01/2013-14 dated May 4, 2016.
1.1.6 Following the evaluation of the bids received, CIDCO accepted the bid submitted by MIAL and issued
its Letter of Award (LoA) bearing No. CIDCO/MD/NMIA/051 dated October 25, 2017, for execution

second airport to serve the MMR, NMIA is strategically located between the 8-lane Amra Marg (west)
and 4-lane NH-4B (east) in Navi Mumbai. The airport is also connected to the Mumbai Pune
Expressway (Sion-Panvel Highway) by Amra Marg. The Airport is also proposed to be accessible from
the existing Mankhurd-Belapur-Panvel commuter rail corridor from Khandeshwar Railway Station, and
from the Targhar Railway Station on the Nerul-Uran Railway line. The recently commissioned Mumbai
Trans Harbour Link (MTHL), a 22 km long bridge, across the Thane creek from Sewri to Ulwe, now
directly connects NMIA to South Mumbai.
1.2.8 The project site had challenging topography, including hills in and around the site, river and utilities
passing through the site. As per CA, Annexure to Schedule B- Pre-development Works, considering the
site topography, several site development works had to be undertaken by CIDCO to enable subsequent
construction of the airport project. These site development works to be undertaken by CIDCO were
termed as pre-development works and included the following:
a) Cutting of hills in and around the site (including Ulwe hill) up to 8 m above mean sea level and
filling of site up to 5.50 m above mean sea level;
b) Ground improvement works
c) Construction of sea wall /retaining wall along the boundary of the site
d) Shifting /relocation of utilities

Consultation Paper No. 08/2025-26 Page 27 of 202METHODOLOGY OF TARIFF DETERMINATION OF NAVI MUMBAI INTERNATIONAL AIRPORT
2. METHODOLOGY OF TARIFF DETERMINATION OF NAVI MUMBAI
INTERNATIONAL AIRPORT
2.1 Tariff Setting Principles
2.1.1 AERA was established by the GoI vide notification No. GSR 317(E) dated May 12, 2009. The functions
of AERA, in respect of major airports, are specified in section 13(1) of The Airports Economic
Regulatory Authority of India Act, 2008 (‘AERA Act’ or ‘the Act’) which are as below:
a) To determine the tariff for aeronautical services taking into consideration –
(i) the CAPEX incurred and timely investment in the improvement of airport facilities.
(ii) the service provided, its quality and other relevant factors
(iii) the cost for improving efficiency.
(iv) economic and viable operation of major airports
(v) revenue received from services other than the aeronautical services
(vi) the concession offered by the Central Government in any agreement or MoU or otherwise;
and
(vii) any other factor which may be relevant for the purpose of this Act:
Provided that different tariff structures may be determined for different airports having regard
to all or any of the above considerations specified at sub-clauses (i) to (vii)
b) To determine the amount of the development fees in respect of major airports.
c) To determine the amount of the passenger service fee levied under Rule 88 of the Aircraft
Rules, 1937 made under the Aircraft Act, 1934.
d) To monitor the set performance standards relating to quality, continuity and reliability of
service as may be specified by the Central Government or any authority authorized by it in this
behalf.
e) To call for any such information as may be necessary to determine the tariff for aeronautical
services; and
f) To perform such other functions relating to tariff, as may be entrusted to it by the Central
Government or as may be necessary to carry out the provisions of the Act.
2.1.2 Aeronautical service is defined by AERA Act as under:
a) "aeronautical service" means any service provided—
(i) for navigation, surveillance and supportive communication thereto for air traffic
management;
(ii) for the landing, housing or parking of an aircraft or any other ground facility offered in
connection with aircraft operations at an airport;
(iii) for ground safety services at an airport;
Consultation Paper No. 08/2025-26 Page 28 of 202METHODOLOGY OF TARIFF DETERMINATION OF NAVI MUMBAI INTERNATIONAL AIRPORT
(iv) for ground handling services relating to aircraft, passengers and cargo at an airport;
(v) for the cargo facility at an airport;
(vi) for supplying fuel to the aircraft at an airport; and
(vii) for a stakeholder at an airport, for which the charges, in the opinion of the Central
Government for the reasons to be recorded in writing, may be determined by the Authority;
2.1.3 Airports Authority of India (AAI) being the sole provider of Air Navigation Systems (ANS) services
across the country, shall be responsible for providing ANS at Navi Mumbai International Airport
(NMIA). The tariff for ANS is presently regulated by the Ministry of Civil Aviation (MoCA) at the
national level to ensure uniformity across airports. All assets, expenses, and revenues pertaining to ANS
are accordingly considered separately by the Ministry while determining the tariff for ANS services. In
the present case, as per the arrangement between NMIAL and AAI, NMIAL shall reimburse AAI for
any shortfall between the revenue recovered by AAI at MoCA determined rates and the actual operating
expenditure incurred by AAI, as well as for any capital expenditure undertaken for ANS at NMIA.
Consequently, such reimbursement payable by NMIAL to AAI has been included in the tariff
determination by the Authority as part of the aeronautical cost base of the Airport Operator (refer para
8.2.75 for detailed analysis).
2.1.4 The methodology adopted by the Authority to determine Aggregate Revenue Requirement (ARR) is
based on AERA Act, 2008 read with AERA (Amendment) Act 2019 and 2021, the AERA (terms and
conditions for determination of tariff for Airport Operator) guidelines, 2011 and further guidelines
issued by AERA from time to time.
2.1.5 The Authority has adopted the hybrid-till mechanism for tariff determination for the First Control
Period wherein, 30% of the non-aeronautical revenues are to be used for cross-subsidizing the
aeronautical charges.
2.1.6 The ARR for a given Control Period, under hybrid till, is calculated as:
5
𝐴𝑅𝑅 = ∑𝐴𝑅𝑅
𝑡
𝑡=1
𝐴𝑅𝑅 = (𝐹𝑅𝑜𝑅 𝑥 𝑅𝐴𝐵 )+𝐷 +𝑂 +𝑇 −𝑠 𝑥 𝑁𝐴𝑅
𝑡 𝑡 𝑡 𝑡 𝑡
Where,
t is the tariff year in the Control Period, ranging from 1 to 5
𝐴𝑅𝑅 is the Aggregate Revenue Requirement for tariff year ‘t’
𝑡
FRoR is the Fair Rate of Return for the Control Period
𝑅𝐴𝐵 is the aeronautical Regulatory Asset Base for tariff year ‘t’
𝑡
𝐷 is the depreciation corresponding to the Regulatory Asset Base for tariff year ‘t’
𝑡
𝑂 is the aeronautical Operation and Maintenance expenditure for the tariff year ‘t’
𝑡
𝑇 is the aeronautical taxation expense for the tariff year ‘t’
𝑡
Consultation Paper No. 08/2025-26 Page 29 of 202METHODOLOGY OF TARIFF DETERMINATION OF NAVI MUMBAI INTERNATIONAL AIRPORT
s is the cross-subsidy factor for revenue from services other than aeronautical services under
the hybrid till methodology followed by the Authority, s = 30%.
𝑁𝐴𝑅 is the Non-Aeronautical Revenue in tariff year ‘t’.
𝑡
2.1.7 Based on ARR, Yield per passenger (YPP) is calculated as per the formula given below:
∑5 𝑃𝑉(𝐴𝑅𝑅 )
𝑡=1 𝑡
𝑌𝑖𝑒𝑙𝑑 𝑝𝑒𝑟 𝑝𝑎𝑠𝑠𝑒𝑛𝑔𝑒𝑟 (𝑌𝑃𝑃)=
∑5 𝑉𝐸
𝑡=1 𝑡
Where,
PV (ARR) is the Present Value of ARR. All cash flows are assumed to occur at the end of the
t
year. The Authority has proposed to consider discounting cash flows, one year from the start of
the Control Period.
VE is the passenger traffic in year ‘t’.
t

2.5.3 The Authority has appointed an Independent Consultant, M/s Crisil Limited, to analyse the MYTP
submitted by NMIAL for the First Control Period.
2.5.4 The Authority, through its Independent Consultant has examined the MYTP submitted for the First
Control Period, by verifying the data from various supporting documents submitted by NMIAL such
as audited financials, Fixed Asset Register (FAR), documentary evidence of the process of approval of
capital expenses, operation and maintenance expenses, examining the building blocks in tariff
determination and ensuring that the treatment given is consistent with the Authority's methodology,
approach, etc.
2.5.5 The Independent Consultant requested various clarifications on the information shared by NMIAL to
assess the reasonableness of the proposed CAPEX, operating expenditure, non-aeronautical revenue,
FRoR, etc., for finalizing this Consultation Paper. NMIAL provided additional information based on
clarifications sought and queries raised by the consultants from time to time. The Authority has
proposed to consider the same as part of its examination of the MYTP for the First Control Period of
Navi Mumbai International Airport.
2.5.6 The Authority observed that the assessment of the CAPEX, expansion plans and its phasing is a
technical matter and therefore requires analysis to be undertaken by domain experts. In this backdrop,
the Authority has appointed M/s Engineering Projects (India) Ltd (EPIL) as the CAPEX Consultant for

Consultation Paper No. 08/2025-26 Page 35 of 202PRE-COD LOSSES FOR THE PERIOD FROM FY 2018 TO COD
3. PRE-COD LOSSES FOR THE PERIOD FROM FY 2018 TO COD
3.1 NMIAL’s submissions regarding the period from FY 2018 to COD
3.1.1 NMIAL has, together with the projections for the First Control period, submitted the details of shortfall
for the period from FY 2018 till March 31, 2025, amounting ₹ 79.84 crore.
3.1.2 NMIAL has submitted certain expenses incurred prior to the COD as Pre-COD losses. These Pre-COD
losses are primarily on account of expenses related to the development of airport infrastructure that is
not capitalized. NMIAL has requested the Authority to consider these Pre-COD losses as part of the
tariff computation.
3.2 Authority’s examination regarding the period from FY 2018 to COD
3.2.1 It is noted that Navi Mumbai being a greenfield airport, the airport has been under construction prior to
the COD date of December 25, 2025. The investments and expenditure incurred by NMIAL in the
regulatory building blocks are not available for utilization by users/passengers prior to COD. Therefore,
the users/passengers cannot be asked to pay any aeronautical tariffs before availing of facilities offered
by the airport. In such a scenario, operational losses/gains prior to the airport becoming operational (i.e.
COD) are proposed not to be carried forward to the First Control Period as per the practice being
followed by the Authority.
3.3 Authority’s proposals regarding the period from FY 2018 to COD
Based on the material before it and its analysis, the Authority proposes the following with regards to
the Pre-COD losses for the period from Financial Year 2018 to Airport COD:
3.3.1 Not to consider the pre-COD losses as part of tariff for the period from Company inception to COD for
Navi Mumbai International Airport.
Consultation Paper No. 08/2025-26 Page 36 of 202TRAFFIC FOR THE FIRST CONTROL PERIOD
4. TRAFFIC FOR THE FIRST CONTROL PERIOD
4.1 NMIAL’s submission on traffic for the First Control Period
4.1.1 NMIAL in its MYTP submission has stated that it had appointed M/s ICF Consulting India Pvt. Ltd.
(ICF), an independent agency, to study and project the traffic at Navi Mumbai International Airport.
ICF has undertaken assessment of MMR aviation market, constraints at CSMIA and macro-economic
factors impacting aviation demand for NMIA for the First Control Period.
4.1.2 ICF has forecasted the passenger traffic movement for domestic and international flights at NMIA using
an econometric approach and regression analysis after considering various parameters including but
not limited to:
a) Overall aviation industry in India- trends of traffic growth
b) Overall MMR market - airlines fleet forecast
c) Unserved origin destination routes at MMR
d) GDP growth rates
e) Catchment study based on distance and travel time
4.1.3 Traffic forecast approach considered by ICF is summarized below:
Passenger traffic
M/s ICF has divided the traffic forecast for passengers into three parts (levels), i.e., at MMR, CSMIA
and NMIA with unconstrained and constrained scenarios.
1. MMR unconstrained passenger forecasts
a) Due to the constraints at CSMIA, ICF assessed the actual unconstrained market size of MMR by
considering traffic levels from a year before these constraints began.
b) To estimate the most suitable unconstrained growth rate for CSMIA, during the constrained period,
ICF analyzed passenger growth rates from FY 2016-17 to FY 2023-24 for Delhi and other Tier 1
airports. Basis this comparison, Tier 1 growth rates were found to be the best fit for projecting the
unconstrained MMR size.
c) ICF conducted a short-term bottom-up analysis for FY 2024-25 to FY 2026-27, using actual seat
and passenger data to estimate the growth and adjust the same for demand and supply differences.
If the traffic exceeded pre-COVID levels seen in FY 2018-19 for MMR, forecast followed
unconstrained growth, otherwise, a smooth recovery growth was considered for FY 2025-26 and
FY 2026-27, basis recent traffic growth performance of CSMIA.
d) For econometric forecasts from FY 2026-27 onwards, ICF tested regressions involving multiple
markets and explanatory variables. Based on the best fit in the long term, forecast was driven by
elasticities to GDP (Indian GDP for domestic market; a blend of India and regional GDPs for the
international market). The period selected for the regression analysis was from FY 2013-14 to FY
2018-19.
2. CSMIA unconstrained and constrained passenger forecasts
Consultation Paper No. 08/2025-26 Page 37 of 202TRAFFIC FOR THE FIRST CONTROL PERIOD
a) ICF derived CSMIA's unconstrained traffic from the unconstrained MMR traffic, considering
MMR's growth rates from FY 2023-24 onwards. They forecasted ATMs based on a combination of
seats per ATM, fleet mix, and load factors (LF), using historical and current data for different
regions.
b) The constrained passenger forecast at CSMIA is derived by adjusting the unconstrained ATMs for
capacity constraints, particularly peak-hour limits, leading to split of constrained and spilled ATMS.
c) The final constrained ATMs are then multiplied by the passenger per ATM ratio, to arrive at the
constrained passenger forecasts at CSMIA.
3. NMIA unconstrained and constrained passenger forecasts
a) The unconstrained traffic of NMIA includes the natural catchment area's share from the first year
of operations and the split traffic from CSMIA (difference between unconstrained and constrained
CSMIA) starting FY 2029-30.
b) The natural MMR share of NMIA was estimated by using mobile data mapping to analyse
passenger catchment based on travel time to NMIA and CSMIA. The study mapped 500+ pin codes,
considering both current and planned infrastructure to assess airport preference.
c) The spill from CSMIA to NMIA is estimated on basis of phased traffic absorption of NMIA.
Initially, NMIA assumed to capture its natural catchment, followed by spillover traffic from
constrained CSMIA.
d) Navi Mumbai International Airport’s actual traffic is constrained by passenger handling limits, with
starting at 20 MPPA in FY 2025-26, 50 MPPA in FY 2029-30 and scaling up to 90 MPPA by FY
2034-35. A 15% sweat capacity is also factored into account for peak flexibility.
Air Traffic Movements (ATMs)
a) The number of passenger ATMs was forecasted based on a combination of seats per ATM, fleet
mix and LF
b) Seats per ATMs were calculated based on combination of historical and current seats per ATMs
being operated from CSMIA and other different regions
c) To forecast the seats per ATM, fleet orders for the future were studied to put together a fleet forecast,
to give an expected seats per ATM for each of the regions.
d) Further, based on how the LF at CSMIA and different regions have evolved in the past and based
on the assumption that the airlines will do better in each of the regions with every passing year, the
LFs have been assumed to be rising, increasing the passenger per ATM gradually.
Cargo demand
a) Cargo demand was segmented geographically and by commodity, aligning airport catchments to
relevant cargo types.
b) MMR’s air cargo catchment was analyzed based on road transit time, competition from other hubs
and leakage to alternative hubs.
Consultation Paper No. 08/2025-26 Page 38 of 202TRAFFIC FOR THE FIRST CONTROL PERIOD
c) Due to the strong correlation observed, GDP based forecast (R2 = 0.97) was selected as the baseline
scenario, with optimistic and pessimistic scenarios adjusting projections ± 5%.
d) Over 30 macroeconomic factors including industrial production, exchange rates and private
consumption were used to refine segment wise forecasts for exports, imports and domestic cargo.
e) Bottom-up sectoral analysis of key commodities (e.g. pharmaceuticals, automobiles, electronics,
e-commerce etc.) was performed to understand growth trends and their impact on air cargo demand.
f) MMR’s market share was categorized based on hinterland reach and competing airport dynamics.
g) Capacity distribution between NMIA and CSMIA was assessed, with NMIA expected to become
the primary hub for international cargo.
4.1.4 Traffic forecast for NMIA as submitted by NMIAL for the First Control Period has been presented

4.2 Authority’s examination regarding traffic for the First Control Period
Passenger traffic
4.2.1 The Authority notes that NMIA (greenfield) is the second international airport in the MMR.
Considering the constraints at CSMIA, the two airports are expected to complement each other to meet
the aviation demands of the region.
4.2.2 The Authority reviewed the traffic study conducted by ICF for NMIA and notes that the MMR’s
unconstrained traffic projections indicate that even with the combined traffic handled by both airports
in the MMR, a significant demand will remain unserved until FY 2029-30.

NMIAL traffic projection MIAL traffic projection Unserved traffic at MMR level
Note: Tariff order for 4th Control Period of MIAL provides traffic projection till FY 2028-29. For FY 2029-30, traffic equal to
CSMIA capacity of 55 MPPA has been considered.
4.2.3 The Authority observes that during the period from FY 2013-14 to FY 2018-19, traffic growth at
CSMIA was approximately 0.65 times that observed at Indira Gandhi International Airport (IGIA),
New Delhi, as shown in Table 10 below. This divergence is primarily due to capacity constraints at
CSMIA. While CSMIA and IGIA exhibited comparable traffic levels until 2012, IGIA subsequently
experienced higher growth due to absence of such constraint. Accordingly, the unconstrained growth
projections for the MMR appear reasonable when assessed in the context of historical trends at other
metro airports without capacity constraints.
Table 10: Comparison of traffic growth trend at CSMIA & IGIA
Particular (in Mn) FY 2013-14 FY 2018-19 CAGR Ratio(A/B)
CSMIA Domestic 21.88 34.39 9.47%

IGIA International 12.68 18.70 8.09%
IGIA Total - B 36.87 69.23 13.43%
4.2.4 The Authority further notes that the passenger traffic forecast of 11.98 million for FY 2025-26, as
submitted by NMIAL is premised on the assumption that domestic operations would commence by
May 31, 2025, and international operations by July 31, 2025. However, in view of the delay and
subsequent revisions in planned COD (domestic operations commenced on December 25, 2025, and
international operations scheduled to commence from April 1, 2026), the traffic projection for FY 2025-
26, being the initial year of the First Control Period requires suitable adjustments to reflect the reduced
period of operations during the year.
4.2.5 The Authority notes that between FY 2025-26 to FY 2029-30, notwithstanding the operationalization
of NMIA, traffic at CSMIA is expected to remain constrained due to capacity limitations. Consequently,
there exists a significant quantum of latent and unserved passenger demand at the MMR level, estimated
at approximately 18 to 22 MPPA (as per Figure 2). Such demand is expected to be progressively
absorbed by NMIA over the First Control Period.
Consultation Paper No. 08/2025-26 Page 40 of 202TRAFFIC FOR THE FIRST CONTROL PERIOD
4.2.6 In view of the revised Commercial Operations Date (COD) of December 25, 2025, passenger traffic
projections have been realigned to reflect change of COD against May 31, 2025. Accordingly, domestic
traffic for FY 2025-26 have been moderated and assumed for a truncated operational period of three
months, instead of ten months considered earlier in NMIAL’s submission. Further, international
operations are now assumed to commence from April 01, 2026.
4.2.7 The Authority observes that NMIAL has indicated a traffic trigger for initiation of Phase III
development during FY 2026-27. Accordingly, in its Multi-Year Tariff Proposal (MYTP), NMIAL has
proposed commencement of Phase III development in FY 2026-27 with envisaged operationalization
in FY 2029-30.
4.2.8 However, in view of the delay in commencement of commercial operations at NMIA, the Authority is
of the considered view that the traffic trigger for Phase III is likely to materialize towards the later part
of FY 2026-27. Consequently, the Authority has assumed that construction activities for Phase III would
commence in FY 2027-28. Further, considering the scale and complexity of the proposed expansion
works under Phase III, the Authority has assumed a minimum construction period of approximately
three (3) years and has hence estimated its likely completion in FY 2030-31.
4.2.9 In view of the above, passenger traffic projections attributable to Phase III capacity augmentation, as
considered by NMIAL in its submission, have not been factored into the Authority’s traffic assessment
for the First Control Period. During the intervening construction phase, NMIAL is expected to
undertake optimal asset utilization measures to sweat existing terminal (T1) capacity to accommodate
the traffic growth. Based on these revised assumptions, the Authority therefore proposes the passenger
projections for the First Control Period as below:
Table 11: Passenger traffic proposed by Authority for the First Control Period

2029-30 18.66 7.34 26
Total 73.19 26.93 100.12
Air Traffic Movement (ATM)
4.2.10 Authority has reviewed the assumptions considered by NMIAL as per ICF study for projecting the
ATMs for the First Control Period. These assumptions include forecast based on seats per ATM, fleet
orders for the future put together a fleet forecast, to give an expected seats per ATM for each of the
regions. Then, Current Load Factors (LFs) were mapped, based on passenger data from Adani managed
airports and seat data from OAG. Based on historical evolution of the LFs at CSMIA for the regions
and the assumption that the airlines will do better in each of the regions with every passing year, the
LFs have been assumed to be rising, increasing the passenger per ATM gradually.
4.2.11 Further, the Authority notes that, in view of the revised COD of December 25, 2025, ATM projections
need to be realigned to reflect change of COD against May 31, 2025, considered earlier in NMIAL’s
submission.
Consultation Paper No. 08/2025-26 Page 41 of 202TRAFFIC FOR THE FIRST CONTROL PERIOD
4.2.12 Accordingly, domestic ATMs for FY 2025-26 have been moderated and assumed for a truncated
operational period of three months, instead of ten months considered earlier in NMIAL’s submission.
Further, international operations are now assumed to commence from April 01, 2026.
4.2.13 Further, phase III construction is likely to be completed by FY 2030-31 as explained in para 4.2.8,
therefore ATM projections attributable to Phase III capacity augmentation, as considered by NMIAL in
its submission, have not been factored into the Authority’s assessment of ATM for the First Control
Period. During the intervening construction phase, NMIAL is expected to undertake optimal asset
utilization measures to sweat existing terminal (T1) capacity to accommodate the traffic growth. Based
on these revised assumptions, the Authority therefore proposes the ATM projections for the First
Control Period as below:

Cargo demand
4.2.14 The Authority has reviewed the assumptions considered by NMIAL in projecting the cargo volume for
the First Control Period. These assumptions include projections derived from the GDP-based model,
combined with the multivariate analysis (includes analysis via 30 macroeconomic factors, which are
key drivers for air cargo growth) which provides a fair representation of the market's likely trajectory
in the coming years and the same was further validated via bottom-up analysis.
4.2.15 As per the ICF study, NMIA is expected to become the primary international airport for MMR. On this
account, high-yield international belly capacity is expected to get concentrated in NMIA, given higher
proportion of international pax connections. In addition, domestic belly capacity is also likely to be
split between CSMIA and NMIA. In view of the revised COD of December 25, 2025, cargo volume
projections have been realigned to reflect change of COD against May 31, 2025, considered earlier in
NMIAL’s submission.
4.2.16 Accordingly, domestic cargo volume for FY 2025-26, have also been moderated and assumed for a
truncated operational period of three months, instead of ten months considered earlier in NMIAL’s
submission. Further, international operations are now assumed to commence from April 01, 2026.
4.2.17 Further, phase III construction is likely to be completed by FY 2030-31 as explained in para 4.2.8,
therefore cargo projections attributable to Phase III capacity augmentation, as considered by NMIAL
in its submission, have not been factored into the Authority’s cargo assessment for the First Control
Period. During the intervening construction phase, NMIAL is expected to undertake optimal asset
utilization measures to sweat existing cargo terminal capacity to accommodate the cargo growth. Based
Consultation Paper No. 08/2025-26 Page 42 of 202TRAFFIC FOR THE FIRST CONTROL PERIOD
on these revised assumptions, the Authority therefore proposes the cargo projections for the First
Control Period as below:

4.3 Authority’s proposals regarding traffic for the First Control Period
Based on the available facts and analysis thereupon, the Authority proposes the following with regard
to traffic forecast for the First Control Period.
4.3.1 To consider the passenger, ATM and cargo traffic for the First Control Period for NMIA as per Table
14.
4.3.2 To true up the traffic volume (passenger, ATM and cargo) on the basis of actual traffic in the First
Control Period while determining tariff for the Second Control Period.

5. CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET
BASE (RAB) FOR THE FIRST CONTROL PERIOD
5.1 Background
5.1.1 RAB is an essential element in the process of aeronautical tariff determination. The return to be
provided on RAB constitutes a considerable portion of the ARR. To encourage the participation of the
private sector in airport development and operations, investors must be fairly compensated for the
capital outlays involved. At the same time, to safeguard the interests of the airport users, it must be

5.3.8 The Authority notes that NMIAL for the First Control Period, had proposed total CAPEX of ₹ 57,332
crore, out of which ₹ 22,531 crore pertains to phases I and II and ₹ 34,337 crore pertains to phase III and
balance pertains to minor/sustainable CAPEX of ₹ 464 crore.
5.3.9 The Authority notes that as per the submission by NMIAL, the capitalization of the phase III project is
assumed to be in FY 2029-30. However, it is likely that due to the delay in operationalization of phases
I and II, the development of phase III will also be delayed. Therefore, the Authority proposes to consider
the CAPEX for phase III on incurrence basis subject to its reasonableness and prudence check during
the true up exercise in Second Control Period.
5.3.10 During the site visit by the CAPEX consultant, tariff consultant along with AERA official from July 3
to July 5, 2025, and later NMIAL submitted a revised CAPEX proposal for the First Control Period. A
comparative between the original MYTP figures and the revised proposal is shown below:

Land Development Works and its related costs
Background
5.3.11 The land development costs as per the MYTP for the Navi Mumbai International Airport (NMIA) project
comprises the pre-development works undertaken by CIDCO amounting to approximately ₹3,800 crore
and the subsequent site preparation and earthworks undertaken by NMIAL amounting to approximately
₹1,900 crore. These works were carried out across the entire land parcel of approximately 1,160 hectares
(2,866 acres), which forms the development footprint for Phase I and Phase II of the airport.
During the site visits conducted by the Tariff Consultant and CAPEX Consultant on April 28, 2025 to
April 30, 2025, AERA Tariff division officials along with Tariff and CAPEX consultants on July 3, 2025
to July 5, 2025 and the Authority along with Tariff Consultant, CAPEX consultant and AERA officials
on December 23, 2025, number of discussions were held with representatives of NMIAL and CIDCO
regarding the land development works undertaken at site, based on which the key aspects of site
development as brought out by NMIAL and CIDCO are elaborated below.
Natural Topography and Site Conditions Prior to Development
5.3.12 The NMIA project site is located south of Panvel Creek, with Thane Creek to the west and the Gadhi
River to the east. Prior to the commencement of pre-development works in 2017, the site exhibited
highly varied natural topography and complex geotechnical characteristics. The terrain generally sloped
from the south and west towards the north and east, and included several natural features such as
extensive low-lying areas in the northern, central and eastern portions, Ulwe Hill with an elevation of
approximately 104 metres, and Ganeshpuri Hill located in the northern portion of the site. The Ulwe
River flowed through the central portion of the site from south to north. In addition, two Extra High
Voltage Transmission (EHVT) lines traversed the eastern and western parts of the site, and nine village
gaothans existed across the western, northern and southern portions of the airport site.

FIRST CONTROL PERIOD
Figure 5: NMIA Site Sub-Soil Conditions (2017)
5.3.13 The natural drainage pattern of the area/site directs water flow towards Panvel Creek in the north and
the Ulwe River in the east. Large portions of the northern, central and eastern areas are low-lying and
prone to flooding during the monsoon season and high tide conditions. Sub-soil conditions across the
site vary significantly, with soft marine clay deposits observed in the northern and eastern portions of
the site. These natural topographical and geotechnical conditions posed significant challenges and
required comprehensive land development works across the entire NMIA site.
Pre-Development Works Undertaken by CIDCO
5.3.14 The most prominent feature of the site was Ulwe Hill with a height of approximately 104 metres,
followed by Ganeshpuri Hill, together covering a footprint of more than 250 hectares. Apart from being
a major obstacle within the Obstacle Limitation Surface (OLS) of the proposed airport, Ulwe Hill also
fell directly within the alignment of both the southern and northern runways of the greenfield airport.

FIRST CONTROL PERIOD
5.3.15 In view of the diverse natural topographic and geo-technical conditions and complex site characteristics,
extensive pre-development works were undertaken by CIDCO to render the land suitable for airport
construction and enable commencement of construction of Airport infrastructure by NMIAL. These
works are defined as Pre-Development Works under the Concession Agreement for the NMIA project
and were subsequently novated to NMIAL. As per clause 12.9.1 of the Concession Agreement, the Pre-
Development Works as specified in Annexure of Schedule B of the Concession Agreement include:
(i) cutting of hills (including Ulwe Hill) up to approximately 8 metres above mean sea level
(AMSL) and filling of low-lying areas up to approximately 5.5 metres AMSL;
(ii) ground improvement works;
(iii) construction of sea wall or retaining wall and road along the boundary of the site,
(iv) shifting and relocation of existing utilities;
(v) construction of the Ulwe River diversion channel (Ulwe Recourse Channel – URC); and
(vi) re-routing of Extra High Voltage Transmission Lines passing through the project site.
5.3.16 Consequently, cutting of Ulwe Hill constituted a critical prerequisite for commencement of airport
construction works. The basalt rock obtained from the hill cutting operations served as an essential
resource for filling the extensive low-lying areas in the northern half of the airport site. These works
enabled the development of a platform at 5.5 metres AMSL, which formed the base for further site
development activities. CIDCO had awarded the land development works in multiple packages
(Packages 1 & 2, and Packages 3 & 4) during 2016, and the works commenced in April 2017. Under
these contracts, hill cutting operations were undertaken to reduce elevations to approximately 8.0 metres
AMSL, while fill areas were developed to achieve a platform level of approximately 5.5 metres AMSL.
The land development works executed by contractors appointed by CIDCO were completed in June
2022.
Development Works Undertaken by NMIAL
5.3.17 Following completion of the above works by CIDCO, NMIAL was required to raise the site level further
from approximately 5.5 metres AMSL to about 8.5 metres AMSL in order to create a stable development
platform suitable for airport infrastructure. This activity required large quantities of rock fill, which were
primarily obtained from cutting Ulwe Hill, Ganeshpuri Hill and other hillocks located within the site.
5.3.18 Overall, approximately 60 million cubic metres of rock and earth material excavated from Ulwe Hill
and other hillocks within the site were utilized to fill the low-lying areas located in the northern, central
and eastern portions of the NMIA site.
5.3.19 Subsequently, after the filling of the site up to 5.5 metres AMSL, it was observed that Ulwe Hill retained
additional rock material which required cutting and disposal to achieve the final required levels.
Accordingly, NMIAL appointed Larsen & Toubro (L&T) to undertake additional hill cutting and filling
works from 5.5 metres AMSL to approximately 8.0 metres AMSL, and the excess hill cutting and off-
site disposal works were completed in 2024.

FIRST CONTROL PERIOD
Figure 7: Aerial view of NMIA site depicting site level/contours
Technical Necessity for Land Development of Entire 1,160 hectares
5.3.20 From a technical perspective, it is evident that a significant portion of Ulwe Hill lies within the footprint
of Phase I and Phase II development and also obstructs the Obstacle Limitation Surface of the southern
runway. Therefore, the hill had to be cut during Phase I and Phase II itself in order to create the required
level platform for airport development. Further, a substantial quantity of the excavated rock from Ulwe
Hill was required to fill the extensive low-lying areas across the NMIA site, particularly in the northern,
central and eastern parts.
5.3.21 No development and initiation of construction of any element of Airport infrastructure including Phase
I and Phase II of NMIAL would have been possible unless the entire Ulwe Hill and other hillocks were
cut and the excavated material was utilized for filling within the airport site. The terrain conditions in
the northern portion of the site required land filling to be carried out approximately 5–6 years in advance
to allow sufficient time for soil consolidation and stabilization. These technical considerations
necessitated that land development works need to be undertaken across the entire site area of 1,160
hectares, through cutting operations in the western and southwestern portions and filling operations in
the northern, central and eastern portions.
Efficient Utilisation of Excavation Rock Material
5.3.22 The excess rock generated because of hill cutting operations could not have been commercially disposed
of outside the airport site only to be procured again at a later stage for development of subsequent phases.
Utilization of the excavated rock within the airport site avoided unnecessary transportation and disposal
costs and eliminated the need to procure similar material at higher market rates for future phases. This
approach therefore represents efficient resource utilization and prudent cost optimization in support of
the overall aeronautical development plan.
Consultation Paper No. 08/2025-26 Page 61 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE
FIRST CONTROL PERIOD
Authority’s assessment and views
5.3.23 Based on the site visits, site inspection and review of the CIDCO/NMIAL technical studies through the
independent Tariff and Capex consultants engaged by AERA, AERA tariff division officials and based
on the site visit of the Authority along with Tariff Consultant, CAPEX Consultant and AERA Tariff
Division officials on December 23, 2025, the Authority has assessed that the land development activities
at the NMIA site are highly interdependent in nature in view of the inherent complexities of terrain,
hydrology and surrounding infrastructure necessitating multiple development components to be
executed in an integrated and simultaneous manner.
5.3.24 Any attempt to carry out these works in isolation or on a piecemeal basis would create significant
engineering, safety and operational challenges, and could render the site unsuitable for airport operations
and future development and expansion. Furthermore, the scale, magnitude and technical complexity
associated with the development of the NMIAL site are unprecedented in the Indian airport sector. In a
comparable instance, the full land development cost was allowed in the case of Manohar International
Airport, Goa, during tariff determination for its First Control Period. In view of the above, the Authority
is of the view that the components of Pre-Development Works listed in the Concession Agreement under
the Annex to Schedule B could not have been undertaken on a piecemeal basis. For example, hill cutting
cannot be done partially or else would be an obstacle in the airport operations path, river running across
the site cannot be diverted partially, etc. Therefore, activities such as hill cutting, river diversion and
relocation of utilities inherently require simultaneous execution on entirely basis across the entire site in
order to enable development and construction of the airport infrastructure (Terminal Building, Runways,
Apron, Taxiways, ATC Tower etc.) to begin for the airport operations to commence. The entire Pre-
Development Works therefore act as enabling activities for the commencement of aeronautical
operations and are intrinsically linked with the development of different phases of airport starting with
phase I and II.
5.3.25 In view of the above analysis, the Authority is of the view that the components of Pre-Development
Works listed in the Concession Agreement under the Annex to Schedule B could not have been
undertaken on a piecemeal basis due to diverse natural topographic and geo-technical conditions of the
site alongwith its complex characteristics as brought out in the preceding paras. Activities such as hill
cutting, river diversion and relocation of utilities inherently require simultaneous execution on entirety
basis across the entire site in order to enable the commencement of airport operations. The entire Pre-
Development Works therefore act as an enabling activity for the commencement of aeronautical
operations starting with Phase I and Phase II development.
5.3.26 Also, the aeronautical portion of Phase I and Phase II lies within the footprint of hill-cut areas and
previously flood-prone zones, making full-site leveling a prerequisite for the construction of airside
infrastructure. Further, the excess hill cut material could not have been economically moved outside the
airport site only to be re-procured later for future development phases at higher market rates. Utilization
of the excavated material within the site therefore represents optimal resource utilization. The
requirement for advance land filling in the northern portion of the site to allow adequate soil stabilization
also demonstrates that the works were undertaken in accordance with the specific geotechnical
requirements of the site. Moreover, the Concession Agreement does not envisage phasing of the Pre-
Consultation Paper No. 08/2025-26 Page 62 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE
FIRST CONTROL PERIOD
Development Works, and as per Clause 12.9.1 of the Concession Agreement, the Concessionaire was
required to complete the Pre-Development Works already initiated by CIDCO.
5.3.27 In view of the technical, operational, contractual and peculiar geographical conditions as highlighted
and deliberated above, the Authority in the light of the relevant provisions in the Concession Agreement,
MOU between GoI and NMIAL, AERA Act 2008 & AERA orders proposes to consider the land
development cost for the entire site of area 1,160 hectare and its further comprehensive analysis is as
detailed below:
A - Site preparation & earthworks along with pre-development works done by CIDCO
NMIAL has submitted the cost of ₹ 5,664 crore towards site preparation and earthworks done by
NMIAL and pre-development works carried out by CIDCO. The details are as follows:

In view of the existing diverse natural topographic & geotechnical conditions, several site
development works had to be initiated by CIDCO to enable subsequent construction of airport
infrastructure by NMIAL. The CAPEX for pre-development works claimed in the MYTP submitted
by NMIAL was ₹ 3,665 crore. Subsequently, the amount was revised to ₹ 3,747 crore based on
reconciliation till October 2025 by CIDCO and later informed by NMIAL vide email dated
November 11, 2025. Breakup for pre-development works done by CIDCO has been provided in the

These site development works undertaken by CIDCO summarized in the above table are termed as pre-
development works and are stipulated in the Annex (Schedule – B) of the CA. These works are
elaborated below:
1. Land development works
The work includes land development at the site having 1,160 Ha area, which was comprising of
undulations and Ulwe hill range passing across having altitude of 104 m AMSL along with deep
marshy land. The pre-development works on the entire site was essential to not only level the site at
5.5 ASML but also to enable the laying of utility networks for proper functioning of aeronautical
infrastructure and associated works required to be developed in subsequent phases. Also, the levelled
and graded site and surroundings are required for uninterrupted aeronautical operations and for
ensuring effective drainage of the entire site.
Further, the existing hill on the site was required to be levelled upfront for ensuring uninterrupted
Airport operations in future because the cutting and levelling work requires controlled blasting,
which would lead to interruptions of operations. The details of works undertaken are as below:
a. Cutting of hills
The works include cutting of the hills to make the site level at 5.5m AMSL over which the
development of various aeronautical infrastructure and facilities were planned for NMIA.
CIDCO had divided the entire site into four parts (Package I, II, III & IV), to undertake the
development works simultaneously for expeditious completion.
b. Other Miscellaneous works
The work comprises of ground improvement works which include disposal & spreading of
soil/slush material, soil stabilization, site levelling & compaction as ground improvement
measures and construction of sea wall / retaining wall and northern boundary road which
includes site protection works along with northern boundary by constructing retaining walls to
prevent back water & erosion.
2. Diversion of the Ulwe river channel (Ulwe Recourse Channel / URC)
This work includes diverting the Ulwe river away from the proposed site.
a. Cutting of 120 m/ 200 m wide channel along the southern boundary of the Airport for diversion
of the Ulwe river of 3.5 km length near the bridge on SH-54 to Moha creek. This also includes
construction of 10 m bund on either side of channel and the lining of channel.
b. Crossing on the Aamra Marg by culvert/bridge
3. Re-routing of extra High Voltage Transmission lines passing through the site
Consultation Paper No. 08/2025-26 Page 65 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE
FIRST CONTROL PERIOD
The work includes the diversion of Electric High Voltage Transmission line (EHVT) which was
imperative to facilitate the availability of clear site on which aeronautical infrastructure was required
to be taken up.
The diversion of EHVT were assigned to M/s Tata Power and M/s MSETCL on deposit work basis.
The other associated works such as service road for rerouting EHVT Line, construction of 260 m
long bridge near Vahal over Ulwe river, construction of approach road for sub-station Belapur etc.
The works were undertaken by M/s Tata Power & M/s MSETCL on deposit work basis.
4. Excess hill cutting & its disposal outside NMIA Site
After the completion of entire pre-development work on the entire site, there was still a part of hill
left, which was required to be disposed of.
The Independent Consultants have examined all the tender documents / agreements of the work packages
for the above pre-development works and found that the works were awarded based on the competitive
bidding as per CIDCO procurement policy and followed codal procedures. For the hill cutting works,
the quantity was also assessed based on available records and quantity claimed towards cutting was
found to be reasonable. The rates quoted by the bidders were also scrutinized by comparing them with
market rates, duly analysed based on MORTH/ PWD rate, which was also found to be reasonable.
In addition to the above, completion of Rehabilitation & Re-Settlement (R&R) of nine village gaothans
located on NMIA site by CIDCO was primary pre-requisite for both pre-development works by CIDCO,
and subsequent airport development works by NMIAL. R&R and all pre-development work have been
completed by CIDCO. The expenditure incurred by CIDCO for R&R is not part of NMIA project cost.
Further, the Authority has examined the key provisions of the Concession Agreement signed between
NMIAL and CIDCO, the Memorandum of Understanding (MoU) executed between Ministry of Civil
Aviation, Government of India and NMIAL and the provisions of AERA Act and AERA order related to
treatment and analysis of the pre-development expenses which are elaborated below.
5. Provisions for consideration of Pre-Development work as part of Capital Expenditure:
(i) Concession Agreement executed between NMIAL and CIDCO (Concessioning Authority)
The key provisions of the CA in relation to the soft loan forming the part of the CAPEX are as below:
• Clause 12.9.1: “The concessionaire acknowledges the authority has undertaken certain pre-
development works at the site as specified in annex of Schedule B (“Pre-development Works”), and
the concessionaire hereby accepts the receipt of the site under clause 10.2 subject to the continuation
of such Pre-development works. Subject to the provision of clause 12.9.2, the amount paid/payable
by the authority for the implementation of the Pre-development works up to an amount of ₹ 3420
crore shall be deemed as soft loan (“Soft Loan”) for the purpose of this agreement. The Authority
acknowledges, agrees and undertakes that it shall provide the Soft loan in accordance with the
provisions of this clause 12.9.”
• Clause 12.9.2: “An amount of ₹ 430 crore out of the Soft loan shall be considered as Authority’s
equity capital infusion in the Concessionaire in consideration for the subscription of Authority’s
share, and the Soft loan shall be subject to reduction of such amount from repayment accordingly”.
Consultation Paper No. 08/2025-26 Page 66 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE
FIRST CONTROL PERIOD
• Clause 12.9.3: “The concession agrees and undertakes that any amount or expenditure in excess
thereof in respect of the land development works forming part of the pre-development works, which
are assigned or novated to it in accordance with the terms here of and have resulted due to change
in scope attributable to the concessionaire, shall be born directly, entirely and solely by the
concessionaire and the authority shall not provide any compensation, cost, amount in form of
additional soft loan or otherwise for any such excess. Any additional cost incurred on the
implementation of the land development works otherwise, shall be paid by authority in the form and
manner provided in the LDS agreement. Any such additional amount that may be paid by the
authority shall not be considered as part of the soft loan”.
• Clause 12.9.7: “Assets forming part of the pre-development works and financed by the soft loan
shall be considered as a part of capital expenditure for the purposes of the determination of
aeronautical charges by AERA”.
(ii) Memorandum of Understanding (MoU executed between Ministry of Civil Aviation,
Government of India and NMIAL
The key provisions of the MoU dated April 11, 2018, between MoCA, GoI and NMIAL forming part of
CA, stipulate incremental capital and inclusion in RAB as below:
• Clause 2.2.9 “Asset forming part of the pre-development works and financed by soft loan shall be
considered as part of capital expenditure for the purposes of the determination of aeronautical
charges. The interest on solo, pertaining to pre-development works inside and outside the side to
the extent it is part of mandate cost under the concession agreement, will be taken into calculation
of FROR at:
a) 0% cost of capital, if no interest is payable/ paid by the concessionaire to the Authority on the
soft loan and
b) The applicable rate of interest as maybe payable/paid by the concessionaire to the authority on
exercise of optional deferment of the linkage date for the repayment of the soft loan as per
proviso (ii) to clause 12.9.6 of the concession agreement to keep the net present value of the soft
loan as on the appointed date for determination of aeronautical charges”.
• Clause 2.2.10: “Incremental capital cost, if any, born by the concessionaire for land development
works for airport activities over and above the soft loan, to the extent required for the project work.
As per the terms of the concession agreement, would be considered for the inclusion in the regulated
asset base with appropriate depreciation rate, by AERA for determination of aeronautical charges”.
(iii) Provision of AERA, Act, 2008
• Section 13(1)(vi) of the AERA Act, 2008 states that the Authority shall consider any concession
offered by the Central Government through an agreement, memorandum of understanding, or any
other similar arrangement while performing its regulatory functions.
• In this context, Clauses 2.2.9 and 2.2.10 of the Memorandum of Understanding signed on April 11,
2018 between Navi Mumbai International Airport Limited (NMIAL) and the Government of India
provide certain concessions related to the development of the Navi Mumbai International Airport
Consultation Paper No. 08/2025-26 Page 67 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE
FIRST CONTROL PERIOD
project. Therefore, under the above provision of the AERA Act, the AERA is required to take these
concessions into account. This means that the pre-development costs incurred for the airport project,
as provided under Clauses 2.2.9 and 2.2.10 of the MoU stipulated as part of Concession Agreement
executed between NMIAL and CIDCO need to be considered as part of the capital expenditure for
the airport and included in the Regulatory Asset Base. Accordingly, the Authority has proposed to
consider the pre-development cost as part of RAB for the computation of tariff for NMAIL.
(iv) AERA Order 35/2017-18 in the matter of determination of Useful Life of Airport Asset
• The Authority, after taking into account the above considerations, has capitalized the pre-
development expenditure as part of the Regulatory Asset Base (RAB). This capitalized amount has
been amortized over a period of 40 years, which corresponds to the duration of the Concession
Period. The amortization has been carried out for the purpose of calculating depreciation in
accordance with AERA Order No. 35/2017-18, which prescribes the useful life of capital assets
under the relevant provisions of the order.
• Specifically, the said order provides that Land Development Cost relating to leased land should be
amortized over the lease period. In line with this regulatory provision, the authority has treated the
pre-development costs associated with land as a capitalized asset and spread the cost over the
remaining concession/lease period of 40 years. Accordingly, based on the above regulatory
framework and treatment, the authority has also considered the land development cost as part of the
RAB. Consequently, this cost has been made eligible for the calculation of Return on Assets, in the
same manner as other capital assets that form part of the RAB. This approach ensures consistency
with the regulatory guidelines and provides parity in the treatment of land-related development costs
with other capitalized infrastructure assets included in the RAB.
6. Reconciliation of Pre Development Cost
Based on the examination of provisions of the Concession Agreement and MoU above, the Authority
notes that the expenditure of ₹3,420 crore incurred by CIDCO has been stipulated towards pre-
development works and that it forms part of the overall project cost of the NMIA project.
However, in the MYTP submitted by NMIAL, the Airport Operator initially claimed a pre-development
cost of ₹3,665 crore. Subsequently, this amount was revised to ₹3,747 crore based on the reconciliation
of costs carried out by CIDCO up to October 2025 which was later communicated by NMIAL through
an email dated November 11, 2025. The details of this revised cost are summarized in Table 22 above.
Now, the CAPEX Consultant (M/s EPIL), considering the facts available and examination of supporting
information submitted by NMIAL, in its assessment has recommended limiting the pre-development
cost to ₹3,420 crore for the First Control Period. This amount of ₹3,420 crore is already stipulated in the
Concession Agreement and represents verified expenditure incurred by CIDCO. The Authority also
notes that this recommendation of Capex Consultant is subject to submission of final reconciled and
formally approved cost figures by CIDCO and NMIAL.
Accordingly, the Authority proposes to consider the recommendation of the Independent Consultants for
the pre-development cost to ₹3,420 crore for the First Control Period and is also of the recommended
view that any difference or revised amount, if confirmed later by CIDCO and NMIAL, may be

considered post-analysis of reasonability and necessity at the stage of stakeholder consultation, prior to
the issuance of the Tariff Order.
I. Site preparation & earthworks by NMIAL
NMIAL was required to undertake development works over the site prepared by CIDCO at an
elevation of 5.5M AMSL, to achieve the final finished level of 8M AMSL. NMIAL has submitted
that an amount of ₹ 1,917 crore has been incurred towards site preparation & earthwork activities.
The submitted cost also includes ₹ 105 crore towards price adjustment and ₹ 73 crore towards
various change orders associated with the said works.

NMIAL has awarded the EPC contract (EPC-1) for the site preparation and earthworks on August 31,
2019, with the condition that a Notice to Proceed (NTP) will be issued before commencement of work.
However, the NTP was issued in May 2022 due to COVID-19 disruptions and associated delays,
resulting in a 32-month gap between contract award and actual commencement. Accordingly, a price
adjustment of ₹105 crore was made to EPC-1 contract.
It is observed that the delay in handover of the site was not attributable to the contractor. Further, the
CAPEX consultant has found price adjustment reasonable due to the outbreak of global COVID-19
pandemic and increase in cost of basic input materials due to delay period of two & half years (32
months). The cost of the work pertaining to site preparation & earth work amounting to ₹ 1,917 crore
Consultation Paper No. 08/2025-26 Page 69 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE

was analyzed & examined based on MORTH/CPWD DSR rate analysis and market rates and found to
be reasonable, necessary and thus proposed.
Based on the analysis as brought out above from para 5.3.11 onwards, the cost considered by Authority
towards pre-development works done by CIDCO and the site preparation & earthworks done by NMIAL
are summarized in table below:

Consultation Paper No. 08/2025-26 Page 70 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE
FIRST CONTROL PERIOD
The Authority through its Independent Consultants notes that NMIAL has awarded the EPC-2 contract
for the airside development works on August 31, 2019, with the condition that a Notice to Proceed (NTP)
to be issued before commencement of works. However, the NTP was issued in May 2022 due to COVID-
19 disruptions and associated delays, resulting in a 32-month gap between contract award and actual
commencement. Accordingly, a price adjustment of amount is ₹ 211 crore was made to EPC-2 contract.
It is observed that the delay in handing over of the site was not attributable to the contractor and the
same was due to the outbreak of global COVID-19 pandemic which was beyond control. Therefore,
price adjustment claimed due to increase in cost of basic input materials due to delay period (32 months)
is found reasonable.
The Authority further notes that the total amount of ₹ 2,041 crore claimed against Airside Development
works also includes an amount of ₹ 319 crore against unawarded cost. Out of this unawarded cost of ₹
319 crore, NMIAL has recently awarded General Aviation (GA) apron work for an amount of ₹ 278
crore vide a change order dated July 25, 2025 in EPC-2 contract. The components of this change order
include pavement, drains, OWS, Jet Blast Deflector, AGL, utilities work & provisional sum works
towards utilities works, removal of silt pond & enabling works. Therefore, the difference of ₹ 41 crore
which is still unawarded has not been considered.
Analysis of reasonability of cost of airside pavement (runway, taxiway, apron)
The Authority through its Independent Consultants has examined the CAPEX in accordance to AERA
order No. 07/2016-17 on June 13, 2016, which provided the normative cost for the construction of
pavement (Apron, Taxiway and Runway). The Authority compared the cost awarded relating to Runway,
Apron and Taxiway works with inflation-adjusted normative rate.
The normative cost of Airside pavement is slightly higher than against the cost per sqm. submitted by
NMIAL which is ₹ 4,987 per sqm. Further, the rate was also analysed based on MoRTH/ CPWD rate
analysis and the same was found to be reasonable.
The comparative of airside works as submitted by NMIAL and as observed by the Authority through its
Independent Consultants is set out in table below:
Based on the above analysis, the cost considered by Authority is given in table below:

Assessment of terminal building area per Peak Hour Passenger ( PHP)
The PTB area proposed was examined in accordance to IATA norms. As per IATA norms the area in
sqm/PHP is stipulated as 30 sqm. The built-up area of PTB is 2,31,354 sqm for 6,745 PHP is slightly
higher than the requirement of IATA norms but found to be in compliance with concession agreement
which stipulates for a min. area of 30 sqm. per PHP.
The floor wise area break-up for the terminal building is given below:

The unit area of the building is 34.30 sqm which is in line with Concession Agreement i.e. “the unit are
of terminal building shall be of minimum 30 sqm.”
Assessment of cost of passenger terminal building
The Authority notes that the CAPEX towards Passenger Terminal Building as submitted by Airport
operator is ₹ 3,584 crore which is also inclusive of unawarded works amounting to ₹ 167 crore as below:
a. Digital & physical artwork
NMIAL has submitted ₹ 71 crore for digital & physical art program including construction works.
It is noted that two contracts on digital art had already been awarded by NMIAL. Since, it’s an
additional requirement raised by NMIAL which is yet to be awarded, therefore, the proposed amount
of ₹ 71 crore under non-EPC work has not been considered and same would be considered at the
time of issuance of final Tariff Order based on actual incurrence.
b. Security equipment’s (Body scanners/CTX/ATRS)
NMIAL has submitted ₹ 26 crore towards security equipment’s (Body scanners/CTX/ATRS) under
non-EPC works but later on the same was removed in the revised CAPEX submitted by NMIAL
under unawarded work dated September 09, 2025.
Therefore, ₹ 26 crore has not been considered by the Authority.
c. Other misc. works (Scope gap/Additional changes)
NMIAL has submitted ₹ 68 crore in revised list of unawarded work as miscellaneous works towards
Scope gap/Additional changes and the same has not been considered based on the reasons below:
a. No details/break-up submitted for review & acceptance
b. This expenditure is yet to be incurred
Therefore, ₹ 68 crore has been disallowed & may be considered at the time of issuance of final tariff
order based on actual incurrence.
Hence a total amount of ₹ 167 crore (₹ 71 crore + ₹ 26 crore + ₹ 70 crore) would be considered at
the time of issuance of final tariff order based on actual incurrence basis.
Hence, proposed cost for the PTB has been restricted to ₹ 3,417 crore (₹ 3,584 crore- ₹ 167 crore).
The Authority through its Independent Consultant has assessed the cost of the Passenger Terminal
Building (PTB) based on CPWD Plinth Area Rates (PAR), DSR, and prevailing market rates, and has
also benchmarked the estimates with comparable airport projects. Accordingly, the total estimated cost
of the PTB works out to ₹ 3,417 crore, corresponding to a per sqm. cost of ₹ 1,47,696 per sqm, which is
slightly higher than AERA calculated normative benchmark/rates based on Order No. 07/2016-17 dated
June 6, 2016, determined the normative cost for Terminal Buildings.
As per AERA order Clauses (iv) and (v) of the Authority’s Order, in cases where the rates are higher
than the ceiling rates approved by the Authority, the justifications submitted by the Airport Operator
along with details of actual cost incurred are required to be examined by a duly constituted Committee
of Experts, and the final costs are to be adopted based on the recommendations of such committee.
Consultation Paper No. 08/2025-26 Page 76 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE
FIRST CONTROL PERIOD
Further, the ceiling rates are generally applicable to new projects where the works are yet to be awarded,
while in the case of awarded projects the capital costs are required to be examined by the designated
committee. In the present case, the works have already been awarded, and the costs have been incurred
by the Airport Operator. Accordingly, the cost submissions have been examined by the Authority’s
CAPEX consultant, Engineering Projects (India) Limited (EPIL), and based on such examination, the
Authority proposes to consider the capital costs as verified by the CAPEX consultant for the purpose of
the present tariff determination.
Authority also notes that the PTB comprises of equipment’s and building material of richer/advanced
specifications which were not part of the normative cost such as CT Xray/ Dual view Xray integration
with ATRS, full body scanners, IGBC LEED gold certification, self-baggage drop, arrival remote
sensing, automatic tag reader in arrival baggage, advanced BHS with superior features like auto
sortation, E gates with biometric Digi Yatra, PM WANI etc. were also provided. As per Concession
Agreement, the PTB should cater for 80% contact stands. Accordingly, the per sqm. cost is found to be
reasonable.
Therefore, Authority proposes to consider the cost of PTB as mentioned below:

It is further noted that the land development cost of ₹ 881 crore also included ~₹ 34 crore towards
unawarded works. The break-up of ₹ 34 crore included landscaping works of ₹ 11.67 crore and rest ₹
22 crore for change orders in various existing contracts. The details are as below:
a) Landscaping works
NMIAL has recently awarded two contracts for landscaping works with total amounting to ₹ 11.67
crore and the details are as below:
i. Landscaping work (Pkg-3, EMAR) to M/s Grotech Landscape Development Private Ltd of ₹
7.85 crore
ii. Supply of plants & plants supplements for landscaping works to M/s Grotech Farms &
Nursery of ₹ 3.82 crore
Thus, an amount of ₹ 11.67 crore has been considered towards landscaping works.
b) The balance ₹ ~22 crore as claimed against change orders in various existing contracts is not
proposed to be considered, since no details submitted for its review & acceptance. Therefore, the
differential amount of ₹ 22 crore is still unawarded and thus disallowed. However, the same shall
be considered on actual incurrence basis.
The cost of landside development works has been duly analysed by Authority through its independent
consultants based on CPWD PAR, DSR & Market rates. Hence the proposed cost for landside
development works has been considered as ₹ 859 crore.

The unawarded works of ₹ 35 crore toward airport operational equipment and vehicles and cost of ₹ 53
crore towards change order are further elaborated below.
1. Airport operational equipment & vehicles
Authority notes that, in support facility-1 under non-EPC works, an amount of ₹ 59 crore has already
been considered in the CAPEX against “Airside operational equipment’s & vehicles”. Thus, it’s an
additional requirement and not yet awarded. Therefore, additional requirement of ₹ 35 crore against
“Airside operational equipment’s & vehicles” has not been considered & would be considered on
actual incurrence.
2. Change orders in various existing contracts
NMIAL has submitted ₹ 53 crore against change orders in various existing contracts under non-EPC
works and the same has not been considered, based on following:
a) No details/break-up submitted for review & acceptance.
Consultation Paper No. 08/2025-26 Page 79 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE

I - Fuel Farm & Fuel Hydrant System
In line with operational requirements for phases I and II, NMIAL has developed a dedicated Fuel
Farm with a total ATF storage capacity of 24,000 KL, along with an underground fuel hydrant
network designed to supply fuel directly to all aircraft stands, ensuring safety, operational
reliability, and efficiency in refueling processes.
During the development of phases I and II, it is envisaged that NMIA will receive ATF through a
dedicated pipeline and via tank truck deliveries to the Fuel Farm. The stored fuel will be
accommodated in four ATF storage tanks, each with a capacity of 6,000 KL, supported by an
integrated pipeline receipt system. Additionally, the facility includes two underground tanks of 100
KL each for storing Sustainable Aviation Fuel (SAF), which can be blended with ATF as required.
With these additions, the total storage capacity for phases 1 & 2 amounts to 24,200 KL.
For the ultimate development phase, the peak ATF demand has been estimated at 2,300 KL/hour.
To meet this requirement, the project includes a 14.19 km fuel hydrant pipeline network, with pipe
diameters ranging from 24 inches to 12 inches serving as the main header and subloop lines. A 24-
inch pipeline connection has also been reserved for future expansion.
A brief detail of ATF is as below:
• Outright Purchase (5700 KL): Rate per KL (Jet A-1) @ ₹ 62,847 per KL
(i) Tank soaking- 2,400 KL
(ii) FF pieline soaking- 300 KL
(iii) Hydrant line soaking- 3,000 KL

During the site visit by Independent Consultants in July 2025, while there was a provision of 5 fuel
tanks in the fuel farm system proposed by NMIAL, but only 4 tanks were found to be installed.
Accordingly, the price implication of 1 fuel tank along with its accessories which worked out to ₹
42 crore as per original agreement has been proposed not to be considered. A clarification from the
Airport operator was also sought by the CAPEX consultant.
In this regard, NMIAL has submitted a letter dated December 04, 2025, by M/s NCC (executing
contractor), mentioning that cost in BOQ pertains to 4 above ground ATF tanks only and that 5
tanks mentioned in BOQ was a typo error. Further, Authority has examined the submission of
Airport operator and directed Airport operator to submit final payment details during stakeholder
comments, to enable Authority to take a view on the matter.

Consultation Paper No. 08/2025-26 Page 86 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE
FIRST CONTROL PERIOD
EPC Contract – 2. The EPC Contract – 2 was executed between NMIAL and EPC contractor on
August 31, 2019, as per which the time for completion of works was 940 days from Notice to
Proceed.
CIDCO, amongst its obligations, was required to achieve the excess hill cutting and disposal
outside NMIA boundary by May 31, 2022, for NMIAL to achieve the Scheduled Completion Date
and COD for phases I and II earlier planned for December 2024. However, CIDCO’s hill cutting
works were completed on March 21, 2024, and thereafter other subsequent works including
removal of undulations, etc. were completed by June 2024.
NMIAL has submitted that due to the hill cutting works carried out by CIDCO on the NMIA site,
frequent stoppages were caused in its works which disrupted the continuity and hindered the Airport
development works to be undertaken by the EPC contractor. The EPC contractor had thus submitted
blasting/idling claims to NMIAL which included the following aspects.
• Idling of Workmen / Productivity Loss
• Transportation of Workmen
• Idling of Plant & Machinery
• Additional Workmen Sheds
NMIAL had agreed to the claim amount of ₹ 50 crore plus GST based on deliberations and
discussion with EPC contractor as one time settlement against the blasting/idling claims as shown
below.

and administrative costs necessary for project initiation and early-stage development activities. The key
cost components include:
• Salaries, wages, and bonuses of NMIAL staff
• Professional charges, including fees paid to external consultants
• Travel and conveyance expenses
• Manpower service charges
• Depreciation and amortization of IT assets
• Legal and statutory expenses
• Fees, subscriptions, and membership charges
• Rent and infrastructure usage charges
• Miscellaneous administrative and operational costs
The Authority through its Independent Consultants notes that as per the certification provided by the
Chartered Accountant for this expenditure of NMIAL, the actual expenditure incurred towards pre-
Consultation Paper No. 08/2025-26 Page 89 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE

III. Preliminaries
NMIAL has submitted the preliminary expenses of ₹ 172 crore, which comprise a range of activities and
essential preparatory work required for project mobilization and operational readiness such as:
• Establishment of NMIAL project office
• Site enabling works such as site office setup, access road development, construction power
substations and utilities
• Perimeter fencing
• IT infrastructure (desktops, laptops, software, licenses, etc.) for office and site usage
• Geotechnical investigations and various site surveys
• Engagement of specialized consultancy services (e.g., ORAT)
The Authority notes that cost of ₹ 59 crore is related to the construction of the NMIAL project office,
which was considered under soft cost by NMIAL. Since the facility constitutes a permanent structure, it
is proposed to reclassify this expenditure under hard cost. Accordingly, total preliminaries expenses
including this cost would be now ₹ 113 crore.
Excluding the cost pertaining to project office, other components under preliminaries totaling ₹ 113
crore include the following:
a. ₹ 67 crore – Towards site enabling works, already executed.
b. ₹ 30 crore – Towards ORAT consultancy services awarded to M/s Munich Airport International
GmbH.
c. ₹ 16 crore – Provision kept for balance ORAT services which is yet to be awarded. Further,
these services are essential for operational readiness hence considered. The final awarded cost
would be considered at the Tariff Order stage.
The Authority, through its Independent Consultants has reviewed the above cost of ₹ 113 crore, and
found it to be reasonable. Accordingly, the Authority proposes considering preliminary expenditure as
follows:

NMIAL Project office
The cost of ₹ 59 crore towards development of project office has been analysed and it is noted that
the project office complex accommodates the planning, design, and construction departments of
NMIAL and temporarily houses the corporate and operations departments, which will later be
relocated to their permanent facility in the administration building.
Establishing a permanent project office is essential for managing ongoing expansion and operational
oversight. The project office is a G+2 permanent structure, complemented by a G+1 staff facilitation
centre, developed on a total plot area of 11,936.68 sqm with a constructed area of 5,766 sqm. Given
its role as a long-term operational facility supporting the airport’s phased development, the project
office has been classified under hard cost.
The Authority through its Independent Consultants has examined the awarded cost based on CPWD
PAR, DSR & Market rates and found ₹ 59 crore pertaining to project office as reasonable.
IV. Insurance & permits
NMIAL has submitted a cost of ₹ 68 crore towards expenditure under insurance & permits, incurred
towards various statutory and regulatory requirements essential for project execution. This includes
premium payments for CAR (Contractors All Risk) insurance policies, charges for obtaining CTE
(Consent to Establish) approval from MPCB, water connection fees, payments related to the 33 kV
GIS feeder, stamp duty charges, and processing fees paid to multiple local authorities for securing
mandatory clearances and approvals.

I. Allotment of land
As part of the CNS-ATM infrastructure requirements, land has been allotted to AAI for the
installation of ASR-1 (Airport Surveillance Radar) and DVOR (Doppler VHF Omnidirectional
Range) systems. The land allotted pertains to additional land allotted by CIDCO beyond 1,160 Ha of
land allotted earlier for airport development. Hence, CIDCO has asked for a payment of ₹ 60 crore
from NMIAL, towards additional land allotted to AAI for ASR-1 and DVOR. The payment asked by
CIDCO for additional land has not been considered, due to the following reasons:
a) Payment has not been made yet.
b) The term of payment of lease premium is not defined
c) The treatment of cost towards the additional land parcel, should be in line with 1,160 Ha of
land, which was provided earlier, free of cost
d) The ASR-1 has been scheduled in phase 3 of airport development.
Therefore, based on above ground, the cost pertaining to allotment of additional land for ₹ 60 crore
has not been considered.
II. Concession fee and one-time pre-operative expenses
NMIAL is required to pay ₹ 110 crore towards one-time pre-operative expense to CIDCO. In addition,
NMIAL is also required to pay ₹ 40 crore (calculated for period of 8 years effective from Appointed
Date of July 7, 2018, till COD of December 25, 2025, for an amount of ₹ 5 crore per Concession
Year) in accordance with the obligations stipulated under the Clauses of the Concession Agreement,
reproduced below:
Consultation Paper No. 08/2025-26 Page 93 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE
FIRST CONTROL PERIOD
• Clause 25.2.1 “The Concessionaire shall pay Rs. 110,00,00,000/- (Rupees One Hundred Ten
Crore) towards pre-operative expenses incurred by the Authority on the Project till the execution
of this Agreement”
• Clause 25.2.2 “The pre-operative expenses shall be paid by the Concessionaire to the Authority
as a one-time lump-sum amount within 30 (thirty) days of the Phase I COD”
• Clause 26.1 “In consideration of the grant of Concession, the Concessionaire shall pay to the
Authority by way of concession fee (“Concession Fee”), the following amounts to the Authority
on annual basis”
• Clause 26.1.3 “The Concession Fees shall be payable in advance within 7 (seven) days of the
commencement of each Concession Year during the Concession Period”
• Clause 1.1 Definitions: ““Concession Year” means each period of 1 (one) year, commencing
from the Appointed Date and ending on the expiry of 365 days for all years except the leap year
and 366 days for a leap year, provided that such period shall end on the Transfer Date for the
last Concession Year”
Accordingly, the Authority notes the stipulations for the payment of one-time pre-operative expenses
and Concession Fee as the Concession Agreement and thus proposes to consider the amount of ₹ 150
crore towards payment to CIDCO.
III. Building Approvals
NMIAL has submitted ₹ 150 crore towards building approvals which pertain to statutory charges paid
for obtaining mandatory clearances required for project execution and commissioning. This includes
costs associated with securing the:
a) Provisional fire NOC
b) Fees for obtaining the commencement certificate (including layout plan scrutiny and building
approval charges)
c) Charges for issuance of the occupancy certificate
d) Vital Urban Transportation Project (VUTP) charges
As per Clause 5.1.7 (a) of the CA which states that “The Concessionaire shall, at its own cost &
expense procure all Applicable permits in conformity with applicable laws”. Further, clause 6.1.2
also states that “ (a)The Authority shall, provide reasonable support and assistance to cause to
procure all Applicable permits required from any Government Instrumentality, at the cost &
expense of the Concessionaire”.
Out of ₹ 150 crore, NMIAL has already paid ₹ 90 crore for various building approvals. However,
~₹ 60 crore cost is yet to be paid against occupancy certificate which includes essential charges
such as drain connection charges, PSIDC charges, infra charges etc. Being statuary and mandatory
compliance and based on the verification of documents by the Independent Consultants as
submitted by NMIAL, an amount of ₹ 150 crore has been considered, as these payments constitute
statutory obligations. Based on the above analysis, Authority proposes to consider as follows:

O – Financing allowances
NMIAL in its submission has stated that it has computed the financing allowance in accordance with
section 5.2.7 of AERA guidelines. As per NMIAL, the computation of financing allowance has been
provided in Table 18.
As per AERA Guidelines, 2011 and the Authority’s principles followed in the recent tariff orders in case
of Greenfield Airports, the Authority proposes to provide for Financing Allowance. The Authority
considers the capital projects that are being commissioned within the First Control Period to be initial
phase of capital expenditure and accordingly financing allowance will be calculated for the Projects
that are capitalized within the First Control Period of the Airport.
The Authority has carried out a detailed review of the Capital Expenditure for both the demonstration
of need and the reasonableness of costs incurred.
The Authority, based on the revised capital expenditure as proposed, has arrived at the financing
allowance by applying the formula as provided under section 5.2.7 of the AERA Guidelines 2011. The
following changes have been made by the Authority in this regard:
• The revised CWIP has been considered in same proportion as submitted by NMIAL for each
financial year. This has been done based on the ratio derived by dividing the total asset
capitalisation submitted by NMIAL and asset capitalisation proposed by Authority.
• For the purpose of Cost of Debt, the Authority has adopted the actual applicable rate of interest.
• The Financing Allowance has been computed considering all assets would be capitalized on 25th
December 2025
The Financing allowance as recomputed by the Authority considering the revised COD is ₹ 2,892
crores. The detailed computations are as per the table below:

Financing allowance has been worked out based on aeronautical assets proposed to be capitalized in First Control Period. Apart
from same, some assets have been proposed on incurrence basis. Accordingly, financing allowance will be recalculated during
true up based on actual aero capitalisation in First Control Period, at the time of tariff determination of Second Control Period.
P - Sustainable / Minor CAPEX
NMIAL had submitted ₹ 464 crore as sustainable/Minor CAPEX to be incurred for the First Control
Period.
The Independent Consultants have analyzed the submissions made by NMIAL regarding minor CAPEX
proposed for the First Control Period as follows:

• 4 no’s CTX machine is already considered currently by
NMIAL out of 27 nos.
• It is proposed to consider only 16 CTX machine against
proposed 8 Full Body Scanner (@ 2.50 crore each) (i.e.,
in Ratio 1:2). Accordingly, a proportionate amount of ₹
73.43 crore (@ ₹ 4.59 crore per CTX machine) only has
been allowed out of ₹ 105.56 crore submitted by Airport
Security 129.00 95.00 operator
• Full body scanner of ₹ 15 crore has been considered
based on Airport operator submission
• Radiological detection equipment of ₹ 5 crore has also
been considered based on Airport operator submission
• Other security equipment’s of ₹ 1.26 crore has been
considered as submitted by Airport operator
• Thus only ~₹ 95 crore (73.43 + 15 + 5+ 1.26) has been
considered and mis. works & contingency amount shall
be allowed on actual incurrence basis.

The Authority notes that NMIAL would be eligible to claim GST Input Tax Credits on procurement of
certain movable property. The Authority expects that NMIAL would properly account for such credits
in its submissions in accordance with Chapter V of The Central Goods and Services Tax Act, 2017 at
the time of true up of the RAB in the Second Control Period. The Authority may examine the accounting
of input tax credits and make necessary adjustments in this regard at the time of determination of tariffs
for the Second Control Period.
The Authority proposes to consider the recommendation of Independent Consultants for the ITC
deduction as per Table 70 above.

5.3.30 The Authority proposes to reduce (readjustment) 1% of the uncapitalized project cost from the ARR /
target revenue as re-adjustment in case any capital project is not completed/ capitalized as per the
approved capitalization schedule. It is further proposed that if the delay in completion of the project is
beyond the timeline given in the capitalization schedule, due to any reason beyond the control of NMIAL
or its contracting agency and is properly justified, the same would be considered by the Authority while
truing up the actual cost at the time of determination of tariff for the next Control Period. The re-
adjustment in the ARR/ target revenue is to protect the interest of the stakeholders who are paying for
services provided by NMIAL and is also encouragement for NMIAL to commission/ capitalize the
proposed assets as per the approved CAPEX plan/ schedule.
5.4 Aeronautical Allocation of CAPEX for the First Control Period
NMIAL Submission
5.4.1 Authority notes that NMIAL has considered aero allocation as 100% for the First Control Period.
Authority’s examination on asset allocation into aero and non-aero
5.4.2 The Authority has obtained the area statement of the terminal building and notes that NMIAL has
designated 25,356 sq.m. for non- aeronautical out of total area of 2,31,354 sq.m. due to which TBLR
Consultation Paper No. 08/2025-26 Page 99 of 202CAPITAL EXPENDITURE (CAPEX), DEPRECIATION AND REGULATORY ASSET BASE (RAB) FOR THE
FIRST CONTROL PERIOD
works out to be 89.04%:10.96%. It was observed that the area allocation towards non-aeronautical
activities at the other PPP airports such as DIAL, MIAL, BIAL and HIAL are much higher than 10%.
Even the IMG norms on passenger terminals recommend the non-aeronautical area allocation to be
between 8% - 12% for any airport, while for bigger airports, i.e., with passenger traffic exceeding 10
million, commercial area could be up to 20% of the overall area. Considering that NMIAL is a newly
established greenfield airport, the Authority believes that it will attract a substantial amount of non-
aeronautical services. For the First Control Period, the Authority proposes a TBLR of 88%:12%.
5.4.3 The Authority proposes to consider land development as a separate line item. Further the Authority is of
the view that land development is utilized commonly for aeronautical, non-aeronautical and other
activities, thus the aeronautical proportion of site preparation & earthworks and land development costs
has been calculated as follows:

6. FAIR RATE OF RETURN (FRoR) FOR THE FIRST CONTROL PERIOD
6.1 NMIAL’s submission on FRoR for the First Control Period
Cost of Equity
6.1.1 NMIAL had engaged an independent consultant (M/s Pwc) to carry out a study on applicable Cost of
Equity (CoE) for Navi Mumbai International Airport. As per the report, the CoE, in accordance with
Capital Asset Pricing Model (CAPM) is in the range of 19.98% to 20.04%. Accordingly, NMIAL has
considered the average of this range i.e. 20.01% as CoE.
6.1.2 The following assumptions for estimating the Cost of Equity have been submitted by NMIAL:
a) The risk-free rate has been computed based on an average of daily yield for 10 years on the 10-year
Government of India security (G-Sec) which is 7.16%.
b) The Equity Risk Premium (ERP) considered is 7.68%, which is calculated using the average of 10
and 20-year ERP from Sensex and Nifty and as per study by Incwert Advisory. The details are as
below:
i. Implied ERP as on March 31, 2023, using Free Cash Flow to Equity (FCFE)
ii. ERP based on relative approach - Sovereign bond default spread (adjusted for equity market
volatility)
iii. Implied ERP as on March 31, 2023, using DDM.
c) The debt/equity ratio is considered as 48:52.
d) Additional CoE alpha of 2.62% has been considered to factor the risks associated with greenfield
airports in the multiple airport system.
6.1.3 NMIAL has submitted the following in its MYTP relating to the risk profile of NMIA:
“It is also important to note that, NMIAL is a Greenfield Airport and there are various risks associated
with it in a multiple airport system, Greenfield Airports have inherent risks relating to construction
period and project execution, liquidity, etc. Accordingly, some additional risk needs to be factored in
while arriving at the betas for such Greenfield Airports. In case of NMIA, there is also a risk from
CSMIA which is in the same city.
With respect to Greenfield Projects, pre-construction risks like, land development works, rehabilitation
& resettlement and connectivity infrastructure and also post construction risk like Airlines willingness
to transfer operations and impact of yield gap on traffic has to be provided while arriving Greenfield
Alpha. While doing so, the independent consultant has considered risks associated with hypothetical
assets of Hydro and Non Hydro Companies.”
6.1.4 Based on the above, the CoE submitted by NMIAL is as detailed below:

Additional greenfield alpha E 2.62%
Modified CoE F= D + E 20.01%
Cost of Debt
6.1.5 NMIAL has submitted that it has availed a Rupee Term Loan (RTL) of ₹ 12,770 crore for phase I and
II of the project, out of total project cost of ₹ 20,380 crore resulting in a Debt: Equity ratio of 63:37.
Further, NMIAL has submitted that it has planned RTL of ₹ 21,463 crore for phase III out of the
estimated project cost of ₹ 32,556 crore, including minor CAPEX of ₹ 464 crore for First Control
Period, with a Debt: Equity ratio of 65:35.
6.1.6 NMIAL has submitted that in order to fund the project cost of phase I and II, NMIAL has tied up loan
with consortium of banks with SBI as the lead bank. The facility has been taken for 23 years, which
includes a construction period of 3 years, 1 year moratorium and 19 years of repayment. As per the
facility agreement read with addendum submitted on August 1, 2025, NMIAL shall repay the 100% of
facility in 76 quarterly structured instalments commencing from quarter ending March 31, 2027, with
last instalment due on December 31, 2045. The rate of interest shall be 9.25% till June 14, 2025, from
June 15, 2025, the applicable interest rate shall be 170 bps above 6M SBI MCLR till COD. For post
COD, the applicable interest rate shall be SBI 6-month MCLR and spread of 155 bps for ECR “A”.
6.1.7 NMIAL has submitted that CIDCO has been releasing the soft loan in tranches as per the cost of pre-
development works being incurred. As per the reconciliation statement till October 25, 2025, CIDCO
has released an aggregate amount of ₹ 3,747 crore towards the soft loan including equity of ₹ 430 crore.
6.1.8 As per the Clause 12.9.6 of the CA, no interest payment is specified (and therefore, not applicable) for
the soft loan extended by CIDCO, if repayment commences from the 11th year of the appointed date
(which is July 7, 2018) in the manner specified in the said clause. Subsequently, NMIAL requested
CIDCO for deferment from repayment of soft loan as provided in Clause 12.9.6 of the CA. CIDCO
vide letter dated May 8, 2018 approved the request of NMIAL i.e. deferment of repayment of soft loan
from 11th year from the appointed date to 21st year from phase I and II COD:
“… the Concessionaire shall ensure that the net present value of the Soft Loan remains the same as the
net present value of the Soft Loan as of the Appointed Date calculated by discounting at the rate of 2%
above the Bank Rate.”
As per the MYTP submission, the bank rate as on appointed date of July 7, 2018, was 6.50%. Thereby,
2% above the bank rate works out to 8.50%.
In addition to the above, Clause 2.2.9 of the MoU signed between NMIAL and GoI mandates interest
on soft loan to be considered while calculating FRoR which states:
“ 2.2.9 Asset forming part of the Pre-development Works and financed by Soft Loan shall be considered
as part of the capital expenditure for the purposes of the determination of the Aeronautical Charges.
The interest on Soft Loan, pertaining to Pre-development Works inside and outside the Site to the extent
Consultation Paper No. 08/2025-26 Page 108 of 202FAIR RATE OF RETURN (FRoR) FOR THE FIRST CONTROL PERIOD
it is part of the mandated cost under the Concession Agreement, will be taken into calculation of FRoR
at:
a) 0% cost of capital, if no interest is payable/ paid by the Concessionaire to the Authority on the Soft
Loan, and
b) the applicable rate of interest as may be payable/ paid by the Concessionaire to the Authority on
exercise of optional deferment of the linkage date for the repayment of the Soft Loan as per proviso
(ii) to Clause 12.9.6 of the Concession Agreement to keep the net present value of the Soft Loan as
on the Appointed Date, for determination of the Aeronautical Charges.”
Since NMIAL has opted for deferment for repayment of soft loan to CIDCO, the interest as mentioned
above is a mandated cost as per the terms of MoU which shall be considered while calculating FRoR.
6.1.9 Summary of Debt availed by NMIAL as provided in MYTP submission is as follows:

6.2 Authority Examination Regarding FRoR for the First Control Period
Cost of Equity
6.2.1 The Authority notes that in the past, it had commissioned independent studies for the evaluation of cost
of capital separately, in case of PPP airports, namely DIAL and MIAL in December 2019, BIAL in June
2020, HIAL in December 2020, and CIAL in March 2021 through a premier institute i.e., IIM-
Bangalore (IIM-B).
6.2.2 The Authority understands that asset beta measures the market risk of a project or company without the
impact of debt. To compare the study undertaken by NMIA and previously by IIM-B, the Authority,
through its independent consultant, has made a comparison between the asset beta as per the study
report of NMIA with the independent studies referred above. It was noted that the asset beta for the 5
airports was as below:

IIM-B study MIAL DIAL BIAL HIAL CIAL
Asset beta based on proximity score
0.59 0.57 0.56 0.57 0.57
weights of comparable set
The asset betas for the five (5) PPP airports were in the range of 0.560 to 0.590, whereas the asset beta
as computed by NMIA was in the range of 0.785 to 0.790. The list of airports considered for
computation of asset beta in both study reports are enumerated in the table below:

6.2.3 The Authority notes the following differences between the two study reports:
a) In the study done by IIM-B for the 5 airports, comparable airports were shortlisted on the basis of
proximity to subject airport on aspects like revenue till structure, ownership structure and scale of
operations and thus Mexican and Italian airports were excluded from the comparison. However, in
the report for NMIA, Mexican and Italian airports have been considered in the peer group.
b) The Authority notes that the risk-free rate of return considered in the study on CoE for NMIA was
based on the yield of a 10-year G-Sec (2014-2023), which was 7.16%. The Authority has reviewed
the latest available data and the yield on the 10-year G-Sec par yield (FBIL) stands at 6.40% and
7% as published by the Reserve Bank of India (RBI) on April 8, 2025, and July 25, 2025,
respectively.
6.2.4 The Authority has examined the rationale submitted by NMIA for considering incremental risk
premium alpha (α) over the CoE attributable to the pre-construction risks/greenfield nature of the asset.
The Authority’s analysis is as follows:
Table 87: Rationale submitted by NMIAL for inclusion of incremental risk premium and the Authority’s
analysis of the same
S No Excerpts from NMIA COE Report Authority’s analysis
1 Land development works The Authority notes that most of the works
• Cutting of hills in and around the site up mentioned, like cutting of hill, diversion channel for
to level of +8 meters above MSL Ulwe river, re-routing of High Voltage Transmission
• Ground improvement works lines, etc. were part of the pre-development works to

S No Excerpts from NMIA COE Report Authority’s analysis
• Re-routing of extra High Voltage The Authority notes that the cost for land
Transmission lines development works has been considered as soft loan
• Excess rock disintegration and and has to be paid in 5 equal installments beginning
transportation of 140 m3 volume from the 21st anniversary of the phase 1 COD such
that entire soft loan is repaid to the CIDCO by the
25th anniversary of the phase 1 COD, while ensuring
the net present value of the soft loan remains the same
as of the appointed date by discounting it at the rate
of 2% above the bank rate.
Since some time and cost over-run has been
considered / approved in CAPEX (RAB) in the form
of cost escalation, the Authority notes that if the same
is considered as part of incremental risk, it may lead
to duplicity. Additionally, no further risk is envisaged
on this account. Therefore, the Authority proposes not
to consider this risk.
2 Rehabilitation and Resettlement The Authority notes that rehabilitation and

3 Connectivity infrastructure The Authority notes that NMIA is strategically
• Strong connectivity to the new airport located between the 8-lane Amra Marg (west) and 4-
from Mumbai city and adjoining areas lane NH-4B (east) in Navi Mumbai. The airport is
essential to materialization of envisaged also close to the Mumbai Pune Expressway (Sion-
traffic growth Panvel Highway), connected to it by Amra Marg. The
• However, the recent opening of the recently commissioned MTHL, a 22-km long bridge,
Trans-Harbour link between the two across the Thane creek from Sewri to Ulwe, now
cities is expected to play a mitigating directly connects NMIA to South Mumbai. Thus the
role Authority does not envisage any risk on account of
connectivity.
4 Airline willingness The Authority notes that considering the capacity
• Airlines should be willing to operate constraint at CSMIA, airlines wanting to cater to the
flights from Navi Mumbai Airport increasing aviation demand in MMR will have to
explore operations from NMIA. Additionally, with
the upcoming closure of terminal 1 of CSMIA, some
traffic will have to shift to NMIA, adding to the
unserved traffic of MMR. Thus, the Authority does
not envisage any risk on account of lack of airline
willingness to operate from NMIA.
5 Impact of yield gap on traffic The difference in yield has already been factored as
• YPP at NMIA expected to be much part of traffic projection at NMIA. Additionally, with
higher than CSMIA in initial periods –

discouraging traffic uptake at the new the capacity constraint at CSMIA, additional aviation
airport traffic will move to NMIA.
6.2.5 Authority has noted the various risk factors listed out by the airport operator. It is also noted that the
airport operators in India have certain inherent advantage and protections built into the tariff
determination process and airport management, some of which are highlighted below:
a) The tariff determination methodology incorporates adequate return on airport operator’s gross fixed
assets investments, as well as O&M expenses and other building blocks in setting tariff.
b) The tariff determination mechanism also ensures the true up of certain building blocks on actual
basis in the tariff determination process.
c) There is a well-documented, stable, publicly notified regulatory regime for tariff determination and
the proceedings are conducted in a transparent manner in compliance with the AERA Act and other
relevant guidelines.
d) The GoI, through the MoCA and various regulatory agencies, provides adequate support and
guidance on all operational, safety, airline, connectivity and stakeholder related matters.
e) Similarly, the relevant State Government and its nominated nodal agency help the Airport Operator
by allotting land on concessional rates/free of cost in many of the cases and take responsibility for
ensuring multi-modal connectivity to the airports.
6.2.6 The Authority notes that the CoE for the purpose of determination of FRoR has to be fairly consistent
in case of PPP airports across India as the factors considered by the independent study in CAPM
formula such as risk-free rate, market premium are in Indian context and do not vary significantly
among the airports as these are operated under similar environment. NMIA is comparable to the other
PPP airports which have been used as reference point for computation of CoE.
6.2.7 The Authority expects NMIAL to bring efficiency in its operational and financial management of the
concerned airport, in line with the other PPP airports. The Authority is of the view that the studies
sponsored by the respective airport operators always have an inherent conflict of interest. Thus, these
studies have to be undertaken by an independent and reputed agency. In this context, the study
conducted by IIM-Bangalore engaged by AERA to determine cost of equity for representative airports
would be the basis of determining FRoR.
6.2.8 It was observed that the CoE was higher than the range established by AERA’s CoE study conducted
by IIM-B for five airports of 15.18%.
Table 88: Average CoE of 5 airports as per IIM-B study

Cost of Equity 15.13% 15.41% 15.03% 15.17% 15.16% 15.18%
6.2.9 The Authority notes that the average CoE of 15.18% as estimated from the IIM-B study was considered
for the First Control Period of MoPA, Goa, which was also a greenfield airport. NMIA being a
greenfield airport like MoPA, Goa, and considering that private sector participation is expected to bring
Consultation Paper No. 08/2025-26 Page 113 of 202FAIR RATE OF RETURN (FRoR) FOR THE FIRST CONTROL PERIOD
in cost efficiencies, based on the above reports, the Authority proposes the CoE of 15.18% for NMIA
for the First Control Period.
Cost of Debt
6.2.10 As per details submitted, NMIAL has tied up the funds with:
a) SBI Rupee Term Loan (RTL) to the tune of ₹ 12,770 crore to be repaid in 76 quarterly instalments
commencing from quarter ending March 31, 2027, with last instalment due on December 31, 2045.
• Pre COD: Rate for SBI term loan considered as per loan agreement. The MYTP submission
has considered “effective rate of interest as interest is payable on monthly basis”.
• Post COD: SBI term loan rate considered as 6-months MCLR of SBI + 155 bps as provided in
loan agreement.
b) Inter Corporate Deposit (ICD) from AAHL to the tune of ₹ 3,000 crore to be repaid only once the
repayment of senior lender’s loan is made.
• The ICD agreement between NMIAL and AAHL mentions: The interest payable by NMIAL
on the outstanding loan amount shall be calculated at the interest rate which is lower of:
o annualized 9.64% rate of interest;
o such other interest rates which is lower than the interest rate charged by the senior lenders
under the financing agreements;
o such other interest rate equal to or less than 5% above the bank rate.
However, MYTP considers rate of interest same as senior debt.
c) CIDCO to the tune of ₹ 3,747 crore out which ₹ 430 crore shall be considered as Authority’s capital
infusion to be repaid from 21st anniversary of CoD of phase I and II till 26th anniversary.
SBI RTL
6.2.11 The Authority notes that the airport operator has considered cost of debt for SBI RTL at 10.45% basis
SBI 6-months MCLR of 8.90% + 1.55% spread basis “A” rating for the First Control Period as given
in loan agreement.
6.2.12 Authority also notes that as per the addendum to facility agreement for SBI RTL dated June 16, 2025,
the revised terms applicable are as follows:
a) Debt repayment of RTL has been postponed by one year and is to be repaid in 76 quarterly
instalments commencing from quarter ending March 31, 2027 with last instalment due on
December 31, 2045
b) Pre-COD rate of interest of 9.25% is applicable till June 14, 2025. The revised rate of interest post
June 15, 2025, till COD shall be 170 bps above 6-months MCLR of SBI.
c) Post COD rate of interest as per addendum is same as original facility agreement i.e. 6-month
MCLR of SBI + 155 bps.
Therefore, the Authority proposes to consider the above revised terms.
Consultation Paper No. 08/2025-26 Page 114 of 202FAIR RATE OF RETURN (FRoR) FOR THE FIRST CONTROL PERIOD
6.2.13 Based on the above, the Authority proposes to consider the following:

Soft Loan
6.2.18 Authority notes that NMIAL has considered cost of debt of soft loan into calculation of FRoR @ 8.50%
(Bank rate as + 2%) as per Clause 12.9.6 of CA and clause 2.2.9 of MOU (repayment deferment).
6.2.19 Based on the revised cost towards pre-development works submitted by NMIAL, the amount of soft
loan is revised to ₹ 3,747 crore. However, the same is under reconciliation and ₹ 3420 crore has been
considered as Soft loan at this stage.
Consultation Paper No. 08/2025-26 Page 115 of 202FAIR RATE OF RETURN (FRoR) FOR THE FIRST CONTROL PERIOD
6.2.20 The relevant clauses of the CA pertaining to soft loan are referred in chapter 5, the key terms in relation
to the soft loan are summarized and reproduced as below:
a) Clause 12.9.1: The pre-development works up to an amount of ₹ 3,420 crore shall be deemed as soft
loan
b) Clause 12.9.2: Out of the soft loan, ₹ 430 crore shall be considered as the Authority’s equity capital
infusion in the concessionaire. The soft loan amount shall be reduced accordingly while determining
repayment obligations.
c) Clause 12.9.3: Any additional cost incurred by the Authority for implementing pre-development
works (beyond the soft loan limit) shall be paid separately in accordance with the LDS Agreement(s).
Such additional amounts shall not form part of the soft loan.
d) Clause 12.9.6: Soft loan shall be repayable as follows:
i. ₹2,358 beginning from 11th anniversary of the appointed date after adjustment of equity.
ii. Balance amount of ₹1,062 of the soft loan after adjustment of equity, beginning from the
16th anniversary of the appointed date.
However, deferment option is also available to NMIAL and in case of exercise of this option NMIAL
is required to pay such amount, which is equivalent to the net present value of soft loan, as of the
appointed date, arrived at by discounting it at the rate of 2% above the bank rate
6.2.21 Authority notes that NMIAL has been granted deferment for repayment of soft loan vide letter dated
May 8, 2018, by CIDCO. As per deferment letter, concessionaire is required to repay the soft loan, after
reducing equity portion of ₹ 430 crore by CIDCO, in 5 equal instalments beginning from the 21st
anniversary of the phase I COD, such that entire soft loan is repaid to the authority by the 25th
anniversary of the phase I COD or the date, following six months after the senior lender have been fully
repaid, whichever is earlier.
6.2.22 The Authority proposes to consider ₹ 2,990 crore towards soft loan after deducting equity portion of ₹
430 crore as specified in CA for calculation of average debt.
6.2.23 Authority also notes that as per clause 2.2.9 of MOU between GoI and NMIAL that the interest on the
soft loan, pertaining to pre-development works, shall be taken into calculation of FROR (Fair Return
on Regulatory Asset Base) at Bank rate + 2% payable by the concessionaire to the Authority.
6.2.24 For soft loan, the authority proposes to consider soft loan as part of calculation of cost of debt and
FRoR at the rate of Bank rate + 2%, which is 5.5% (accessed as on February 4, 2026) + 2% i.e. 7.5%.
6.2.25 Based on above, the Authority proposes to consider the following soft loan for calculation of average
cost of debt:

the cost of debt of 9.57% for the computation of FRoR.
Fair Rate of Return
6.2.28 The Authority is of the view that the Airport shall bring in further efficiencies in its cost of borrowing
in order to reduce the interest rates. This suggestion is also in keeping with the spirit of PPP whereby it
is expected that the financial strength of PPP airports is maintained at an optimal level and their cost of
capital is within reasonably allowable limits. NMIAL should avail the synergies and benefits owed to
it by its strong shareholding and balance sheet of its Parent companies and therefore work towards
bringing down the cost of debt to the same level as other PPP airports.
6.2.29 The Authority believes that PPP airports have the scope of bringing in better efficiencies in financial
and operational management of an Airport which would reflect in its overall cost of operations and
lower FRoR.
6.2.30 Based on the above, the Authority proposes to consider the following FRoR for the First Control Period
for NMIA as:
Table 94: FRoR proposed by the Authority for the First Control Period

7.1 NMIAL’s Submission on Inflation for the First Control Period
7.1.1 NMIAL has considered inflationary increase towards operating and maintenance expenses and non-
aeronautical revenues at Navi Mumbai International Airport for the First Control Period.
7.1.2 For the purpose of inflation, NMIAL has quoted RBI forecaster survey 91st round dated December 6,
2024 - Mean WPI (all commodities) for FY 2025-26 as 3%.
7.1.3 NMIAL has considered inflation as 5% for all years in the First Control Period, from FY 2025-26
onwards, while projecting both CAPEX and operating expenditure wherever applicable.

Inflation 5.00% 5.00% 5.00% 5.00% 5.00%
7.2 Authority’s examination regarding inflation for the First Control Period
7.2.1 The Authority notes NMIAL’s submission on inflation to be considered during the First Control Period.
The Authority proposes to consider the recent results of the “Survey of Professional Forecasters on
Macroeconomic Indicators: Round 98th” released on February 6, 2026, by the Reserve Bank of India
(RBI).
7.2.2 Accordingly, the Authority proposes to consider the mean of WPI inflation forecasts (All commodities)
for FY 2025-26 and FY 2026-27 as given in the 98th Round of Professional Forecasters on
Macroeconomic Indicators (February 6, 2026) of RBI.
7.2.3 Further the Authority assumes that the inflation rate would be stable and remain constant from FY 2026-
27 till FY 2029-30. Accordingly, the following table shows the inflation rates as proposed by the
Authority for the First Control Period.

Control Period:
7.3.1 To consider inflation for the First Control Period for NMIA as per Table 96
Consultation Paper No. 08/2025-26 Page 119 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
8. OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
8.1 NMIAL’s submission regarding Operation and Maintenance expenses for the First
Control Period
8.1.1 NMIAL has submitted its projections for Operation and Maintenance (O&M) expenses for the First
Control Period, covering costs towards manpower, utilities, repairs and maintenance, insurance,
information technology and digitisation, administrative and other general expenses. The projections
have been prepared in accordance with the obligations of the NMIAL under Article 17 of the
Concession Agreement, which sets out requirements relating to the operation, maintenance and
management requirements of the Airport.
8.1.2 NMIAL has considered the following key drivers for projecting O&M expenses for the First Control
Period:
• Base year: O&M expenses for FY 2025-26, being the first year of operations, are estimated based
on various parameters on a zero-based cost budgeting approach, benchmarking with comparable
airports and the operational experience of the promoter group in airports management.
• Inflationary increase: An annual inflation rate of 5% has been considered for projecting O&M
expenses for all years in the First Control Period, commencing, wherever applicable.
• Upcoming expansion at NMIA: As set out in chapter 5 of this Consultation Paper, NMIAL
proposes to undertake capacity expansion at NMIA from 20 to 50 MPPA during the First Control
Period. In respect of phase III expansion, NMIAL has taken Y-o-Y increase of ~87%, considering
operationalization of terminal 2 from mid of FY 2029-30, while projecting O&M expenses.
Table 97: Details of increase in the terminal building area projected by NMIAL

2029-30 231,393 400,000 631,393 173.00%*
(*) T2 is proposed to be operational from October 2029. Therefore, for the projection of expenses for FY 2029-30, NMIAL
has assumed an increase in area from mid of FY 2029-30 onwards i.e. 87% (50% of 173%)
Considering the proposed expansion of the terminal building area as mentioned in the table above,
NMIAL has projected a proportionate increase in utilities, rates & taxes, and other operating
expenses. Expenditure on manpower, administrative, information technology and security
functions has been projected with increase in manpower requirements.
8.1.3 Based on the assumptions and drivers set out in paragraphs 8.1.1 and 8.1.2 above, NMIAL has
submitted a summary of total O&M expenses for the First Control Period. The year-wise details of such
O&M expenses are presented in Table 98 below.

Table 98 for the First Control Period:
A. Manpower expenses
8.1.6 NMIAL has estimated total manpower costs for the First Control Period based on projected employee
costs, including salaries, wages and bonuses, contributions to Provident Fund (PF) and gratuity. The
projections have been prepared using a bottom-up approach, wherein NMIAL has estimated
department-wise manpower requirements at the airport, taking account the grading structure of
employees. Based on the proposed grading structure, prevailing median salary levels have been
considered for each category of employees, and the corresponding manpower cost has been derived.
An annual escalation of 10% in average salary cost per employee has been assumed for projecting the
manpower costs for the First Control Period. Further, NMIAL has factored incremental manpower
requirements arising from the proposed expansion and increase in scale of airport operations during the
First Control Period. The department-wise manpower details submitted by NMIAL is set out in Table

the expiry or termination of the said appointment, the Authority shall appoint an Independent Engineer
for a further term of 3 (three) years in accordance with the provisions of Schedule M, and such
procedure shall be repeated after expiry of each appointment.
23.3.1 The remuneration, cost and expenses of the Independent Engineer shall be paid by the Authority,
and all such remuneration, cost and expenses shall be reimbursed by the Concessionaire to the
Authority within 15 (fifteen) days of receiving a statement of expenditure from the Authority.
23.3.2 Any amounts paid to the Independent Engineer shall be a pass-through for the determination of
the Aeronautical Charges by AERA.”
8.1.42 Accordingly, the IE is to be appointed initially until phase I COD and thereafter for every 3 years till
the end of concession period of 30 years. The cost of the IE shall be paid by CIDCO and that shall be
reimbursed by NMIAL to CIDCO. The cost of IE will be pass-through for the determination of
aeronautical charges by AERA.
8.1.43 In accordance with the above, CIDCO had appointed M/s AECOM Asia Company Limited in
consortium with AECOM India Private Limited as the IE, initially for a period of 4 years with total cost
of ₹ 34.80 crore. This agreement expired on October 28, 2022. Subsequently, CIDCO in mutual consent
with the IE, extended services of the IE up to December 30, 2024, for a lump sum amount of about ₹
20 crore plus GST.
8.1.44 NMIAL has considered the rate of charges for IE services during the operations period at 50% of the
rate during the construction period. Additionally, NMIAL has assumed an annual escalation in cost as
10%. Based on the above assumptions, NMIAL proposes the following cost of IE.

Particulars FY26 FY27 FY28 FY29 FY30 Total
Independent Engineer's fees 5.00 5.50 6.05 6.66 7.32 30.53
N. Digitization cost
8.1.45 NMIAL has submitted that the next phase of growth in the aviation sector will be dependent on digital
transformation / technology intervention where an airport operator can provide end to end services to
the consumers (origin to destination) on single platform which will result in enhanced consumer
experience and more satisfaction.
Consultation Paper No. 08/2025-26 Page 131 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
8.1.46 NMIAL has submitted that it neither has bandwidth nor expertise to undertake digitalization of airport
experience. The same will have to be done with the help of industry experts in the digital field. Building
specific manpower for this field will have challenges and considering pace at which digitisation is
required to be adopted, timelines are also not conducive. Hence NMIAL, through the competitive
bidding process will select another entity which can help it to embark on this journey of digitalisation.
The costs for digitisation estimated by NMIAL are as below:
Table 114: Digitisation cost as submitted by NMIAL for First Control Period
(in ₹ crore)
Particulars FY26 FY27 FY28 FY29 FY30 Total
Digitisation cost 110.00 121.00 133.10 146.41 161.05 671.56
8.1.47 NMIAL has considered annual escalation of 10%.
O. Financing charges and others
8.1.48 Financing charges include not limited to bank charges for routine operations, debt arranging charges,
processing fees and upfront fees payable to lenders, documentation charges, and various agencies. As
per industry trade practice, the upfront fees range from 1.50% to 2.50% depending on the size and
complexity of the transaction. Accordingly, NMIAL has assumed 1.50% of the debt amount as
financing charges.
8.1.49 NMIAL has also tendered a Performance Bank Guarantee to CIDCO as mandated under Clause 9.1.1
of the CA as follows:
“The Concessionaire shall, for the performance of its obligations hereunder in respect of Phase I,
provide to the Authority, no later than 60 (sixty) days from the date of this Agreement, an irrevocable
and unconditional guarantee from a Bank for a sum equivalent to Rs. 100,00,00,000 (Rupees One
Hundred Crore) in the form set forth in Schedule F (“Performance Security”). Until such time the
Performance Security is provided by the Concessionaire pursuant hereto and the same comes into
effect, the Bid Security shall remain in force and effect, and upon such provision of the Performance
Security pursuant hereto, the Authority shall release the Bid Security to the Concessionaire.”
8.1.50 Further, on revision of initial phase from phase I alone to phase I & II combined, NMIAL was required
to furnish additional Performance Security of ₹ 110.38 crore to CIDCO as per para 9.1.3 of CA,
reproduced below for quick reference.
The Concessionaire shall provide separate Performance Securities prior to undertaking the
Construction Works for any of the subsequent phases, for an amount equivalent to 2% (two percent) of
the cost approved for such phase by the Senior Lenders of each such phase of the Project. The term
Performance Security as used in this Agreement shall refer to and include all the Performance
Securities to be provided by the Concessionaire for each phase of the Project.
8.1.51 NMIAL has arranged Performance Bank Guarantees from State Bank of India in favor of CIDCO.
Annual fee of 1% (plus applicable taxes) of the Performance Bank Guarantee is to be paid to State Bank
of India (Lender) as per agreed terms.
8.1.52 Additionally, a working capital loan has been assumed at an average cost of debt 10.97% per annum of
average of opening and closing working capital balance. For calculation of working capital

P. Cargo operating expenses
8.1.53 NMIAL has submitted that Clause 18.4 of the CA stipulates the airport operator’s obligations towards
developing, operating and maintaining the cargo facilities.
8.1.54 As per the MYTP submission, NMIAL would outsource all day-to-day operations of the cargo facility
(domestic and international) to an O&M agency for a fee (O&M fees). Based on the cost structure of
cargo operations at other major airports, the airport operator has estimated that O&M Fees would be
based on volume of cargo tonnage processed from the cargo facility and expects it to be about ₹ 8,000
per ton. An escalation of 10% Y-o-Y has been considered for O&M Fee.
8.1.55 NMIAL has submitted that it will appoint supervisory staff and duty managers to oversee the facility
and functioning of the O&M operator on a day-to-day basis. Being a 24*7 facility, NMIAL has
considered three (3) number of supervisors and three (3) number of duty managers in shifts. The average
annual cost per person has been considered ₹ 33 lakh. Total cost has been considered as approximately
2 crore per annum with an escalation of 10%.
8.1.56 In addition to O&M fees, NMIAL will have to bear custom cost recovery charges for the international
cargo facility for sanctioned staff of 116 and 232 for FY 2025-26 and 2026-27 respectively as per
custom regulation circular 02/2021 dated January 19, 2021, and letter dated July 5, 2023, by the
Commissioner of Customs. NMIAL considers that as the volume of cargo increases and achieves the
threshold of exemption criteria, custom cost recovery charges are expected to be exempted from FY
2027-28 onwards.
8.1.57 NMIAL has submitted that as per MoCA directive in 2024, all airport operators are to bear the cost of
deployment of CISF personnel deployed at GA terminal, cargo and MRO. In light of the same, NMIAL
has considered CISF deployment cost while computing the total cost attributable to cargo operations.
8.1.58 Based on the above, the operating cost for cargo facility submitted by NMIAL is as below:

Q. Fuel Farm operating expenses
8.1.59 NMIAL has submitted that Clause 18.3. of the CA stipulates the Airport Operator’s obligations towards
providing necessary fuel infrastructure facilities on an equal/open access basis at the Airport. The
concessionaire shall provide, or cause to be provided, the infrastructure required for the operation of
Fuelling services on equal access basis for all the aircrafts at the Airport in a transparent and non-
discriminatory manner ("Aircraft Fuelling Services"). Such infrastructure shall include tank farms,
common hydrant fuelling systems and associated facilities in accordance with the provisions of this
agreement, applicable laws and good industry practice.
8.1.60 NMIAL has submitted that the day-to-day operations and management of the Fuel Farm would be
outsourced to an O&M agency on a volume linked fee basis (with minimum annual guarantee). The
MYTP submission considers the fees for O&M agency to be ₹ 500 per KL with an increase in rate by
5% per annum.
8.1.61 NMIAL has submitted that it will appoint supervisory staff and duty managers to oversee the facility
and functioning of the O&M operator on a day-to-day basis. Being a 24*7 facility, NMIAL has
considered three (3) number of supervisors and three (3) number of duty managers in shifts. The average
annual cost per person has been considered ₹ 33 lakh. Total cost has been considered as approximately
2 crore per annum with an escalation of 10%.

8.2 Authority’s examination regarding Operation and Maintenance (O&M) expenses for
the First Control Period
8.2.1 The Authority notes the basis and estimation of O&M expenses submitted by NMIAL for the First
Control Period. The Authority notes that NMIAL has projected O&M expenses considering
infrastructure requirements, personnel costs, equipment maintenance, utilities, security measures and
other costs. The Authority has noted that NMIAL has considered all O&M expenses as aeronautical
expenses, without segregation into aeronautical and non-aeronautical expense.
The MYTP submission also does not consider categorization based on Terminal Building Ratio or Gross
Block Ratio. The Authority notes that depending on the nature of services provided or area allocated,
expenses should be segregated as aeronautical or non-aeronautical or common. The Authority has
conducted a detailed analysis of O&M expenses submitted by NMIAL in the following order:
I. Computation of Allocation ratios
II. Examination of O&M expenses and its allocation into aeronautical and non-aeronautical
expenses
Consultation Paper No. 08/2025-26 Page 134 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
I. Allocation ratios
8.2.2 The following ratios have been computed by the Authority for appropriate segregation of expenses into
aeronautical, non-aeronautical and common expenses. Thereafter, common expenses have been further
segregated between aeronautical and non-aeronautical for First Control Period.
Terminal Building Ratio
8.2.3 The Authority notes that about 25,356 sqm. area in the terminal building is considered for non-
aeronautical or commercial activities. This is about 10.96% of the terminal building. The report of the
Inter-Ministerial Group (IMG) on Norms and Standards for Determining the Capacity of Airport
Terminals provides that commercial or retail area normally require 8 – 12% of the overall area and
should be planned and provided accordingly. In bigger airports, i.e., with annual passenger traffic
exceeding 10 million, the commercial area could be up to 20% of the overall area.
8.2.4 The Authority notes that NMIA, while being a bigger airport, is also a greenfield airport. Thus, the unit
area norm of 20% may be too early to consider. However, as NMIAL is already projecting to use
10.96% of terminal building area for non-aeronautical or commercial activities, it may be able to
leverage private sector experience and increase non-aeronautical area to about 12% during the First
Control Period. Therefore, the Authority proposes to consider the terminal building ratio of 88%:12%
as allocation of area towards aeronautical and non-aeronautical activities for the First Control Period.
Gross Block Ratio
8.2.5 The Authority, based on the proposed CAPEX in Table 73 and proposes the Gross Block Ratio for the
First Control Period as presented in the table below.
Table 118: Gross Block Ratio proposed by the Authority for the First Control Period

Employee Head Count Ratio
8.2.6 The Authority notes that NMIAL has considered all manpower expenses as aeronautical in nature.
Based on the nature of services provided by each department, no segregation as aeronautical or non-
aeronautical or common has been provided. As part of its MYTP, NMIAL has submitted department
wise estimation of employee head count proposed to be deployed at NMIA.
Consultation Paper No. 08/2025-26 Page 135 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
8.2.7 The Authority notes that NMIAL has factored in the capacity expansion of phase III in FY 2029-30 and
considered an increase in employee headcount. The Authority after analysing the same has not
considered this projected increase due to reason stated in para 4.2.8.
8.2.8 Authority through its Independent Consultant had sought the actual status of manpower count. NMIAL
vide email dated December 31, 2025, submitted expected manpower of 550 as on March 31, 2026. As
per NMIAL, manpower requirement is expected to increase in future as scale of operations increase
and international operations also start. The department wise manpower is projected to go up to 752 in
FY2026-27 by NMIAL.
8.2.9 On review of the projected number of employees, the Authority notes that the passenger per employee
count in NMIA was in line with other airports whose passenger profile was similar to NMIA.
Table 119: Benchmarking of manpower with other airports
Airport Projected Total Pax in MPPA* Manpower in Nos Avg. Manpower per MPPA
NMIAL 100.12 752 7.51

MIAL 229.17 1152 5.02
BIAL 174.88 1509 8.62
*Based on traffic projections in consultation paper by AERA
Therefore, the Authority proposes to consider the employee head count as submitted by NMIAL for the
First Control Period incorporating a gradual ramp up in manpower. Therefore, it proposes adjusting the
employee count from 550 to 752, effective from March FY 2026 to FY 2030 as per the Table 121 below.
8.2.10 After examining the functions of each department, the Authority is of the view that the duties of
employees listed below extend beyond aeronautical activities and encompass non-aeronautical
activities or overall operations of the Airport. As a result, the Authority proposes reclassification of
these departments as either non-aeronautical or common:

Classification and allocation of O&M expenses
8.2.13 The Authority has classified and assigned the projected O&M expenses into three distinct categories:
aeronautical, non-aeronautical, and common. Further, the common expenses have been allocated into
aeronautical and non-aeronautical categories, based on the established methodology followed by the
Authority across all airports. Presented below is the table illustrating the classification and allocation
of O&M expenses proposed by the Authority in the subsequent paragraphs, into the aeronautical and
non-aeronautical segments for the First Control Period:

II. Examination of O&M expenses and its allocation into aeronautical and non-aeronautical
expenses
8.2.14 The Authority has examined NMIAL’s submission regarding inflationary increase and expansion
increase. Authority’s view on the same are elaborated below.
Inflationary increase
8.2.15 The Authority, on examination of the submission made by NMIAL, notes that inflation of 5% has been
considered by NMIAL. However, the Authority proposes to consider WPI inflation of 0.50% in FY
2025-26 and 3.00% thereafter during the First Control Period, as published in the results of the 98th
round of the Survey of Professional Forecasters on Macroeconomic Indicators released on February 6,
2026.
Phase III expansion increase
8.2.16 The Authority notes that NMIAL in its submission has projected various expenses by considering an
incremental increase factor in FY 2029-30 attributed to the proposed operationalization of phase III.
However, as mentioned in chapter 5 (refer para 5.3.2), phase III capitalisation would be considered on
incurrence basis. Therefore, phase III related expansion expense has not been considered.
Head-wise analysis of various O&M expenses is as under.
A. Manpower expenses
8.2.17 The Authority notes that NMIAL has projected an average salary cost per employee of ₹ 16 lakh for
FY 2025-26 and has thereafter applied an annual escalation of 10% on Y-o-Y basis during the First
Control Period across all employee grades. Based on benchmarking with comparable airports, including
MIAL (Tariff order for the Fourth Control Period) and MoPA, Goa (Tariff order for First Control Period)
and guided by ICAO’s principles of ‘cost-relatedness’ which stipulates that aeronautical charges should
be derived from costs that are directly attributable, necessary, and efficiently incurred for the provision
of aeronautical services, the Authority considers the proposed average salary cost per employee of ₹ 16
lakh for FY 2025-26 to be reasonable. However, for the subsequent years of the First Control Period,
the Authority proposes to rationalize the escalation by applying a uniform annual growth rate to 6% Y-
o-Y basis, commencing from FY 2026-27, in line with the standardized approach adopted in recent
tariff orders. This calibrated approach ensures cost prudence, compliance with the principle of cost-
relatedness, and recovery of only efficient and justifiable manpower costs.
Allocation of manpower expenses
8.2.18 The Authority, taking into the account the above factor and EHCR as presented in Table 121, proposes
the following aeronautical manpower expenses for determination of tariff of the First Control Period of
NMIA.

B. Utility expenses
8.2.19 The Authority notes that NMIAL has estimated utility cost of ₹ 1,050.04 crore for the First Control
Period comprising of power, water and fuel cost at net level, i.e. gross expenses less recovery from
various users/concessionaires. The said expense also includes incremental expenses on account of
phase III operationalization during FY 2029-30.
8.2.20 The Authority has undertaken a detailed examination of the utility expenses which is presented below
Power Charges/Expenses
8.2.21 The Authority notes that NMIAL has projected annual electricity consumption and per unit cost as
given in para 8.1.9 based on its expectation of operating at 33 KV power distribution and transmission
in the initial years and thereafter moving to 220 KV connectivity considering the load requirements.
8.2.22 Considering that NMIA has commenced commercial operations from December 25, 2025, it is
understood that the power consumption will increase post COD. A broad level benchmarking exercise
was undertaken to estimate the per passenger power consumption proposed by NMIAL versus those
considered in tariff orders of CSMIA and IGIA.

8.2.23 The Authority notes that the average power consumption per passenger for the 5-year control period is
~3.17 units for CSMIA and ~3.35 units for IGIA. The average power consumption per passenger based
on NMIAL submission is ~5.72 units, which is considerably higher than CSMIA and IGIA. The
Consultation Paper No. 08/2025-26 Page 140 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
Authority is of the view that NMIA, being a greenfield airport, should install energy-efficient fixtures
and minimize overall power consumption. Accordingly, the Authority has proposed to consider power
consumption as 5 units per passenger for the first year and 4 units per passenger in the subsequent years
of the First Control Period.
8.2.24 The Authority notes that as per NMIAL’s submission, about 15% of gross power consumption will be
on recovery basis during the first year of operation, which would increase to 18% during the second
year and to 20% by the third year of First Control Period. The Independent Consultant undertook
benchmarking of recovery of electricity charges at CSMIA, IGIA and BIAL. The same is mentioned
below:

8.2.25 From the above table, it is noted that the electricity recovery considered is about 33% in the case of
CSMIA, 72% in the case IGIA and 50% in case of BIAL as per their latest tariff orders. The 15% to
20% recovery projected by NMIAL during the First Control Period is comparatively low. The Authority
is of the view that the recovery at NMIA will be more, and hence Authority proposes to consider
recovery of 33% of total power consumption. This recovery percentage from Concessionaires will be
trued up during tariff determination of Second Control Period. For this purpose, NMIAL is advised to
maintain proper record for the same which will be examined by the Authority at the time of true up.
8.2.26 Based on the supporting documents submitted by NMIAL, the Authority notes that NMIA draws
electricity from the local discom MAHAVITRAN under HT-II commercial category. As per the bills
provided by NMIAL, the procurement cost is around ₹ 19 per unit of electricity. As submitted in the
MYTP, the Authority proposes to consider ₹ 19 per unit as the procurement cost during FY 2025-26.
Thereafter, Y-o-Y increase in the rate of inflation as mentioned in Chapter 7 will be considered for unit
power cost.
8.2.27 The Authority notes that NMIAL in its MYTP submission had computed generation of ₹ 1.25 crore
units of power from solar energy. In response to the Independent Consultant’s query for the basis for
computation of power from solar energy, NMIAL submitted that the projection was based on
assumption that 10 MW of solar power will be installed in phase I. However, as per NMIAL’s revised
plan, 2.93 MW capacity will be operationalised in phase I and II by March 2026. Thus, it is projected
Consultation Paper No. 08/2025-26 Page 141 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
that about ₹ 0.37 crore units of power will be generated from solar power starting from FY 2026-27.
The revised units have been considered in power unit consumption from FY 2026-27 onwards.
8.2.28 Considering all the factors discussed above, the Authority proposes the power cost for the First Control
Period as follows:

Water Charges/Expenses
8.2.29 The Authority notes that NMIAL has projected annual water consumption and per unit cost as given in
para 8.1.9. The Independent Consultant appointed by the Authority had asked NMIAL for basis of their
projected water consumption. In their reply to the query, NMIAL submitted the details below:
Table 128: Water consumption submitted by NMIAL
Potable water consumption FY 2026
West
Terminal building + Airside 1624 KL per day
Landside 2091 KL per day

80% usage of potable water 3712.80 per day
Annual potable water consumption 13,55,172 KL
Potable water per pax 0.12 KL
8.2.30 Considering that NMIA has commenced its commercial operations, it is understood that the water
consumption may increase post COD. A broad level benchmarking exercise was undertaken to estimate
the per passenger water consumption proposed by NMIAL versus those considered in tariff orders of
CSMIA and IGIA.

Water consumption / pax (KL) 0.12 0.07 0.07 0.07 0.05
8.2.31 The Authority notes that the average water consumption per passenger for the 5-year control period is
about 0.04 KL for CSMIA and about 0.03 KL for IGIA. The average water consumption per passenger
as per NMIAL submission is about 0.07 KL, which is considerably higher than benchmark airports.
The Authority is of the view that being a greenfield airport, NMIA should deploy water-efficient
fixtures and leverage rainwater harvesting. Therefore, the Authority proposes considering 0.04 KL
water consumption per passenger for NMIA.
8.2.32 Further, the Authority notes that NMIAL has considered 10% recovery of water charges from the sub-
concessionaire. The Independent Consultant undertook benchmarking of recovery of water charges at
CSMIA and IGIA. The same is mentioned below:
Table 130: Benchmarking of recovery of water charges from sub-concessionaires across various airports

8.2.33 From the above it is noted that the average water recovery considered is about 26% in the case of
CSMIA and 95% in the case IGIA as per their latest tariff orders. The 10% water charges recovery
projected during the First Control Period for NMIA is comparatively low. The Authority is of the view
that MIAL being the operator of CSMIA and majority shareholder in NMIAL, it should make efforts
to adopt successful practices from CSMIA and maximize recoveries at NMIA. Thus, taking note of the
recovery percent at CSMIA, the Authority proposes to consider the recovery percent for NMIA as 25%
of total water consumption.
8.2.34 The Authority notes that as per the water bill dated February 16, 2024, submitted by NMIAL, water
charge is ₹ 52 per KL. Considering the inflationary increase of 2% over charge in year 2024, the
Authority proposes to consider the water charge of ₹ 53.04 per KL for FY 2025-26. Thereafter,
inflationary increase has been proposed.

Water Resource Development Charges
8.2.35 The Authority notes that NMIAL submission pertaining to Clause 10.10.3 of the Concession Agreement
pertaining to water resource development charges and that the amount payable to CIDCO in FY2028-
29 is still under discussion.
8.2.36 Accordingly, the Authority proposes to consider these water development charges on incurrence basis
subject to its reasonableness and prudence check during the true up exercise in Second Control Period.
Fuel / Diesel charges
8.2.37 The Authority notes that NMIAL has made provisions for diesel generator sets for power backup.
NMIAL submitted ₹ 2 crore towards the same for first year of operation.
8.2.38 The Independent Consultant appointed by the Authority had asked NMIAL for basis of their projected
fuel consumption. In their reply to the query, NMIAL submitted the details below:
Table 132 Basis of fuel cost submitted by NMIAL
Unit Oty. Rate Total (in ₹ crore)
DG diesel Diesel Liter 1,66,203 100 1.66
MT fuel Diesel Liter 79,152 100 0.79
Total of DG diesel & MT fuel (Diesel) 2.45
MT fuel Petrol Liter. 2,640 110 0.03
Total of DG diesel & MT fuel (Diesel & Petrol) 2.48
Since the basis for fuel cost submitted by NMIAL seems reasonable and the Airport operations have
started from December 25, 2025, the Authority proposes to consider the proportionate amount for
FY2025-26 and thereafter adjusted amount w.e.f. FY2026-27 onwards.
8.2.39 Taking the above factors into consideration, the Authority proposes the following utility expenses for
the First Control Period:

Consultation Paper No. 08/2025-26 Page 144 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
C. IT expenses
8.2.40 Authority notes that NMIAL has projected IT expenses as given in para 8.1.14. Authority also notes
that NMIAL has submitted one time increase of 4.40% during the 2nd year of operation. Thereafter the
annual increase in cost is considered as per the rate of inflation mentioned in para 8.1.13
8.2.41 The Authority through its Independent Consultant had asked NMIAL for the detailed breakup of IT
expenses.
8.2.42 NMIAL had submitted that discussions for various IT contracts were ongoing, and the same would be
made available to the Authority upon execution of contract. However, the particulars of expenses
estimated by NMIAL are as below:
Table 134: IT expenses per annum breakup submitted by NMIAL
(in ₹ crore)
Particulars Cost Remarks

10
twins, digital permit, video analytics, Digi Yatra, etc.
Total 40
8.2.43 The Authority notes that IT infrastructure pertains to the operations of the entire Airport. Further, the
Authority proposes to allocate IT expenses between aeronautical and non-aeronautical segregation
based on the GBR. NMIAL in its submission has considered a 10% Y-o-Y increase in IT expenses,
however, as per the Authority’s standard practice, a 6% Y-o-Y increase is proposed.

D. Rates and taxes
8.2.44 The Authority notes that NMIAL has made submission as per para 8.1.15 along with mentioning Clause
10.10 of the Concession Agreement pertaining to property tax/ service charges. As per NMIAL the
property tax/service charges are not ascertainable, hence has not included in rates and taxes in MYPT
submission and has requested to consider these on an incurrence basis. The Authority proposes to
consider the same on incurrence basis subject to reasonability and efficiency.
E. Corporate allocation
8.2.45 The Authority notes that NMIAL has submitted corporate allocation of ₹ 80 crore towards corporate
support services received from AEL and AAHL. Thereafter 10% Y-o-Y increase has been considered.
Consultation Paper No. 08/2025-26 Page 145 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
The Authority notes that NMIAL has not segregated expenses towards corporate allocation for the First
Control Period into aeronautical and non-aeronautical.
8.2.46 The Authority through the Independent Consultant had sought the basis for department wise expense
allocation. NMIAL has submitted the detailed breakup of this expense based on the study conducted by
PwC as provided in the table below.
Table 136: Corporate allocation cost basis submitted by NMIAL for FY 2025-26

8.2.47 The Authority notes that AEL, on an overall basis, extends support and guidance to various Group
Companies and AAHL provides expertise and specialist domain knowledge to the airport companies,
which are essential for the sustainable operations of the business. The major composition of the costs
of these services includes salaries and administrative costs that are recovered by AEL and AAHL
through an appropriate allocation method. Further, this process is consistent with the approach followed
by other PPP airports such as DIAL, GHIAL etc. for allocation of corporate costs to the airports. Based
on the above factors, the Authority considers the apportionment of costs of AEL and AAHL to NMIAL
as reasonable.
8.2.48 However, the Authority, on review of the above, observes that the corporate costs include cost towards
the in-house legal team. It is noted that the Authority has already allowed the employee expenses
towards the in-house legal team of NMIAL and therefore, it is of the view that providing additional
expenses towards the legal department at the corporate level would result in redundancy. Hence, the
Authority has excluded the same from aeronautical O&M expenses.
Consultation Paper No. 08/2025-26 Page 146 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
Based on the above, the Authority proposes not to consider the amount of ₹ 1.77 crore for AAHL and
₹ 0.30 crore for AEL towards such in-house legal team and allow the remaining amount of ₹ 77.13
towards corporate costs for FY 2025-26 after applying EHCR. The Authority advises NMIAL to submit
the actual corporate allocation numbers based on the financial statement of AEL & AAHL for the FY
2025-26, during the stakeholder consultation process to enable the Authority to take a further view on
the matter.
8.2.49 The Authority is also of the view that in the absence of an appropriate basis, corporate allocation cost
can be segregated in the employee ratio as mentioned in Table 122.
8.2.50 Additionally, the Authority proposes considering Y-o-Y growth of 6% for corporate allocation cost in
line with consideration in other Consultation Papers.
8.2.51 Based on the above analysis, the following table provides the corporate expenses of NMIAL as
proposed by the Authority for First Control Period.

F. Collection charges on UDF
8.2.52 The Authority notes that NMIAL has computed collection charges on only embarking/departing
passengers, excluding exempt and transfer passengers of 14% for domestic and 15% for international
passengers. However, the Authority proposes computing Collection Charges on disembarking
passengers, excluding exempt and transfer passengers of 7%.
8.2.53 The Authority further notes that NMIAL has considered Collection charges on UDF at ₹ 5 per departing
passenger. The Authority finds this rate consistent with approved rates in the recent orders for other
airports and therefore proposes considering the same rate for disembarking passengers to determine the
collection charges for the First Control Period.
8.2.54 The Collection Charges proposed by the Authority for the disembarking passenger, based on the revised
traffic as per Table for the First Control Period, as presented in the table below.

8.2.55 The Authority notes that NMIAL has submitted administrative and general expenses of ₹ 30 crore for
the FY 2025-26 as mentioned in para 8.1.24. Thereafter, Y-o-Y increase has been considered as per
Table.
8.2.56 The Authority through its Independent Consultant had sought details of expenses considered under the
administrative and general expenses head. NMIAL had submitted that these include legal expenses,
consultancy expenses, marketing and passenger engagement expenses, printing of baggage and cuss
rolls, etc.
8.2.57 In response to the query on the legal expense included under the administrative expenses, NMIAL had
submitted that the legal expenses are lump sum amount for various legal services which are required in
normal course of business, like retainer fees to law firms for preparing and filing pleadings in various
legal matters related to various land matters, disputes with airport stakeholders, etc.; compliances,
licensing, approvals and documentation costs; fees to legal counsels for appearing in court; etc. NMIAL
submitted the breakup of administrative expenses as detailed below:
Table 139: Breakup of administrative expenses submitted by NMIAL
(₹ in crore)
Administrative Expenses FY2025-26
Legal 6.00
Professional consultancy 6.00
Marketing and passenger engagement expenses 3.00

Printing of baggage rolls (1500 BTP per day) 1.25
Other misc. admin expenses 12.00
Total administrative expenses - others 30.00
8.2.58 The Authority notes that NMIAL has considered ₹ 6 crore towards marketing and passenger
engagement expense, printing expense. The Authority proposes considering the same.
8.2.59 The Authority notes that legal consultancy expense of ₹ 6 crore has been considered during FY 2025-
26, along with Y-o-Y increase thereafter. The Authority also observes that legal expenses incurred are
not predominantly related to the Airport operations. Further, there are legal officers who are on rolls of
MIAL for handling operational matters, and their costs are being allowed under employee costs. The
Authority is of the view that the legal expenses can be considered on a case-to-case basis, if the Airport
operator can establish that the incurrence of legal costs has any positive impact on the seamless and
efficient operations of the Airport. The Authority also noted that legal costs are not to be included as a
part of the pass-through costs of Airport operations. Therefore, the Authority proposes to exclude the
legal expense component at this stage while computing the administrative expenses for the First Control
Period.
Consultation Paper No. 08/2025-26 Page 148 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
8.2.60 The Authority had asked NMIAL to share details of expenses considered under the other miscellaneous
admin. expenses which amount to ₹ 12 crore per year, which are 40% of total administrative expense
(₹ 30 crore). NMIAL has submitted that these expenses are on account of expenses related to printing
and stationary expenses; daily office expenses; staff travelling, training, accommodation and
conveyance expenses; communication expenses related to mobile phones and payment to telecom
service providers. Considering the push towards go-green and sustainability initiatives, along with the
efficiencies that private sector is expected to bring in general administration, the Authority proposes to
consider ₹ 8 crore on account of other miscellaneous admin. expenses.
8.2.61 The Authority notes that NMIAL has not allocated administrative expenses based on any ratios.
However, the Authority proposes to allocate these expenses based on GBR in line with other airports.
8.2.62 Further, the Authority proposes to consider inflationary increase, as mentioned in Table 96for
administrative and general expenses.
8.2.63 In accordance with the aforementioned analysis and considering the GBR as mentioned in Table 122,
the aeronautical administrative expenses proposed by the Authority for the First Control Period are in
line with other airports and are as follows.

8.2.64 The Authority notes that NMIAL has considered the insurance cost at 0.10% of the initial asset base in
its MYTP submission, with a Y-o-Y increase of 10%. Additionally, the insurance expense for new assets
to be added during the control period have also been considered at 0.10% of the new additions to the
gross block based on market rates.
8.2.65 Authority notes that NMIAL has considered insurance for every aspect of infrastructure and operation
that is essential to ensure proper functioning of the airport.
8.2.66 NMIAL has submitted the policy document on February 16, 2026, whereby the insurance premium is
₹ 6.70 crore for the period from December 25, 2025, to October 18, 2026 (i.e. a total of 10 months),
which is significantly lower than the project amount for FY2026. This insurance corresponds to asset
value of ₹ 12,300 crore but does not cover the entire asset value ₹ 22,531 crore.
8.2.67 The Authority notes the insurance cost proposed for other greenfield airports such as MOPA, Goa and
NIA, Jewar is 0.09% and 0.05% respectively. Accordingly, the Authority has reviewed the same and
proposes to consider the average insurance expense of 0.07% on the revised gross block of assets along
with the inflationary increase of 3% Y-o-Y from FY 2026-27.
8.2.68 The total insurance cost proposed by the Authority for the First Control Period is as presented in the
table below:

I. Repairs and Maintenance
8.2.69 The Authority notes that NMIAL has estimated R&M cost of ₹ 937.87 crore for the First Control Period.
The Authority’s examination of R&M Cost is as below:
8.2.70 It is understood that NMIA, being a greenfield airport, will initially incur significant CAPEX costs but
require minimal R&M during the First Control Period. Therefore, the Authority is of the view that
NMIAL’s projected R&M expense as 1.10% to 1.20% of the opening gross block of assets (excluding
land development cost) over the First Control Period is reasonable. The Authority has compared the
average R&M expense as percentage of gross block (average of individual tariff years’ R&M as a
percentage of gross block) for the First Control Period of NMIA against that approved in the tariff
orders of other airports, specifically Bengaluru, Hyderabad and Mopa (Goa). In percentage terms, the
cost estimated is comparable to R&M allowed at MoPA Goa. The R&M expenses at MoPA Goa are
given below.

J. Other operating expenses
8.2.71 The Authority notes that the other operating expenses include expenses such as (i) housekeeping and
upkeep expenses; (ii) horticulture expenses; (iii) private security expense; and (iv) outsourced
manpower/ hire charges, which is ₹ 110 crore during FY 2025-26. Thereafter NMIAL has considered
Y-o-Y increase of 10%.
Consultation Paper No. 08/2025-26 Page 150 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
8.2.72 The Authority has taken note of the contract awarded by NMIAL for other operating expenses, which
was submitted on December 25, 2025. The contract has been awarded for a period of 7.5 months at a
contract price of ₹ 48.30 crore, translating to a monthly rate of ₹ 6.44 crore. The Authority proposes
considering the monthly rate of ₹ 6.44 crore to calculate the annual cost of the contract which comes to
be ₹ 77.28 crore.
8.2.73 The Authority has reviewed the contract in question, which comprises multiple activities that are a mix
of aeronautical, non-aeronautical, and common in nature. Due to the complexity of the contract and the
difficulty in segregating the costs associated with each activity, the Authority proposes adopting a
simplified approach to allocate costs. The Authority proposes applying an aeronautical allocation of
90% to the initial annual cost arrived as above i.e. ₹ 77.28 crore. So aeronautical portion comes to be ₹
69.55 crore for FY2025-26.
8.2.74 Based on the above, the total other operating cost proposed by the Authority for the First Control Period
is as presented in the table below.

K. CNS/ATM expenditure
8.2.75 The Authority notes that NMIAL has included expenses related to CNS/ATM services as part of the
O&M expenses for the First Control Period. In this regard, the Authority observes that these CNS/ATM
expenses pertain to the deficit between the TNLC charges collected by AAI during the previous year
and the actual cost of providing the service during the year, in accordance with clause 7.4 of the
CNS/ATM agreement, which is mentioned below:
“The provision of CNS-ATM services as mentioned in Clause 5.1 shall be on cost recovery basis.
Further, TNLC revenues collected by AAI shall be deducted from the actual cost of providing the
CNS/ATM services during that year (cost includes prorated capital cost and all the operating costs
including staff cost). …
Deficit, if any, between the actual cost of providing the CNS/ATM services during that year (cost
includes pro-rated capital cost and all the operating costs including staff cost) and TNLC revenues in
the first 3 years will be recovered with 12% interest from 4th, 5th and 6th years. If any uncovered deficit
at the end of 6th year, the same will be paid by Airport Company to AAI. …”
8.2.76 Additionally, the expenditure includes depreciation of ₹ 14.67 crore p.a. related to the CAPEX of ₹ 220
crore incurred by AAI for the development of CNS/ATM facilities required for phases I & II of the
Consultation Paper No. 08/2025-26 Page 151 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
project. The expenditure also includes annual operating expense for providing TNLC services of ₹ 70
crore towards CNS with 10% annual escalation and ₹ 60.60 crore towards ATM post COD both with
10% annual escalation.
8.2.77 Now, AAI has clarified vide mail dated March 11, 2026, that the CNS/ATM operating expense
(manpower cost and other operating expenses) include an overhead component of 30%. This overhead
component does not have a clear and demonstrable linkage to incremental administrative or support
services over and above those already embedded within these CNS/ATM expenses attributable
specifically to the airport. Given that CNS/ATM services are provided by AAI uniformly across all the
airports as a Centralized statutory function, the associated administrative and support costs are expected
to be absorbed within AAI’s overall cost structure and reflected in the base operating costs. In the
absence of a transparent, airport-specific cost allocation methodology, loading an additional overhead
on an ad-hoc percentage basis would result in double counting of costs and an unjustified pass-through
to passengers. Accordingly, the Authority proposes not to consider the overhead component. However,
the Authority invites comments from stakeholders on this issue of 30% overhead costs applied by AAI,
that will ultimately be borne by passengers. The Authority will take a final view on this matter during
the stakeholder consultation based on the comments received from stakeholders. The Authority also
notes that as airport traffic and operational volumes stabilize and improve, AAI would be in a position
to progressively absorb and offset any projected overheads since in the subsequent years all excess
revenue collected by AAI from TNLC over and above their operating costs would be retained by AAI
only.
8.2.78 The Authority has examined the break-up of CAPEX submitted by NMIAL and notes that it pertains to
the cost incurred by AAI for development of CNS/ATM facilities. Accordingly, the Authority proposes
to consider the capital cost of ₹ 220 crore to be amortized over 15 years from COD as submitted by
NMIAL.
8.2.79 AAI was requested to submit the revised CNS/ATM expenditure from FY2027 onwards. However, AAI
has not provided the same. Accordingly the Authority proposes to consider the operating expense of ₹
130.60 crore as CNS/ATM expenditure for FY 2025-26. For the remaining years of the control period,
the Authority proposes Y-o-Y inflationary increase of 3% as per Table 96 for CNS/ATM expenses.
8.2.80 The Authority also proposes to consider TNLC in accordance with the tariff specified in the DGCA
AIC dated September 30, 2020, considering the arrival and departure ATMs in a 50:50 ratio.
8.2.81 The revised CNS/ATM Expenditure proposed by the Authority considering the revised ATMs as
computed by the Authority for the First Control Period is given below:

8.2.82 The CNS/ATM Expenditure as determined above is considered as 100% aeronautical in line with
Clause 2.2.4 of the MoU between NMIAL and GoI which states that “Any payments made by the
Concessionaire to or on behalf of any Government Instrumentality for providing Reserved Services
except Security Services, within the Airport shall be considered as pass through for the purpose of the
determination of the Aeronautical Charges.”
L. Concession fee (fixed)
8.2.83 The Authority notes that as per clause 26.1.3 and 26.1.4 of the Concession Agreement:
“The Concession Fees shall be payable in advance within 7 (seven) days of the commencement of each
Concession Year during the Concession Period”
“The Concession Fees shall be considered as a part of the operating expense for the purpose of the
determination of the Aeronautical Charges”
Concession fee is payable with effect from the Appointed Date (July 7, 2018). As mentioned in para
8.1.37, the Concession fee payable is ₹ 5 crore from Concession Year 1 to Concession Year 9 and ₹ 10
crore from Concession Year 10 to Concession Year 15. Accordingly, FY 2025-26 to FY 2029-30 of the
or the First Control Period correspond to 8th to 12th Concession Year of the Concession Period.
Further, the Authority notes that Concession Fee is required to be paid by the NMIAL to CIDCO
(Concessioning Authority) in advance within seven days from the commencement of each Concession
Year during the Concession Period, i.e., prior to the start of July month of the respective year. The
Authority also notes that Concession Fee totalling ₹40 crore has been paid prior to the start of
commercial operations on December 25, 2025, of NMIA and in line with the applicable regulatory
treatment, such expenditure is proposed to be capitalized.
Consultation Paper No. 08/2025-26 Page 153 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
Considering that the concession fee payment in July 2025 i.e. the 8th Concession Year, the
corresponding expense for FY 2025-26 is proposed to be considered as Nil. For subsequent years of
the First Control Period the concession fee would be considered correspond to 9th to 12th Concession
Year of the Concession Period. Accordingly, the Authority proposes to consider concession fee as below
during the First Control Period.

M. Independent Engineer cost
8.2.84 NMIAL has submitted an amount of ₹ 30.53 crore as being incurred to acquire services of an
independent engineer as part of OPEX for the First Control Period. The Authority reviewed Article 23
of the Concession Agreement, which details the requirement for Independent Engineer as below:
“The Authority shall appoint a consulting engineering firm substantially in accordance with the
selection criteria set forth in Schedule-M, to be the Independent Consultant under this agreement
(“Independent Engineer”). The appointment of the Independent Engineer shall be made within 30
(thirty days) of the date of execution of this Agreement and such appointment shall be valid until Phase
I COD. On or prior to the expiry or termination of the said appointment, the Authority shall appoint an
Independent Engineer for a further term of 3 (three) years in accordance with the provisions of
Schedule-M, and such procedure shall be repeated after expiry of each appointment”.
8.2.85 According to Clause 2.1 of Schedule M to the CA,
“In determining the nature and quantum of duties and services to be performed by the Independent
Engineer during the Development Period, Construction Period and Operation period, the Authority
shall endeavour that payments to the Independent Engineer on account of fee and expenses shall be
determined on the basis of the competitive bidding process.”
According to Clause 2.2 of Schedule M to the CA,
“The remuneration, cost and expenses of the Independent Engineer shall be paid by the Authority, and
all such remuneration, cost and expense shall be reimbursed by the Concessionaire to the Authority
within 15 (fifteen) days of receiving a statement of expenditure from the Authority.”
According to Clause 2.3 of Schedule M to the CA,
“Any amount paid to the Independent Engineer shall be pass-through for the determination of the
Aeronautical charges by AERA.”
8.2.86 The Authority has reviewed the LoA dated January 31, 2023, issued for the extension of services,
following the expiry of the contract agreement dated October 28, 2022. The LoA provides an extension
of 26 months, up to December 30, 2024, at a total cost of ₹ 19.99 crore plus GST. On an annual basis,
the cost comes out to be ₹ 9.23 crore.
8.2.87 It is noted that NMIAL has estimated only around 50% of such expenses post COD, i.e., ₹ 5 crore as
part of their MYTP submission. As per the above discussions, the Authority proposes considering the
Consultation Paper No. 08/2025-26 Page 154 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
cost of ₹ 5 crore submitted by NMIAL for the Independent Engineer to be reasonable and justified.
However, yearly increase has been considered as per Table 154.

N. Digitisation cost
8.2.88 The Authority notes that NMIAL has estimated the digitisation cost of ₹ 672 crore for the First Control
Period towards digital transformation / technology intervention where an airport operator can provide
end to end services to the consumers (origin to destination) on single platform which will result in
enhanced consumer experience and more satisfaction. NMIAL has considered digitisation cost of ₹ 110
crore in the first year with an annual escalation of 10%.
8.2.89 NMIAL vide email dated January 22, 2026, submitted that it has onboarded a related party i.e. Adani
Digital Labs Private Limited for the digital platform contract and shared the details of the LoA dated
December 9, 2025, for annual lump sum amount of ₹ 100 crore.
8.2.90 NMIAL has submitted that in accordance with the RPT requirements under the Concession Agreement
on becoming aware of likely participation by Adani Digital Labs Private Limited and it being a related
party, M/s CNK & Associates LLP (Chartered Accountants) were appointed as Independent Probity
Auditors (IPA) vide letter dated August 9, 2024, for overseeing the process followed for the tendering
process.
8.2.91 NMIAL has submitted that it has undertaken two stage bidding process for selection of the partner for
Digital Platform Services.
“3.3.1 Technical Eligibility Criteria:

3.3.2 Financial Eligibility Criteria:
As of the previous financial year from the date of submission of Application the Applicant must have:
(i) an annual turnover of at least Rs. 25 crores.
AND
(ii) positive net worth.”
8.2.92 At the RFQ stage, the following bidders participated
Consultation Paper No. 08/2025-26 Page 155 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
• M/s Adani Digital Labs Private Limited
• M/s Advaiya Solutions Private Limited
• M/s Binmile Technologies Private Limited
• M/s IBM India Private Limited
• M/s Kellton Tech Solutions Limited
• M/s Graymatter Software Services Private Limited
IPA in its report dated August 11, 2025 has submitted that based on evaluation of bids at RFQ stage,
the bidder M/s IBM India Private Limited had requested to allow submission of BG in lieu of RFQ fees
after receipt of RFQ document, NMIAL agreed to waive the same in interest of encouraging
competition in the RFP stage. M/s Binmile Technologies Private Limited did not meet the technical
eligibility criteria stipulated in clause 3.3.1 (ii) of the RFQ and hence disqualified for the RFP stage and
M/s Kellton Tech Solutions Limited failed to provide the power of attorney, despite multiple requests.
8.2.93 Further, IPA in its report dated August 11, 2025 has submitted that based on evaluation of bids, the RFP
for providing Digital Platform Services for the airport, was published on June 5, 2025 on the e-
procurement portal of NMIALto the following four qualified parties.
• M/s Adani Digital Labs Private Limited
• M/s Advaiya Solutions Private Limited
• M/s IBM India Private Limited
• M/s Graymatter Software Services Private Limited
8.2.94 Subsequently, only the following three bidders participated.
• M/s Adani Digital Labs Private Limited
• M/s Advaiya Solutions Private Limited
• M/s Graymatter Software Services Private Limited
However, the bid submitted by M/s Graymatter Software Services Private Limited was considered non-
responsive due to non-submission of financial proposal as per format specified and non-payment of bid
security. M/s Adani Digital Labs Private Limited quoted the lowest Services Fees for providing the
Digital Platform Services.
8.2.95 NMIAL has submitted that IPA has certified the selection of RPT at arm’s length and in ordinary course
of business in compliance of the Concession Agreement. Further, the NMIAL has submitted the Board
Resolution of the NMIAL board meeting held on December 5, 2025, stating that NMIAL board has
accorded approval for awarding the rights to render Digital Platform Services to the related party, Adani
Digital Labs Private Limited.
8.2.96 The Authority notes that the IPA’s report on tender process for airport services concludes the following:
“We refer to our engagement letter dated August 9, 2024. The scope involves reviewing the process
followed by NMIAL for shortlisting/selection of the service provider and whether the same is as per the
requirements of Concession Agreement and the process laid down in the tender document and verifying
that the tender is awarded to the lowest bidder. Since one of the bidders is a related party of NMIAL,
the scope included verification of the compliance with the terms of Concession Agreement entered with
Consultation Paper No. 08/2025-26 Page 156 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
CIDCO related to related party transactions (RPT) and whether the successful bidder/applicant is
selected at arm’s length as stipulated in clause 5.6.3 of the Concession Agreement. This includes
verification of the process by which the applicants qualify to bid as per the qualification terms. This
would include an evaluation of the online process of bidding for the technical and financial eligibility
of applicants and a report on whether the same are as per the terms and conditions as laid down in the
tender document and considered as arm’s length in the context of the tender document being awarded
to the lowest bidder.”
8.2.97 The Authority has examined the awarded cost for digitisation services, which includes costs towards
onboarding and fixed costs to digital services. In its previous decision for MIAL, the Authority
recomputed the digitisation cost by treating onboarding costs and loyalty program costs as non-
aeronautical costs. Specifically, the Authority decided to consider 30% fixed cost to the digital service
provider as part of operating expenses.
8.2.98 Based on the approach adopted for MIAL, the Authority notes that onboarding costs accounted for
approximately 13.11% of the total digitisation cost, excluding loyalty programs. In the absence of
specific information on the onboarding costs for NMIAL, the Authority proposes to apply a similar
percentage to the total digitisation cost of ₹ 100 crore. Accordingly, ₹ 13.11 crore (13.11% of ₹ 100
crore) is estimated as onboarding cost and proposed to be treated as non-aeronautical. Further, Y-o-Y
increase of 5% has been considered in line with MIAL.
8.2.99 Further, based on Multi Criteria Decision Approach (MCDA) used in MIAL, the Authority proposes to
allocate digitisation expense at 30%. MCDA approach employs a list of variables to segregate the costs,
with each variable assigned a score between 1 to 5. The Aeronautical and Non-Aeronautical Services
are grouped into categories based on their functions, and each category is assigned a score under each
variable. This approach is used to allocate digitisation costs between Aeronautical and Non-
Aeronautical services, considering factors such as the utility of service coverage, nature of revenues
generated, and passenger feedback.
8.2.100 Based on above, the Authority proposes considering the digitisation cost as below:

O. Financing charges and others
8.2.101 The Authority notes that NMIAL has submitted financing charges of ₹ 332.36 crore, which includes
bank charges for routine operations, debt arranging charges, processing fees and upfront fees payable
Consultation Paper No. 08/2025-26 Page 157 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
to lenders, documentation charges, and various agencies. This includes the financing charges of ₹
321.94 crore calculated at 1.50% per annum on debt drawdown for First Control Period and
Performance Bank Guarantee (PBG) expense of ₹ 10.42 crore for the First Control Period.
8.2.102 The Authority proposes considering 1.50% financing charges on debt drawdown for minor CAPEX
during the First Control Period.
8.2.103 Authority further proposes to consider annual fee of 1% of the performance bank guarantee given to
CIDCO to be paid to SBI as per sanction letter.
8.2.104 Authority also proposes to allocate financing charges for arranging debt and PBG expenses based on
GBR.

P. Interest on Working Capital
8.2.106 The Authority notes that NMIAL has submitted interest on working capital loan of ₹ 378.36 crore.
8.2.107 Authority brings reference to para 5.4.3 of the AERA Guidelines for Tariff Determination, 2011, the
relevant extract of which is given below.
“……The Authority shall consider interest on short term loans, generally raised towards working
capital with a maturity of less than one year, as operation and maintenance expenditure to address the
working capital requirement. The Airport Operator shall submit to the Authority the proposed levels of
working capital requirements and shall demonstrate that the proposed working capital loans are not
excessive in relation to such levels of working capital. The Authority shall not consider any allowance
provided for allocations for bad debts in the working capital. The Authority shall review and assess the
levels of projected working capital requirements and shall consider cost of working capital loans as
deemed appropriate. However, such loans would not be considered in the calculation of the cost of
debt.…..”
Consultation Paper No. 08/2025-26 Page 158 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
8.2.108 The Authority observed that NMIAL has calculated the interest on the working capital loan based on
the projected recovery of revenue and payment of expenses, considering receivable days as 45 and
payable days as 15. Accordingly, NMIAL has submitted in its MYTP that there was a requirement for
working capital for all tariff years of the First Control Period. Authority also notes that the applicable
rate of interest is same as interest in loan facility by senior lender SBI.
8.2.109 The Authority proposes to consider the interest on working capital at the rate of 10.09% calculated at 6
months SBI MCLR of 8.60% + 1.55% basis points as per the SBI sanction letter submitted by NMIAL.
8.2.110 The Authority notes that interest on working capital is dependent on many factors including
aeronautical revenue which is in turn dependent on the tariff rate card. However, since the tariff rate
card would be submitted by the Airport Operator only after the issue of this consultation paper, the
Authority, for the purposes of this consultation paper, proposes to consider the interest on working
capital corresponding to each tariff year as submitted by NMIAL in their financial model.
8.2.111 The Authority further proposes to recompute the interest on working capital at the time of Tariff Order,
considering any changes to the building blocks and changes in Aeronautical Revenue based on the tariff
decided by the Authority.
8.2.112 The Total Interest on Working Capital proposed by the Authority for the First Control Period is as given

Consultation Paper No. 08/2025-26 Page 161 of 202OPERATION & MAINTENANCE EXPENSES FOR THE FIRST CONTROL PERIOD
8.2.126 The Authority notes that the IPA’s report on tender process for airport services concludes the following:
Based on our review of the process followed by NMIAL for the bidding process for appointment of the
Service Provider for Operations and Maintenance (“O&M”) services for cargo terminal(s) at the
airport, and based on our scope of work as mentioned above, and the information and explanations
provided to us, in our view, we report that NMIAL has followed the standard process and has conducted
the bidding process in a fair and transparent manner with respect to the Tender Document. We further
report that the online bidding process has been conducted as per the terms of the Concession Agreement
in respect of Related Party and the proposed award of contract to Adani Global Air Cargo Solutions
Limited is at arm’s length in accordance with clause 5.6.3 of the Concession Agreement, being the
lowest bidder.
8.2.127 NMIAL has submitted to the Authority a copy of the minutes of 3rd meeting of RPT Audit Committee
held on January 31, 2025, to discuss, consider and approve the contract of cargo terminal(s) O&M. The
Authority notes that basis the discussion, input and thereafter confirmation by the IPA that the
transaction was at arms’ length and in ordinary course of business, the RPT Audit Committee had
declared AGACSL as winner for the bid for O&M of cargo terminal(s) at NMIA. Additionally, a copy
of the shareholders resolution passed in the 18th Annual General Meeting on June 18, 2025, by members
of NMIAL, submitted to the Authority, also concludes the aforementioned.
8.2.128 Basis the review, the Authority understands that selection of AGACSL as preferred bidder for O&M of
cargo terminal(s) has been in ordinary course of business and at arm’s length. The Authority expects
that going forward, NMIAL and CIDCO (Concession granting agency) will ensure that the future
contracts with related parties are also at arms’ length and that the related party has relevant experience
of providing similar services to ensure protection of interest of all stakeholders, as per the terms of the
Concession Agreement detailed above, which may be followed in letter and spirit.
8.2.129 The Authority notes that the cargo complex being a 24*7 facility, to monitor the operations by O&M
agency, NMIAL has considered 1 supervisor and 1 duty manager per shift i.e. 3 shifts. The Authority
proposes considering the same.
8.2.130 It is noted that the average salary for supervisory/executive level employees range from ₹ 25 lakh to ₹
50 lakh per annum. NMIAL has submitted salary of ₹ 33 lakh, which the Authority proposes to consider.
However, NMIAL has projected salary increase at 10% Y-o-Y, which the Authority proposes to consider
at 6%, as being considered for NMIA employees in para 8.2.17.
8.2.131 During analysis it was observed that NMIAL had inadvertently miscalculated the average salary for
customs staff. NMIAL has considered the average salary per custom staff as ₹ 42 lakh per annum, which
actually comes to about ₹ 31 lakh per annum.
8.2.132 To analyse the reasonability of the cargo expenses (including O&M agency fee) projected by NMIAL,
the Authority undertook a benchmarking exercise. As per the tariff orders for respective cargo
Independent Service Providers (ISPs), the O&M cost approved per ton at IGIA and CSMIA for FY
2025-26 is as below:
Table 151: Cargo O&M benchmarking with other airports

NMIAL AGACSL O&M expense – excl concession fee (₹ crore) 272.84
O&M / Ton 10,293.94
8.2.133 The Authority notes that as per the tariff orders, for FY 2025-26 the O&M expense/ton for IGIA and
CSMIA is about ₹ 10,042 per ton. Considering NMIA’s scale and proximity to CSMIA, it may be
considered that the cargo expense at NMIA may be in range of CSMIA and IGIA. However, NMIAL
has projected O&M operator fee increase at 10% Y-o-Y, which the Authority proposes to consider at
the rate of inflation, as mentioned in para 8.2.15.
8.2.134 Additionally, for CISF manpower expense and other expense NMIAL has considered increase at 10%
Y-o-Y, which the Authority proposes to consider at the rate of inflation, as mentioned in para 8.2.15.
8.2.135 As per the MYTP submission, NMIAL, apart from the salary cost of their own employees, has projected
reimbursement of salary cost of customs officials who will be handling the international cargo
operations, under the head ‘Customs cost recovery’. The Authority notes that the airport operator has
estimated the salary cost of the customs officials as per Para 7 of the circular issued by the Department
of Revenue, Ministry of Finance vide Circular No. 02/2021-Customs dated January 19, 2021. Since the
international cargo operations are planned to be commenced in April 2026 therefore, custom cost
recovery for FY 2026 has been considered as nil. Accordingly, NMIAL will have to bear custom cost
recovery charges of ₹ 36.42 crore for FY2026-27 and ₹ 72.84 crore for FY2027-28 for sanctioned staff
of 116 and 232 respectively. In view of the projection proposed by the Authority as per Table 13, it is
expected that NMIAL will be able to demonstrate international cargo volumes much more than 12,000
MT threshold for air cargo complex for continuous two financial years i.e., FY2027 and FY2028.
Accordingly, NMIAL would be eligible for the custom cost waiver applicable in case of international
cargo volume from FY2028-29.
8.2.136 Further, Authority also notes that NMIAL in its submission has considered other expenses as part of
total cargo O&M expense. However, in the recent Tariff Orders released by Authority for Jaipur,
Guwahati and Trivandrum Airports, other expenses have not been proposed by the Airport Operator. In
line with the precedence, Authority proposes not to consider other expenses under cargo O&M
expenses.
8.2.137 The Authority proposes considering cargo O&M expenses as below:

Total non-aero revenue 30.00 53.20 66.66 73.33 124.29 347.49
9.2 Authority’s examination regarding NAR for the First Control Period
9.2.1 The Authority has examined the basis and the projections of non-aeronautical revenue submitted by
NMIAL for the First Control Period.
9.2.2 The Authority has noted the gross revenue share (10.05%) outcome of the tendering process for MSA
and is of the view that this revenue share is significantly low. Further, the Authority also opines that it
is the responsibility of NMIAL to ensure that the Airport achieves higher NAR during the First Control
Period. In this context, there was no obligation on NMIAL to accept the bid of Master concessionaire
offering such low revenue shares.
9.2.3 Further, the Authority notes that NMIAL has awarded master service agreement (MSA) contract for
non-aeronautical services to the master concessionaire which is a related party i.e., M/s Adani Airport
Holdings Limited (AAHL). In this context, the Authority takes note of Clauses 5.6.2 and 5.6.3 of the
Concession Agreement as detailed in para 2.5.10 pertaining to open competitive bidding requirement
and related party transactions.
9.2.4 Accordingly, the Authority, through its Independent Consultant had asked NMIAL for the details of the
bid process followed. NMIAL has submitted that following a two-stage global competitive bidding
process, the master concessionaire has been selected as Adani Airport Holdings Limited (AAHL). M/s
Ernst and Young LLP (“EY”) was engaged as an Independent Consultant to oversee the bid process,
Consultation Paper No. 08/2025-26 Page 173 of 202NON-AERONAUTICAL REVENUE FOR THE FIRST CONTROL PERIOD
while M/s Cyril Amarchand Mangaldas (CAM) was engaged as an independent legal advisor for the
same.
9.2.5 NMIAL has submitted that since AAHL is a related party, the independent probity auditor – CNK &
company (appointed by CIDCO on June 08, 2023) was onboarded to oversee the complete tender
process including drafting of RFP and eventual agreement.
9.2.6 Based on the documents shared it is noted that following an advertisement on June 5, 2023, the RFQ
for airport services was published on NMIA’s e-procurement portal on June 22,2023 for undertaking
Airport Services at Terminal 1 and landside development at NMIA.
9.2.7 At the RFQ stage, applications were received from the following applicants:
i) GMR Airports Limited
ii) DB Realty Limited
iii) Adani Airport Holdings Limited
9.2.8 Subsequently, NMIAL published a newspaper advertisement on November 25, 2023, informing about
the extension of last date of submission of application on account of amendment in the scope of
services.
9.2.9 Thereafter NMIAL also issued corrigendum-1 to RFQ dated December 6, 2023 with the
aforementioned applicants in para 9.2.7 to inform about amendments in scope of work and seek their
interest and declaration on continued eligibility in the bidding process. Summary of key changes in the
corrigendum-1 is provided below:

9.2.10 As per RFQ evaluation report dated December 11, 2023, there were no new applications received in
the extension period. The aforementioned applicants in para 9.2.7 had all submitted declarations for
continued eligibility and were declared qualified bidders for RFP stage.
9.2.11 Thereafter, the RFP was published on December 12, 2023, on NMIAL’s e-procurement portal and
shared with the qualified bidders from RFQ stage. The Authority notes that at the RFP stage, the
financial bid evaluation criteria were a combination of Minimum Annual Guarantee (MAG) and
revenue share percent.
Based on the evaluation at the RFP stage, none of the bidders at RFP stage quoted any MAG. The
related party, AAHL had quoted the highest revenue share percent and was hence selected as the master
concessionaire and the MSA was signed on September 21, 2024.
9.2.12 As per the IPA’s review report dated April 23, 2024, the tender process for airport services has
concluded the following:
“Based on our review of the process followed by NMIAL for the bidding process for appointment of the
Service Provider for Airport Services, and based on our scope of work as mentioned above, and the
information and explanations provided to us, in our view, we report that NMIAL has followed the
standard process and has conducted the bidding process in a fair and transparent manner with respect
to the Tender Document. We further report that the online bidding process has been conducted as per
the terms of the Concession Agreement in respect of Related Party and the proposed award of contract
to AAHL is at arm’s length in accordance with clause 5.6.3 of the Concession Agreement, being the
highest bidder.”
9.2.13 NMIAL has submitted that the proposed related party transaction (RPT) was formally intimated to
CIDCO and the required shareholder meeting (as per Concession Agreement), RPT Audit Committee
meeting (as per Companies Act, 2013) were also held. Thereafter, the NMIAL board in its meeting
dated July 2, 2024, considered the proposed RPT granted its approval on the same.
9.2.14 The Authority has noted the two-stage tendering process followed by NMIAL. However, in view of the
limited participation for the MSA services at RFQ stage, the Authority has examined the extract of the
relevant clauses of the RFQ which read as below:
“3.3.1 Technical Eligibility Criteria:
The Applicant shall have the experience as below:
Consultation Paper No. 08/2025-26 Page 175 of 202NON-AERONAUTICAL REVENUE FOR THE FIRST CONTROL PERIOD
i. At the time of submission of the Application, the Applicant shall be either– (A) an Entity having

i.e. (I) duty-free retail; (II) duty paid retail and services; (III) food and beverage services;
(IV) car parking; and (V) advertisement; AND
b. at least ten lakh (10,00,000) square feet (in aggregate) on the landside of an international
airport in India from any or a combination of any of the following, i.e. (I) hospitality, (II)
office spaces, (III) retail, (IV) entertainment and (V) convention centre.
OR

AND
b. at least 3 (three) out of the following 5 (five) facilities over minimum forty lakh (40,00,000)

residential and (V) convention centre; AND
c. at least one project from (b) above should be part of landside development of an international

3.3.2 Financial Eligibility Criteria:
As at 31st March 2023, the Applicant must have:
i. an annual turnover of at least Rs. 500 crores; AND
ii. Net Worth of Rs. 1500 crores.”
9.2.15 From the RFQ qualifying criteria specified above by NMIAL, the Authority has the following
observations:
Technical Eligibility Criteria
• NMIAL has specified in their technical eligibility criteria that bidder should either be an Entity who
has rights / experience in operations or management or development or be an Entity who is an
airport operator having the right to develop at least 3 (three) out of the following 5 (five) businesses
at an international airport in India, i.e. (I) duty-free retail; (II) duty paid retail and services; (III)
food and beverage services; (IV) car parking; and (V) advertisement;
The Authority notes that this criterion seeks that two (2) out of the five (5) businesses, namely duty-
free retail and duty paid retail, and services are specific to airports sector. As per GoI Guidelines
for PPP development, the criteria requiring airport experience even for leasing out the airport has
been dispensed with. Therefore, the Authority is of the view that asking for airport specific services
related experience for Master Service Agreement is restrictive.
Consultation Paper No. 08/2025-26 Page 176 of 202NON-AERONAUTICAL REVENUE FOR THE FIRST CONTROL PERIOD
• It is noted that NMIAL has specified that bidder be an Entity having rights / experience in
operations or management or development or be an airport operator having the right to develop the
businesses of at least ten lakh (10,00,000) square feet (in aggregate) on the landside of an
international airport in India from any or a combination of any of the following, i.e. (I) hospitality,
(II) office spaces, (III) retail, (IV) entertainment and (V) convention centre.
The Authority notes that the requirement for an Airport in India with terminal having area for non-
aeronautical or commercial activities of 2,31,354 sqm, of which 25,356 sqm. is considered for non-
aeronautical or commercial activities. This is about 10.95% of the terminal building. Considering
the present scope of work, specifying 10,00,000 sqm commercial space as eligibility criteria is too
high. Additionally, requiring experience only on landside of an international airport is additionally
restrictive.
Financial Eligibility Criteria
• Turnover
As per Public Procurement Guidelines, the average financial turnover should be 30% of the
estimate cost. Considering the projected cumulative NAR of Rs. 347 crore submitted by NMIAL
for the First Control Period, in place of requirement of Rs 105 crores (30% *347) average annual
turnover, NMIAL has specified a turnover of Rs. 500 crore (which is more than 4 times).
• Net Worth
The net worth of Rs 1,500 crore is additionally restrictive for a work value of Rs. 350 crore, as
several Airport Operators like AAI etc. are specifying only Positive Net Worth.
The Authority is of the view that due to such restrictive criteria, only 3 agencies (including 1 related
party) participated in the tender. The Authority expects that going forward, NMIAL and CIDCO
(Concession granting Agency) will ensure that the tenders for providing similar services are scrutinized
for any restrictive eligibility criteria. This is not only to attract more agencies and encourage healthy
competition but also to ensure protection of interest of all stakeholders, as per the terms of the
Concession Agreement detailed above, which may be followed in letter and spirit.
9.2.16 The Authority notes that airports developed under PPP framework, including NMIA are envisaged to
deliver operational and commercial operational efficiencies through professional airport management.
A key objective of the PPP framework is to enable the enhancement of non-aeronautical revenues by
the airport operators, thereby facilitating cross-subsidisation of aeronautical charges. Such cross-
subsidisation allows efficiency gains and commercial upside to be shared with airport users in the form
of moderated aeronautical tariffs, while safeguarding passenger interests and ensuring the financial
viability and sustainability of airport operations.
9.2.17 In order to assess the reasonableness of the NAR projections submitted by NMIAL, the Authority has
undertaken a benchmarking exercise with comparable PPP airports, this includes not only CSMIA
Mumbai but also other greenfield airports such as Manohar International Airport (MOPA), Goa. These
airports provide relevant reference points, given their greenfield nature, comparable concession
structures, and reliance on non-aeronautical revenues as an important instrument for moderating
aeronautical tariffs. The outcome of the benchmarking exercise is summarized in table below:

*For CSMIA, NAR revenue excludes ground handling revenue, rent & services revenue and cargo revenue
9.2.18 Based on the benchmarking exercise discussed above, the Authority observes that the non-aeronautical
revenue projections submitted by NMIAL are materially lower than the levels projected and/or achieved
at other greenfield airports such as MOPA. This is notwithstanding the fact that non-aeronautical
revenue per passenger at these airports envisaged during the initial years of operations is substantially
higher than those projected by NMIAL. The Authority further notes that even for airports located in
tier-2 cities, non-aeronautical revenues have demonstrated meaningful commercial potential. This
indicates that the assumptions adopted by NMIAL are conservative and do not fully reflect prevailing
industry experience or demonstrated commercial outcomes.
9.2.19 The Authority is of the view that such subdued non-aeronautical revenue projections are not aligned
with the interest of passengers and other stakeholders. Lower NAR projections directly increase
reliance on aeronautical charges for revenue recovery, thereby exerting upward pressure on tariff
payable by passengers. At the same time, Airport Operator continues to recover full costs through return
on RAB, OPEX, depreciation and applicable taxes. Consequently, the commercial risk associated with
under-performance of non-aeronautical revenues is effectively transferred to passengers, which is
inconsistent with the principles and intent of the PPP framework.
9.2.20 The Authority further notes that NMIA being located within the MMR and catering to a passenger
profile comparable to CSMIA, possess substantial inherent potential for generation of non-aeronautical
revenues. Passenger spending on retail, food, beverages, car parking and other commercial services is
expected to be robust, notwithstanding the greenfield status of the Airport. While the Authority
recognizes that a reasonable ramp-up period may be required for stabilisation of such revenues in the
initial years of operations, this does not justify the significantly lower non-aeronautical revenue
assumptions proposed by NMIAL, particularly when benchmarked against comparable greenfield
airport.
9.2.21 In view of the foregoing, the Authority has adopted a benchmarking-based and efficiency-oriented
approach for determining non-aeronautical revenue projections for NMIA. This approach reflects
realistic commercial potential, incorporates a phased ramp-up consistent with the greenfield nature of
the Airport and ensures optimal cross-subsidisation of aeronautical revenues. The Authority is of the
view that such an approach is necessary to moderate aeronautical tariffs and maintain airport charges
at reasonable and affordable levels, while simultaneously ensuring that the airport operator continues
to receive full and fair cost recovery, including return on RAB, OPEX, depreciation, and taxes.

Consultation Paper No. 08/2025-26 Page 179 of 202TAXATION FOR THE FIRST CONTROL PERIOD
10. TAXATION FOR THE FIRST CONTROL PERIOD
10.1 NMIAL’s submission regarding aeronautical taxation for the First Control Period
10.1.1 NMIAL has submitted that it has considered an effective tax rate of 25.17%. The computation of
aeronautical income tax has been made based on regulatory books. Further, the aeronautical segment
has been treated as a standalone entity with its own tax computations.
10.1.2 While calculating tax, NMIAL has considered the following:
• 30% of non-aeronautical income which was reduced while calculating the ARR and corresponding
aeronautical revenues streams, are added back to reflect the comprehensive aeronautical revenues
for the airport.
• Aeronautical O&M expenses
• Premium (revenue share) as mentioned in clause 26.2.4 of the CA is not considered as expenditure.
• Depreciation has been considered based on regulatory books of accounts.
• Interest cost has been considered based on regulatory books of accounts (i.e. RAB * Avg. cost of
debt * 48% gearing ratio)
10.1.3 Estimated tax proposed by NMIAL, based on building blocks as per MYTP submission is as detailed
below:
Table 160: Aeronautical taxes submitted by NMIAL for the First Control Period

10.2 Authority’s examination regarding aeronautical taxation for the First Control Period
10.2.1 The Authority notes that NMIAL has considered 30% NAR in the estimation of aeronautical Profit
Before Tax (PBT), which was then used in the computation of aeronautical taxes. The fact that a part
of NAR is used for cross subsidisation as per the hybrid till mechanism does not change the nature of
such revenue to aeronautical. Further, the cross subsidisation as per the hybrid till mechanism is done
in order to reduce tariff pressure on passengers and to incentivize NMIAL to make effective investments
in non-aeronautical income generating sources.
10.2.2 Authority also notes that for the purpose of tax calculation, NMIAL has considered interest cost in
proportion of notional gearing ratio.
10.2.3 Therefore, the Authority is of the view that:
Consultation Paper No. 08/2025-26 Page 180 of 202TAXATION FOR THE FIRST CONTROL PERIOD
• 30% NAR should not be treated as a subsidy for NMIAL as NMIAL has already earned it from
non-aeronautical services and is meant as a cross subsidy to the airport user.
• The consideration of 30% NAR as part of revenue from aeronautical services would result in an
unfair enrichment to NMIAL, effectively reducing the cross-subsidy benefit to the airport user from
the present 30% non-aeronautical income.
10.2.4 Therefore, the Authority proposes to consider only aeronautical revenue and expenses in the calculation
of aeronautical PBT.
10.2.5 The Authority has directed NMIAL to submit annual tariff proposal (tariff rate card) withing 7 days
from issue of this Consultation Paper which will be reviewed and put up for Stakeholder Consultation.
Further the Authority has issued the Ad-hoc order for NMIA. For calculation of tax the Authority has
proposed to consider 5% Y-o-Y increase in rates from the rates in Ad-hoc order. This calculation will
be revised in the Tariff Order based on rates approved at that time.
10.2.6 Also, the Authority has recomputed the aeronautical tax of NMIAL based on the changes proposed to
the other building blocks and based on the proposal discussed above on exclusion of NAR.
10.2.7 Based on the above, the following table summarizes the aeronautical taxes proposed by the Authority
for the First Control Period.

Consultation Paper No. 08/2025-26 Page 181 of 202QUALITY OF SERVICE FOR THE FIRST CONTROL PERIOD
11. QUALITY OF SERVICE FOR THE FIRST CONTROL PERIOD
11.1 NMIAL’s submission regarding Quality of Service for the First Control Period
11.1.1 NMIAL has submitted that it will abide by the Airport Service Quality (ASQ) performance indicators
mentioned in Annex I of Schedule I in the Concession Agreement.
11.1.2 NMIAL has summarized the service qualities on the basis of performance indicators, measures,
measurement mechanisms and measurement frequency. NMIAL has submitted that it is committed to
abide by the ASQ performance indicators mentioned in Annex I of Schedule I.
11.2 Authority’s examination regarding Quality of Service for the First Control Period
11.2.1 The Authority notes that:
• As per section 13 (1) (d) of the AERA Act, 2008, the Authority shall “monitor the set performance
standards relating to quality, continuity and reliability of service as may be specified by the Central
Government or any Authority authorized by it in this behalf.”
• As per section 13(1)(a)(ii), the Authority is required to determine the tariff for aeronautical services
taking into consideration “the service provided, its quality and other relevant factors.”
11.2.2 The Authority notes that Annex I of Schedule I of the CA for NMIA lays down the following:
“The subjective quality of service shall be measured on the parameter of "Overall satisfaction with the
airport" on the ACI ASQ survey to be conducted every quarter. The benchmark score for the parameter
"Overall satisfaction with the airport" shall be at least equivalent to such score that the Airport is
identified within top 20 (twenty) percentile of all airports in its category in the world. The
Concessionaire shall also provide performance on all measured parameters of the ACI ASQ survey as
part of the Monthly Statement being submitted as per the provisions of ARTICLE 20 of the Agreement.”
11.2.3 The Authority also notes the clause 22.7.1 of the Concession Agreement that states, NMIAL shall
participate in the user survey of ASQ undertaken by ACI or any substitute thereof, conducted every
quarter and ensure that the airport achieves and maintains a rating of at least 4.50 (four point five) out
of 5.00 (five) and / or shall appear within top 20 (twenty) percentile of all airports, in its category in the
world in such survey within 5 (five) years from the phase I COD and maintain the same throughout the
rest of the concession period.

12.2 Authority’s examination regarding ARR for the First Control Period
12.2.1 The observations and proposals of the Authority across the regulatory building blocks impact the
computation of ARR and Yield. The Authority proposes to consider the regulatory building blocks
as discussed in the previous chapters with respect to each element of the regulatory building blocks
considered by NMIAL, in computation of ARR and Yield in the table above.
12.2.2 The Authority is of the view that when a new airport is constructed, it involves significant capital
investment in infrastructure, facilities, and operational costs. These costs are typically recovered
through tariffs imposed on airlines, passengers, and other users of the airport's services. However,
setting tariffs at excessively high levels can potentially discourage airlines from operating at the
airport and deter passengers from choosing it as their preferred gateway. Conversely, setting tariffs
too low may result in inadequate revenue generation, making it challenging for the airport to cover
its operating costs and debt obligations.
12.2.3 This requires a delicate balance between cost recovery and its potential impact on air traffic demand.
This balance is crucial for the financial viability of the airport and its ability to sustain operations
while also ensuring that the tariffs remain competitive enough to attract and retain airlines and
passengers. Therefore, the Authority, based on the tariff rate card to be submitted by NMIAL, will
decide the balance between cost recovery and its potential impact on air traffic demand.
Consultation Paper No. 08/2025-26 Page 184 of 202AGGREGATE REVENUE REQUIREMENT FOR THE FIRST CONTROL PERIOD
12.2.4 The Authority also draws reference to the guiding principles issued by the International Civil
Aviation Organization (ICAO) on charges for airports and Air Navigation Services (ICAO doc
9082), which lays down the main purpose of economic oversight which is to achieve a balance
between the interest of airports and the airport users. This policy document categorically specifies
that “caution be exercised when attempting to compensate for shortfalls in revenue considering its
effects of increased charges on aircraft operator and end users”. The said policy document also
emphasizes balancing the interests of airports on one hand and aircraft operators, end users on the
other, in view of the importance of the air transport system to States. The Authority’s objective is
to strike a balance between reasonable collections for the airport operator and tariffs for airlines and
passengers.
12.2.5 The Authority also brings notice to para 12 (c) of the National Civil Aviation Policy (NCAP) 2016,
in case the tariff in one particular year or contractual period turns out to be excessive, the airport
operator and regulator will explore ways to keep the tariff reasonable and spread the excess amount
over future through its order no 14/2016-17 dated January 12, 2017.
