SHRI C N ANNADURAI:
SHRI SELVAM G:
Will the Minister of POWER
be pleased to state:
(a) whether the Government has prepared a long-term plan to augment power
generation capacity in Tamil Nadu to meet the State's projected electricity
demand up to the year 2034-35 and if so, the details thereof;
(b) the details of thermal power generation projects under construction or
approved in Tamil Nadu including their proposed capacity, estimated cost and
expected year of commissioning;
(c) whether the Government has assessed the requirement of additional
thermal power capacity for Tamil Nadu and if so, the details thereof along with
the steps taken to facilitate timely implementation of the proposed projects;
(d) the measures being taken to ensure adequate coal supply, transmission
infrastructure and environmental compliance for these projects; and
(e) the expected impact of the proposed capacity addition on power
availability, industrial growth, agricultural supply and long-term energy
security in Tamil Nadu?

THE MINISTER OF STATE IN THE MINISTRY OF POWER
(SHRI SHRIPAD NAIK)
(a) : Ministry of Power had notified the Electricity (Amendment) Rules in
December, 2022. Under Rule 16 of the Electricity (Amendment) Rules, Ministry
of Power has notified ‘Resource Adequacy (RA) Guidelines’ in June, 2023.
With a view to ensure generation capacity remains ahead of projected
peak demand, all the Discoms / States including Tamil Nadu, in consultation
with Central Electricity Authority (CEA), have prepared their “Resource
Adequacy Plans (RAPs)” till 2035-36, which are dynamic ten-year rolling plans
and includes power generation as well as power procurement planning, in
accordance with the above-mentioned guidelines.
………2.- 2 -
(b) : The details of the under-construction and proposed thermal power
projects in the State of Tamil Nadu are given at Annexure-I and Annexure-II
respectively.
(c) : As per the Resource Adequacy Plan (RAP) of Tamil Nadu till 2035-36,
about 12,400 MW additional thermal capacity is required by 2034-35. Of these,
2,640 MW thermal capacity is under-construction in the State, 1000 MW thermal
capacity is under bidding, and further, for setting up 660 MW thermal capacity,
Notice Inviting Tender (NIT) has been issued. Tamil Nadu may either set up the
balance capacity or tie up power from generation projects located within or
outside the state.
Ministry of Power through Central Electricity Authority (CEA) monitors
the progress of under-construction power projects through frequent site visits
and interaction with the developers and other stakeholders for resolving issues
critical for projects commissioning.
(d) : The following steps are being taken to ensure uninterrupted coal supply
to power plants:
i. To address the issues of coal supplies to power sector, an Inter-
Ministerial Sub Group comprising of representatives from Ministries of
Power, Coal, Railways, Central Electricity Authority (CEA), Coal India
Limited (CIL) and Singareni Collieries Company Limited (SCCL) meet
regularly to take various operational decisions to enhance supply of coal
to thermal power plants as well as for meeting any contingent situations
relating to power sector including to alleviate critical coal stock position
in power plants.
ii. An Inter-ministerial Secretary-level meeting, comprising: Secretary
(Power), Secretary (Coal) and Chairman Railway Board, is held regularly
to monitor coal stocks.
iii. CCEA has approved the Revised SHAKTI Policy for Coal Allocation to
Power Sector on 07.05.2025 under which interested power plants may
participate and secure coal linkages.
In respect to transmission infrastructure, Tamil Nadu is well connected
to the National Grid through a robust Inter-State Transmission System (ISTS),
comprising 765 kV and 400 kV transmission lines as well as the ±800 kV HVDC
system, enabling reliable power transfer with other States / Regions. The
transmission network is strengthened on a continuous basis in line with
evolving power transfer requirements to ensure reliable and secure evacuation
and supply of power. Transmission systems, wherever required, are planned
based on generation proposals received from the Central or State Sector
through the established transmission planning process.
……….3.- 3 -
The intra state transmission system (InSTS) has already been planned for
evacuation of power from the under-construction thermal projects viz. Ennore
SEZ (2x660 MW) and Udangudi STPP (2x660 MW).
Environment Clearance (EC), which is granted by Ministry of Environment,
Forest and Climate Change (MoEF&CC), is the foremost requirement for
establishment of new as well as expansion of thermal power capacity. All other
clearances & permissions / approvals are processed only on the basis of grant
of Environment Clearance; which is based on an elaborate and rigorous
process. Further, the thermal power plants need to comply with emissions
standards laid down by MoEF&CC, and the compliance is monitored by
respective State Pollution Control Board (SPCB) and Central Pollution Control
Board (CPCB).
(e) : The Resource Adequacy Plan(RAP) for Tamil Nadu till 2035-36 has been
prepared considering demand projections that account for anticipated growth
across all consumer sectors, including industrial, agricultural, commercial,
domestic, and others. Based on these demand projections, the generation
capacity addition envisaged under the RAP is likely to meet the State's
projected electricity demand while ensuring energy security as far as
electricity sector is concerned.
