**Executive Summary**
This document presents the Minister of New and Renewable Energy's response to questions raised regarding the installation of rooftop solar (RTS) plants and waste-to-energy (WTE) facilities. The response includes data on RTS capacity installed in government buildings in Punjab, Haryana, and Chandigarh as of October 31, 2025, and across the country as of November 4, 2025. It also addresses the status of the WTE plant at Dadumajra and future plans for waste processing.
**Key Points / Main Content**
* **Rooftop Solar (RTS) Installation:**
* As of October 31, 2025, an aggregate of 22.42 GW rooftop solar capacity has been installed in the country by different categories of consumers.
* The following RTS installations in government buildings were reported by the agencies of Punjab, Haryana, and UT of Chandigarh:
* Chandigarh: 6,606 buildings with 52.825 MW capacity
* Haryana: 241 buildings with 4.82 MW capacity
* Punjab: 4,474 buildings with 34 MW capacity
* As of November 4, 2025, an aggregate of 619.78 MW rooftop solar capacity has been installed on 13,525 government buildings across the country.
* **Coercive Measures for RTS Installation:**
* The Ministry of New and Renewable Energy has not issued any directions to state/UT agencies for taking coercive measures (e.g., amendments to building bylaws) to compel the installation of RTS plants.
* **Waste-to-Energy (WTE) Plant at Dadumajra:**
* The Municipal Corporation of Chandigarh (MCC) reports that wet and dry waste are already being processed at the Dadumajra site, where it is being converted into Refuse-Derived Fuel (RDF), a recognized form of Waste-to-Energy (WTE) processing.
* The plant was taken over by MCC in 2020 and is being operated with 200 MTD dry waste processing, along with a mixed-waste processing facility.
* A Memorandum of Understanding (MoU) has recently been signed between MCC and Indian Oil Corporation Ltd. for setting up a segregated organic Municipal Solid Waste-based Compressed Bio Gas plant at the Dadumajra dumping ground to process around 230 MTD of waste.
**Impact Analysis**
**State/UT Agencies (Punjab, Haryana, Chandigarh)**
* **Impact:** The agencies have reported the installation of RTS plants in their respective territories.
* **Action Required:** No specific action is mentioned, but continued monitoring and reporting of RTS installations may be expected.
**Municipal Corporation of Chandigarh (MCC)**
* **Impact:** The MCC is responsible for waste processing at the Dadumajra site.
* **Action Required:** Continue operating the existing waste processing facilities and proceed with the establishment of the segregated organic Municipal Solid Waste-based Compressed Bio Gas plant in collaboration with Indian Oil Corporation Ltd.
**Central Ministries/Departments**
* **Impact:** These entities are contributing to the overall RTS capacity installation in government buildings.
* **Action Required:** No specific action is mentioned, but continued adoption of RTS plants may be expected.

of Punjab, Haryana, UT of Chandigarh and Central Government offices along with the number
of buildings which have been solarised and the details of total installed capacity building-wise;

waste- processing facility at Dadumajra to eliminate the waste mountain and if so, the details
thereof?
ANSWER
THE MINISTER OF STATE FOR NEW & RENEWABLE ENERGY AND POWER
(SHRI SHRIPAD YESSO NAIK)
(a) As on 31.10.2025, an aggregated 22.42 GW rooftop solar (RTS) capacity has been installed
in the country by different categories of consumers.
The agencies of state of Punjab and Haryana and UT of Chandigarh have reported installation
of RTS plants in Government buildings as per details given below:
State/UT Number of Total RTS
Government capacity installed
buildings (in MW)
Chandigarh 6,606 52.825
Haryana 241 4.82
Punjab 4,474 34An aggregate 619.78 MW capacity rooftop solar has been installed on 13,525 government
buildings of various Central Ministries/Departments across the country, as on 04.11.2025.
(b) The Ministry of New and Renewable Energy has not issued any directions to the state/UT
agencies for taking coercive measures such as amendments to building bylaws threatening
cancellation of registration or conveyance deeds to compel installation of RTS plants.
(c) & (d) The Municipal Corporation of Chandigarh (MCC) has reported that wet and dry waste
are already being processed at the Dadumajra site, where the material is being converted into
Refuse-Derived Fuel (RDF), which itself is a recognized form of Waste-to-Energy (WTE)
processing. For several years, the plant remained under litigation, preventing the MCC from
undertaking any major restructuring or establishing an alternative full-scale WTE facility.
Meanwhile, the plant was taken over by MCC in 2020 and is being operated with 200 MTD dry
waste processing, along with a mixed-waste processing facility.
In addition, a Memorandum of Understanding (MoU) has been recently signed between MCC
and Indian Oil Corporation Ltd. for setting up a segregated organic Municipal Solid Waste–
based Compressed Bio Gas plant at the Dadumajra dumping ground to process around 230 MTD
of waste.
