## 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 Government buildings   |   Total RTS capacity installed (in MW) |
|------------|----------------------------------|----------------------------------------|
| Chandigarh | 6,606                            |                                 52.825 |
| Haryana    | 241                              |                                  4.82  |
| Punjab     | 4,474                            |                                 34     |

An 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.
