Reliance Power Limited, through its subsidiary Reliance NU Suntech Private Limited, has signed a 25-year Power Purchase Agreement (PPA) with the Solar Energy Corporation of India (SECI). This marks one of India’s largest long-term clean energy agreements to date, supporting the country’s renewable energy ambitions.
Under the agreement, Reliance NU Suntech will develop Asia’s largest single-location integrated solar and battery energy storage system (BESS) project. The project, with a planned investment of up to ₹10,000 crore, is set for commissioning within the next 24 months.
Project Highlights: 930 MW Solar Power and 465 MW BESS
The PPA involves supplying 930 megawatts (MW) of solar power integrated with a 465 MW/1,860 megawatt-hour (MWh) battery energy storage system at a fixed tariff of ₹3.53 per kilowatt-hour (kWh). To meet the contracted supply, over 1,700 MWp of installed solar generation capacity will be deployed.
This agreement supports Reliance Power’s strategy of offering sustainable and cost-effective energy solutions and positions it as a key contributor to India’s clean energy transition.

Successful Bid and Rapid Execution
Reliance NU Suntech secured this major project in December 2024 during SECI’s Tranche XVII auction, where it emerged as the largest winner by bagging 930 MW of solar power capacity and associated battery storage. The auction saw intense competition, with five leading energy firms vying for allocations under the Inter-State Transmission System (ISTS)-connected solar and storage program.
The company successfully submitted a Performance Bank Guarantee (PBG) of ₹378 crore and completed the entire bidding and agreement process—from the reverse auction to the signing of the PPA—in under five months.
Strengthening Reliance Power’s Renewable Energy Portfolio
Reliance Power, part of the Reliance Group, operates a total generation capacity of 5,305 MW, including the 3,960 MW Sasan Power project, the world’s largest integrated coal-based power plant. This new venture underlines Reliance Power’s expanding focus on green energy, reinforcing its commitment to scaling clean power solutions across India.
