Reliance Power’s subsidiary, Reliance NU Suntech, has signed a major 25-year Power Purchase Agreement (PPA) with the Solar Energy Corporation of India (SECI). This deal is one of the biggest long-term power agreements in India, marking a big step in the country’s move toward clean energy.
The project will create Asia’s largest solar and battery storage system at a single location. Reliance NU Suntech plans to complete this project in the next 24 months with an investment of up to Rs 10,000 crore. This move will help meet India’s renewable energy goals and boost Reliance Power’s role in India’s green energy sector.

Under the deal, Reliance NU Suntech will provide 930 MW of solar power, with 465 MW of it supported by a Battery Energy Storage System (BESS) with a capacity of 1,860 MWh. The power will be sold at a fixed rate of ₹3.53 per unit (kWh). To meet this goal, the project will use over 1,700 MW of solar generation capacity. This deal is an important part of Reliance Power’s plan to lead India’s push for affordable and sustainable energy.
In December 2024, Reliance NU Suntech won the largest allocation in SECI’s Tranche XVII auction. It secured 930 MW of solar power along with 465 MW of battery storage. This was part of a competitive bidding process where five top energy companies competed for 2,000 MW of solar power and 1,000 MW/4,000 MWh of battery storage. This win shows Reliance NU Suntech’s commitment to large-scale, clean energy projects.

This quick execution highlights Reliance’s strong operational performance, leadership in the energy sector, and dedication to speeding up India’s energy transition.
