Reliance NU Suntech to Build Asia's Largest Solar and Battery Project

Reliance NU Suntech, a part of Anil Ambani’s Reliance Power, has signed a major 25-year deal with the Solar Energy Corporation of India (SECI) to create Asia’s biggest solar and battery storage project. Worth up to Rs 10,000 crore, this game-changing project is expected to be up and running within two years, helping India take a big step toward clean energy.

The project will produce 930 MW of solar power and include a 465 MW/1,860 MWh battery storage system, which can provide steady power for four hours during peak times. To make this happen, Reliance NU Suntech will install over 1,700 MWp of solar panels, secured at a fixed rate of Rs 3.53 per kWh. The company won this opportunity in December 2024 through SECI’s Tranche XVII auction, beating out four other energy companies in a competitive bidding process for 2,000 MW of solar projects connected to the national grid and 1,000 MW/4,000 MWh of battery storage.

Reliance Power showed its commitment by submitting a Rs 378 crore Performance Bank Guarantee to SECI. After the announcement, the company’s stock price jumped nearly 3.9% to Rs 41.54 on the Bombay Stock Exchange, showing strong support from investors.

Through this project India advances its renewable energy initiatives via programs such as the PM Surya Ghar Muft Bijli Yojana that achieved the installation of 5.21 GW of rooftop solar in the previous year. The successful implementation of this project requires solving power grid stability issues and storage solution integration to provide dependable electricity.

Anil Ambani, Chairman of Reliance Power, called the project a “huge win” for India’s clean energy future. “This PPA positions Reliance NU Suntech as a leader in Asia’s renewable energy sector, driving innovation and sustainability,” he said. The project will supply power to various distribution companies across India, strengthening Reliance Power’s role in the country’s energy transformation.
