Reliance Power Locks In PPA for Asia’s Largest Solar-Storage Hub

• Reliance NU Suntech secures a 25-year PPA with SECI to build Asia’s largest 930 MW solar and 465 MW/1,860 MWh battery storage complex by 2027.

Reliance NU Suntech, a subsidiary of Reliance Power Ltd, has clinched a landmark 25-year power purchase agreement with the Solar Energy Corporation of India (SECI). The deal tasks Reliance with building what promises to be Asia’s biggest integrated solar-plus-storage facility—930 MW of solar panels paired with 465 MW/1,860 MWh of on-site batteries—at a fixed tariff of INR 3.53 (USD 0.042/EUR 0.037) per kilowatt-hour.

The reverse auction win in December set the wheels in motion. Over the next two years, Reliance NU Suntech will install more than 1,700 MWp of photovoltaic capacity across a sprawling site, funded by up to INR 100 billion in capital investment. The company has already posted a Performance Bank Guarantee of INR 3.78 billion, clearing the final regulatory hurdle before ground breaks.

“Pairing solar generation with battery storage lets us smooth out the sun’s ups and downs and deliver power round-the-clock,” said a Reliance spokesperson. “This project is a game-changer for India’s clean-energy ambitions.” With commissioning targeted for late 2027, SECI will be able to dispatch emissions-free electricity even after sunset, reducing reliance on fossil-fuel peaker plants and bolstering grid stability.

India’s renewable sector has exploded in recent years, thanks to plunging hardware costs and aggressive government targets. Hybrid projects like this one earn a premium by guaranteeing delivery during peak evening hours when demand soars. Experts say these large-scale integrations are key to hitting India’s 500 GW renewable milestone by 2030.

Local communities stand to benefit as well. Thousands of jobs will be created during construction and operations, and landowners will secure long-term lease revenue. Reliance also plans to invest in nearby infrastructure and vocational training programs, spreading economic gains beyond the plant footprint.

As Asia’s largest single-site solar-plus-storage project moves from blueprint to reality, Reliance NU Suntech is positioning itself at the forefront of the nation’s green energy transition. With this PPA in hand, the company—and the country—edges closer to a cleaner, more reliable power future.
