Reliance Power Limited's subsidiary, Reliance NU Suntech Private Limited, has signed a landmark 25-year Power Purchase Agreement (PPA) with the Solar Energy Corporation of India (SECI), a premier Navratna Central Public Sector Enterprise. This long-term agreement marks one of India’s most significant clean energy commitments to date and reinforces the country’s strategic push toward sustainable power.
Under this agreement, Reliance NU Suntech will develop and commission Asia’s largest integrated solar and battery energy storage system (BESS) at a single location within 24 months. The project represents a capital investment of up to ?10,000 crore and is aligned with India’s ambitious renewable energy goals. It also cements Reliance Power’s position as a major contributor to the nation’s green energy transition.
The PPA covers the supply of 930 MW of solar power, backed by a 465 MW/1,860 MWh BESS, at a competitive fixed tariff of ?3.53 per kWh. To meet this capacity, the project will install over 1,700 MWp of solar generation infrastructure. This agreement is a cornerstone of Reliance Power’s long-term strategy to lead India’s shift to affordable, clean, and sustainable energy.
In December 2024, Reliance NU Suntech emerged as the top winner in SECI’s Tranche XVII auction, securing the largest allocation: 930 MW of solar capacity with 465 MW/1,860 MWh of BESS. The allocation followed a highly competitive, tariff-based bidding process that drew participation from five major energy firms vying for 2,000 MW of ISTS-connected solar projects and 1,000 MW/4,000 MWh of BESS capacity—underscoring the scale and importance of this achievement.
Reliance NU Suntech has already submitted a Performance Bank Guarantee of ?378 crore to SECI. The entire bidding process—from the reverse auction and issuance of the Letter of Award (LoA) to the finalization of the PPA—was completed in under five months. This swift execution reflects Reliance Power’s operational excellence, decade-long track record, and steadfast commitment to accelerating India’s clean energy transition.
