Reliance Power, Renewable Energy: Anil Ambani-owned Reliance Power Limited (Reliance Power) is set to develop and commission Asia’s largest single-location integrated solar and battery energy storage system (BESS) project. The project will be built by Reliance NU Suntech Private Limited (Reliance NU Suntech), a subsidiary of Reliance Power, within the next 24 months.
The project entails a capital investment of up to Rs 10,000 crore, representing a significant strategic commitment to operational scalability and long-term value creation. For the development of this project, the company has signed a 25-year long-term Power Purchase Agreement (PPA) with the Solar Energy Corporation of India (SECI), a leading Navratna Central Public Sector Enterprise.
Reliance NU Suntech signed a Power Purchase Agreement with SECI, comprising the supply of 930 MW of solar power integrated with 465 MW/1,860 MWh Battery Energy Storage System (BESS), at a competitive fixed tariff of Rs 3.53 per kWh.
To achieve the contracted capacity of 930 MW, the project will deploy more than 1,700 MWp of installed solar generation capacity. This landmark agreement represents a significant step in Reliance Power’s long-term strategy to lead India’s transition to sustainable, low-cost energy solutions.
In December 2024, Reliance Power's subsidiary, Reliance NU Suntech, secured the largest award in SECI’s Tranche XVII auction, winning an allocation of 930 MW of solar power capacity along with a 465 MW/1,860 MWh Battery Energy Storage System.
The allocation was awarded through a tariff-based competitive bidding process, which saw participation from 5 leading energy companies competing for a total of 2,000 MW of Inter-State Transmission System (ISTS)- connected solar projects and 1,000 MW/4,000 MWh of BESS capacity. This highlights Reliance NU Suntech’s strategic commitment to executing large-scale, integrated clean energy projects.
