Reliance Power has entered the renewable energy and storage sector as it has bagged a tender from the Solar Energy Corporation of India (SECI) to set up a 500 MW/1000 MWh battery energy storage system (BESS). This project was awarded through SECI’s e-Reverse Auction (eRA), held on September 11, according to sources familiar with the development. The overall contract involves setting up 1,000 MW/2,000 MWh of standalone BESS units, awarded on a build, own, and operate (BOO) basis, designed for “on-demand” usage under a tariff-based competitive bidding process. Reliance Power won half of the total capacity, securing 500 MW/1000 MWh, while the remaining 500 MW/1000 MWh was awarded to a subsidiary of JSW Energy, the sources added.
