Tata Power Renewable Energy Limited (TPREL), a subsidiary of The Tata Power Company Limited, has signed its first Battery Energy Storage Purchase Agreement (BESPA) with NHPC Limited. The agreement covers the development of a 30 MW / 120 MWh battery energy storage system (BESS) at a 220 kV substation in Area Code, Kerala. The project, awarded under NHPC’s BESS Tranche-I tender through a competitive bidding process, will serve Kerala State Electricity Board Limited and aims to address peak power demand, enhance grid stability, and facilitate better integration of renewable energy. This initiative is part of NHPC’s larger plan to build 125 MW / 500 MWh of standalone BESS in Kerala under a Tariff-Based Competitive Bidding framework, backed by Viability Gap Funding from the Government of India.

Aligned with the national target of achieving 500 GW of non-fossil fuel capacity by 2030, the Kerala BESS project will be commissioned within 15 months and operate under a 12-year BESPA as per Ministry of Power guidelines. This marks TPREL’s first standalone BESS project, expanding its portfolio of dispatchable renewable solutions. TPREL is already operating a 100 MW solar PV plant integrated with a 120 MWh utility-scale BESS in Rajnandgaon, Chhattisgarh, developed for the Solar Energy Corporation of India. With the addition of the NHPC project, TPREL’s total renewable energy capacity has reached approximately 10.9 GW, including 5.6 GW in operation (4.6 GW solar, 1 GW wind) and 5.3 GW under various stages of development.
