New Delhi: Tata Power Renewable Energy Ltd (TPREL), a subsidiary of Tata Power, has signed its first standalone battery energy storage purchase agreement (BESPA) with NHPC Ltd to develop a 30 MW/120 MWh battery energy storage system (BESS) for Kerala State Electricity Board (KSEB), the company announced on Friday.
The project was awarded under NHPC’s Tranche-I battery storage tender via tariff-based competitive bidding. The BESS will be located at a 220 kV substation in Kerala and is part of NHPC’s broader effort to deploy 125 MW/500 MWh of standalone storage capacity in the state.
The project will operate under a 12-year contract and is supported by the government’s Viability Gap Funding (VGF) scheme. Developed in line with Ministry of Power guidelines, it is expected to be commissioned within 15 months.
Tata Power said the system will help meet Kerala’s peak demand requirements, enhance grid flexibility, and integrate variable renewable energy sources. It also aligns with India’s national goal of installing 500 GW of non-fossil fuel capacity by 2030.
This contract marks TPREL’s debut in the standalone BESS segment. The company already operates a solar-plus-storage project in Rajnandgaon, Chhattisgarh, comprising a 100 MW solar PV plant with a 120 MWh utility-scale BESS, developed under an EPC contract for SECI.
With this new project, TPREL’s total renewable capacity has reached 10.9 GW — including 5.6 GW in operation (4.6 GW solar, 1 GW wind) and 5.3 GW under development.
Tata Power, the parent company, manages a 15.7 GW power portfolio spanning generation, transmission, distribution, trading, storage, and solar module manufacturing. Of this, 6.9 GW (44 percent) is clean energy. The company aims to achieve carbon neutrality before 2045.
