Tata Power Renewable Energy Limited (TPREL), a subsidiary of Tata Power, has signed its first Battery Energy Storage Purchase Agreement (BESPA) with NHPC Limited to set up a 30 MW / 120 MWh battery storage system at a 220 kV substation in Kerala. The project was secured through competitive bidding under NHPC’s BESS Tranche-I tender and will serve the Kerala State Electricity Board Limited.
The battery energy storage system will help address peak power demand, improve grid flexibility, and enable better integration of renewable energy in Kerala. This initiative is part of NHPC’s broader plan to develop 125 MW / 500 MWh of standalone battery storage capacity in the state under a Tariff-Based Competitive Bidding framework supported by Viability Gap Funding.
The project, aligned with India’s target of achieving 500 GW of non-fossil fuel capacity by 2030, will operate under a 12-year BESPA and is expected to be commissioned within 15 months.
This marks TPREL’s debut in the standalone battery storage segment, further strengthening its renewable energy portfolio, which now stands at approximately 10.9 GW, including 5.6 GW operational capacity and 5.3 GW under development.
The company already operates a 100 MW solar plant integrated with a 120 MWh battery storage system in Chhattisgarh.
Tata Power, with a total portfolio of 15.7 GW spanning generation, transmission, distribution, and storage, continues to spearhead India’s clean energy transition with a commitment to achieve carbon neutrality before 2045.
