Tata Power Renewable Energy, a subsidiary of The Tata Power Company, has signed its first Battery Energy Storage Purchase Agreement (BESPA) with NHPC for a standalone battery energy storage system (BESS) in Kerala.

The 30 MW / 120 MWh project, secured under NHPC’s BESS Tranche-I tender through competitive bidding, will be developed at the 220 kV substation in Kerala. Kerala State Electricity Board (KSEB) will be the end user of the storage asset.

The project aims to address peak power demand, improve grid flexibility, and facilitate the integration of renewable energy into Kerala’s power mix. It is part of NHPC’s broader plan to develop 125 MW / 500 MWh of standalone BESS in the state, under a Tariff-Based Competitive Bidding framework supported by Viability Gap Funding.

The initiative aligns with the Government of India’s target to achieve 500 GW of non-fossil fuel energy capacity by 2030. Commissioning is expected within 15 months, with the project operating under a 12-year BESPA in line with Ministry of Power guidelines.

This project marks TPREL’s first standalone BESS win and adds to its growing renewable portfolio. The company is also executing a 100 MW solar project integrated with 120 MWh of storage in Rajnandgaon, Chhattisgarh, under an EPC contract from the Solar Energy Corporation of India.

With this addition, TPREL’s total renewable capacity stands at approximately 10.9 GW, including 5.6 GW of operational assets (4.6 GW solar and 1 GW wind) and 5.3 GW under development.
