- Tata Power Renewable Energy Ltd will build a 30MW/120MWh BESS in Kerala, India, under a 12-year agreement with NHPC to support peak demand and grid flexibility.
- The project is part of NHPC’s plan for 125MW/500MWh battery storage in Kerala and supports India’s 500GW non-fossil fuel target by 2030.
Tata Power Renewable Energy Limited (TPREL), a Tata Power subsidiary, announced on Friday, July 18, that it had signed its first standalone Battery Energy Storage Purchase Agreement (BESPA) with NHPC Limited.
In addition, TPREL will set up a 30 MW/120 MWh battery energy storage system (BESS) at a 220 kV substation in Kerala. NHPC awarded the project through a competitive bidding process under its BESS tranche-I tender. The Kerala State Electricity Board (KSEB) will also use the storage asset.
Meanwhile, TPREL aims to help Kerala manage peak electricity demand by installing the battery system, enhancing grid flexibility, and improving renewable energy integration.
Furthermore, the project forms part of NHPC’s larger initiative to build 125 MW/500 MWh of standalone battery storage capacity in Kerala. The scheme operates under a tariff-based competitive bidding framework and receives support from Viability Gap Funding.
TPREL confirmed that the project will operate under a 12-year BESPA and be commissioned within 15 months. The company said the battery system will support round-the-clock renewable power supply and strengthen grid resilience in the region.
This marks TPREL’s first win in the standalone battery energy storage segment. The company is also running a solar-plus-storage project in Rajnandgaon, Chhattisgarh, which includes a 100 MW solar plant and a 120 MWh BESS, developed under a contract from the Solar Energy Corporation of India (SECI).
With this new project, TPREL has increased its total renewable energy portfolio to about 10.9 GW. This includes 5.6 GW of operational capacity—4.6 GW of solar and 1 GW of wind—and 5.3 GW under various stages of development.
