Three companies - Tata Power, Acme Solar, and PNC Infratech, have signed agreements with NHPC for battery energy storage systems (BESS) projects. This move aligns with India’s renewable energy push and grid stabilisation efforts.

Tata Power announced that its subsidiary Tata Power Renewable Energy Ltd. (TPREL) has signed its first Battery Energy Storage Purchase Agreement (BESPA) with NHPC. The project involves setting up a 30 MW / 120 MWh battery storage system at a 220 kV substation in Area Code, Kerala, secured under NHPC’s BESS Tranche-I tender for the Kerala State Electricity Board. The project will operate under a 12-year BESPA and is expected to be completed within 15 months. Tata Power stated, “This marks TPREL’s entry into large-scale battery energy storage solutions.”

Acme Solar, through its subsidiaries, signed BESPAs for 275 MW/550 MWh capacity across two standalone BESS projects in Andhra Pradesh, with tariffs of ?2,10,000 per MW/month for 50 MW/100 MWh and ?2,22,000 per MW/month for 225 MW/450 MWh, secured via e-reverse auction. Earlier, PNC Infratech signed an agreement for a 300 MW ISTS-connected project with an energy storage component.
