Tata Power Renewable Energy Ltd (TPREL) has won its first Battery Energy Storage Purchase Agreement (BESPA) with a 30 MW / 120 MWh project awarded by NHPC for deployment in Kerala. This battery system, to be set up at a 220 kV substation, will provide four hours of backup power and support Kerala State Electricity Board's grid needs. Operating under a 12-year contract, the project will enhance grid stability and enable greater renewable integration. Part of NHPC's broader 125 MW / 500 MWh BESS plan, the initiative supports India's 500 GW non-fossil fuel goal for 2030. TPREL's total renewable capacity now stands at 10.9 GW.
Tata Power Renewable Energy Ltd (TPREL) has secured a 30 megawatt (MW) / 120 megawatt-hour (MWh) battery energy storage system (BESS) project from state-owned NHPC. This marks TPREL's first Battery Energy Storage Purchase Agreement (BESPA), signifying a new milestone in its clean energy journey. Advertisement
The project was secured under NHPC's BESS Tranche-I tender through a competitive bidding process. The Kerala State Electricity Board Ltd (KSEBL) will be the end-user of this Battery Energy Storage System (BESS) asset. The initiative involves setting up a 30 MW / 120 MWh battery storage system at a 220 kV substation in Kerala. This capacity means the 30 MW storage can provide backup power for up to four hours, a crucial capability for grid stability.
Battery Energy Storage Systems are advanced technological solutions designed to store electrical energy from various sources-including intermittent renewables like solar and wind-for later use. They play a vital role in balancing the electric grid, providing backup power, and improving grid stability by addressing supply-demand gaps and frequency fluctuations.
The project will operate under a 12-year BESPA and is slated for commissioning within 15 months. Its deployment positions energy storage as a key enabler of round-the-clock renewable power and enhanced grid resilience. The system is expected to play a vital role in addressing peak power demand, significantly enhancing grid flexibility, and enabling the seamless integration of larger volumes of renewable energy into Kerala's power grid.
This project forms part of NHPC's broader initiative to develop 125 MW / 500 MWh of standalone battery storage capacity within Kerala. This larger program is being implemented under a Tariff-Based Competitive Bidding framework, supported by Viability Gap Funding from the government. The initiative aligns directly with the Government of India's ambitious target of achieving 500 GW of non-fossil fuel capacity by 2030, underscoring the national commitment to a sustainable energy transition.
With this latest addition, TPREL's total renewable capacity now stands at approximately 10.9 GW. This portfolio includes 5.6 GW of operational projects, comprising 4.6 GW of solar and 1 GW of wind power, along with 5.3 GW currently under various stages of development. TPREL has also notably commissioned a record 752 MW of solar capacity in the first quarter of the current fiscal year. Beyond this new project, TPREL is already operating a solar and BESS project in Rajnandgaon, Chhattisgarh, demonstrating its existing expertise in integrated storage solutions. Tata Power, TPREL's parent company, has a diversified portfolio of 15.7 GW spanning the entire power value chain and is committed to achieving carbon neutrality before 2045.
