It is the first Battery Energy Storage Purchase Agreement (BESPA) that Tata Power Renewable Energy Limited (TPREL), a subsidiary of Tata Power, has signed with NHPC Limited to develop a 30 MW / 120 MWh battery energy storage system at a 220 kV substation in Kerala. Under the competitive bidding system of NHPC in its BESS Tranche-I tender, the project was awarded to the company and would be powering the Kerala State Electricity Board Limited.
The battery energy storage system will contribute to solving peak power demand, enhancing grid flexibility, and allowing renewable energy integration in Kerala. The proposed project is one of many that NHPC intends to complete to generate 125 MW / 500 MWh of standalone battery with the provision of Viability Gap Funding through a Tariff-Based Competitive Bidding model in the state.
The project, which is in line with the Indian planned target of having 500 GW of non-fossil fuel capacity by 2030 will be done under a 12 year BESPA, and is projected to be commissioned in 15 months.
The acquisition also represents TPREL participation in the independent battery storage market, which further enhances its renewable energy totals that have now grown to about 10.9 GW, consisting of 5.6 GW available capacity and 5.3 GW in development.
The company has already connected a 100 MW solar plant combined with a 120 MWh battery storage unit at Chhattisgarh.
Tata Power, which holds a total portfolio of 15.7 GW in generation, transmission, distribution and storage, has remained at the forefront of clean energy transition in India and is determined to reach carbon neutrality by 2045.
