Solar Energy Corporation of India Limited (SECI) has entered into a battery energy storage sale agreement with Kerala State Electricity Board (KSEB) for a grid-connected standalone battery energy storage system (BESS) project of 125 MW/500 MWh capacity. The project will be developed, operated, and maintained by JSW Energy, which secured the project through a competitive auction conducted by SECI at a tariff of Rs 441,000 per MW per month.
The BESS is intended to be available for KSEB to charge and discharge on an on-demand basis, enabling the state utility to manage its grid requirements efficiently. Additionally, the project is eligible for viability gap funding.
In September 2024, KSEB and SECI signed an agreement to procure 500 MW of solar power at Rs 3.49 per unit for 25 years starting September 2026, aiming to reduce power purchase costs by at least 10 per cent.
