The Solar Energy Corporation of India (SECI) has announced its intent to procure power from an aggregate 2 GWh capacity of standalone energy storage systems. The agency will issue the tender to set up the capacity by August 31.
The energy storage system projects will be set up on a build-own-operate basis. SECI shall sign a 25-year agreement with the successful bidders.
India has reached 96.95 GW of cumulative grid-interactive renewable energy capacity (excluding large hydro) as of June 30, 2021, and is aiming for 450 GW by 2030.
With the increasing penetration of variable RE in the grid, the nation needs to accelerate the deployment of utility-scale battery storage to ensure grid stability. The battery storage can store the renewable power when it is available in excess and supply firm power later when generation is low, but demand is high.
SECI leads the way for utility-scale battery deployment by coming up with RE plus battery storage auctions that mandate round-the-clock RE power supply. The standalone energy storage system project of 2 GWh is the latest in this series.
Recently, state-run power producer NTPC had also invited an Expression of Interest (EoI) from Indian and global firms to set up 1 GWh of grid-scale battery energy storage system (BESS) at its power plants in India. The BESS may be deployed at a single location or split across multiple NTPC power plants.
