DEVELOPMENT OF BATTERY ENERGY STORAGE SYSTEMS

• Battery Energy Storage Systems (BESS) store surplus electricity (chiefly from variable Renewable Energy) and discharge during demand peaks, also providing ancillary services like frequency regulation, voltage control, and black start.
• Central to India's 500 GW non-fossil capacity by 2030 target; CEA projects a 208 GWh BESS requirement by 2030.
• Twin policy levers: demand-side VGF (deployment) + supply-side PLI-ACC (manufacturing).
