The proposed Telangana BESS project comes amid growing requirements for flexible electricity infrastructure to accommodate variable renewable generation. Battery storage systems can store electricity when supply is available and discharge it when demand rises or renewable generation declines. Such capabilities can help balance supply and demand, improve grid flexibility and support the reliable integration of solar and wind power.
Through this tender, POWERGRID is advancing the development of large-scale battery storage infrastructure. The project represents another step towards strengthening India’s electricity network and meeting the operational requirements of a power system increasingly supported by renewable energy sources.
