Cabinet approves Green Energy Corridor Phase-III scheme for Development of Intra-State Transmission System with Battery Energy Storage Systems

The Union Cabinet has approved the Green Energy Corridor Phase-III (GEC-III) scheme, aimed at developing India's Intra-State Transmission System (InSTS) for evacuating up to 135 GW of renewable energy. The scheme includes the deployment of 50 GWh of Battery Energy Storage Systems (BESS) to address grid intermittency and peak-hour demand. Set to be established by FY 2032-33 with a total outlay of Rs. 1,86,405 crore, it features a Central Financial Support of Rs. 54,082 crore to help offset transmission charges and lower power costs. Greenfield projects will be implemented via Tariff Based Competitive Bidding, while State Transmission Utilities act as the overall implementing agency. The initiative supports India's target of 900 GW installed non-fossil capacity by 2035.
