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

The Union Cabinet approved the Green Energy Corridor Phase-III (GEC-III) scheme to strengthen the Intra-State Transmission System (InSTS) for evacuating up to 135 GW of renewable energy across States and Union Territories. Additionally, the scheme provides for deploying 50 GWh of Battery Energy Storage Systems (BESS) to ensure grid flexibility and address power intermittency. Scheduled for completion by FY 2032-33, the project has a total outlay of Rs. 1,86,405 crore, including Rs. 54,082 crore in Central Financial Support to keep power costs down. Implementation will involve Tariff Based Competitive Bidding for greenfield projects and Cost Plus Basis for brownfield works, aiming to support India's 900 GW non-fossil capacity target by 2035.
