The Union Cabinet, chaired by the Prime Minister Narendra Modi, has approved the Green Energy Corridor Phase-III (GEC-III) scheme. This, the government has termed as a “historic” initiative, which is expected to strengthen India’s Intra-State Transmission System (InSTS) to enable evacuation of up to 135 GW of renewable energy across states and union territories.


The scheme also provides for deployment of 50 GWh of Battery Energy Storage Systems (BESS) at the renewable energy developer or generator end or any other location of importance for grid flexibility to address intermittency, congestion, peak-hour curtailment and meet non-solar hour demand.


The scheme will facilitate grid integration and power evacuation within the states and union territories. GEC-III is targeted to be set up by FY 2032-33 with total project outlay of ₹1,86,405 crore, comprising ₹1,36,378 crore for the development of Intra-State Transmission Systems (InSTS) under GEC-III and ₹50,000 crore for 50 GWh of BESS.


It involves a total Central Financial Support of ₹54,082 crore. The Central Financial Assistance (CFA) will help in offsetting the Intra-State transmission charges to help keep the power costs down, ultimately benefiting the end users.
