Cabinet approves Green Energy Corridor Phase-III with battery storage
The Union Cabinet, chaired by Prime Minister Narendra Modi, approved the Green Energy Corridor Phase-III (GEC-III) scheme on 30 September 2026. It will strengthen the intra-State transmission system (InSTS) so that up to 135 gigawatts (GW) of renewable energy can be evacuated across States and Union Territories. It also provides for 50 GWh of Battery Energy Storage Systems (BESS).
Scheme at a glance
| Item | Detail |
|---|---|
| Transmission capacity | Evacuation of up to 135 GW of renewable energy |
| Storage | 50 GWh of battery energy storage systems |
| Target | By FY 2032-33 |
| Total outlay | ₹1,86,405 crore, as stated in the release |
| Transmission component | About ₹1.36 lakh crore |
| Battery storage component | ₹50,000 crore |
| Central Financial Support | ₹54,082 crore |
Greenfield transmission projects will be built through tariff-based competitive bidding (TBCB), while brownfield upgrades will be done on a cost-plus basis. State Transmission Utilities are the overall implementing agencies, and Transmission Service Providers take part on a Build-Own-Operate-Maintain (BOOM) model.
The central assistance helps offset intra-State transmission charges, which keeps power costs down for consumers. The scheme supports the target of 900 GW of non-fossil installed capacity by 2035. BESS can be placed at the renewable developer or generator end, or at any other location that matters for grid flexibility, to manage intermittency, congestion and peak-hour curtailment.
Why it matters for exams
Energy-sector schemes, GW and GWh units and the non-fossil target are typical current affairs and economy questions for TNPSC and general awareness questions in banking exams. Revise them with the TNPSC current affairs guide.
