India Approves Rs 1.86 Lakh Crore Green Energy Corridor Phase-III for 135 GW Renewable Power
  • •Union Cabinet approves Rs 1.86 lakh crore Green Energy Corridor Phase-III (GEC-III) to build transmission infrastructure for 135 GW renewable power and deploy 50 GWh battery storage.
  • •The scheme aims to prepare India's power grid for a sharp increase in renewable energy capacity, particularly solar and wind, by ensuring efficient transmission and storage.
  • •GEC-III includes Rs 1,36,378 crore for intra-state transmission systems and Rs 50,000 crore for 50 GWh Battery Energy Storage Systems (BESS), with Rs 54,082 crore central financial assistance.
  • •Battery storage systems will address intermittency, transmission congestion, peak-hour curtailment, and electricity demand during non-solar hours, balancing supply and demand.
  • •The project is crucial for India's target of 500 GW non-fossil fuel capacity by 2030, ensuring grid infrastructure keeps pace with renewable energy additions and reduces curtailment risk.

Key Questions Answered

The Union Cabinet approved a total project outlay of Rs 1,86,405 crore for Green Energy Corridor Phase-III, which is targeted for completion by FY2032-33.

All new or greenfield intra-state transmission projects under GEC-III will be awarded via tariff-based competitive bidding, while existing brownfield networks requiring upgrades will be carried out on a cost-plus basis.

The scheme supports deploying 50 GWh of battery storage to address intermittency in renewable generation, transmission congestion, peak-hour curtailment, and electricity demand during non-solar hours.
