India Approves $22 Billion Green Energy Corridor Expansion

GEC-III to Support 135GW of Renewable Energy

India’s federal cabinet has approved the third phase of the Green Energy Corridor (GEC-III), with planned investment of INR 1.86 trillion (about $22 billion). The program is designed to strengthen intra-state transmission networks and support the integration of up to 135GW of renewable energy.

The plan is targeted for completion by the 2032–33 financial year, including INR 1.36 trillion for transmission infrastructure and INR 500 billion for battery energy storage systems (BESS).

50GWh Battery Storage Planned

GEC-III will also deploy 50GWh of BESS at renewable energy project sites and strategically important grid locations.

The storage capacity is expected to improve grid flexibility, manage renewable generation fluctuations, reduce transmission congestion and limit renewable energy curtailment. It will also help supply electricity during periods without solar generation and support peak demand.

Tackling India’s Grid Bottleneck

Transmission constraints have become a growing challenge as India rapidly expands renewable generation. According to Ember data cited in the report, India curtailed around 300GWh of renewable electricity in the first quarter of 2026, accounting for nearly two-thirds of the country’s total curtailment.

GEC-III is part of India’s broader effort to expand transmission capacity and support its long-term target of 900GW of non-fossil power capacity by 2035.
