India’s Union Cabinet approved the Green Energy Corridor Phase-III (GEC-III) on September 30, 2026, a 1,86,405 crore rupee (about $19.3 billion) scheme to expand intra-state transmission networks and add 50 gigawatt-hours of battery energy storage, Free Press Journal reported, citing the government announcement. The scheme is designed to evacuate up to 135 gigawatts of renewable power from states and union territories and support India’s target of 900 gigawatts of non-fossil installed capacity by 2035, Prime Minister Narendra Modi said following the Cabinet decision.
What the Green Energy Corridor Phase-III funds
The 1,86,405 crore rupee outlay splits into two main components: 1,36,378 crore rupees for intra-state transmission systems, and 50,000 crore rupees for grid-scale battery energy storage systems with a combined capacity of 50 gigawatt-hours, according to Free Press Journal and Power Technology. Of the total, 54,082 crore rupees is central financial support, structured as viability-gap funding to make projects bankable for state transmission utilities, which will serve as the primary implementing agencies.
Greenfield transmission projects will be awarded through tariff-based competitive bidding, while brownfield upgrades to existing lines will use a cost-plus methodology, Power Technology reported. A build-own-operate-maintain model is also available to private and public developers. The government said the scheme targets completion by the 2032-33 financial year.
The battery storage component addresses what the government describes as renewable-energy intermittency, transmission congestion and peak-hour curtailment, the problem of discarding solar or wind power when the grid cannot absorb it at the moment it is generated. Storage lets utilities shift that power to hours when demand is highest and solar generation has dropped off.

|---|---|
| Total project outlay | Rs 1,86,405 crore (about $19.3 billion) |
| Intra-state transmission allocation | Rs 1,36,378 crore |
| Battery energy storage systems allocation | Rs 50,000 crore (50 GWh) |
| Central financial support (viability-gap funding) | Rs 54,082 crore |
| Renewable power evacuation capacity enabled | Up to 135 GW |
| National non-fossil capacity target supported | 900 GW by 2035 |
| Targeted completion | FY 2032-33 |
Why the storage component matters for renewable energy
India’s installed renewable capacity has been expanding faster than its grid can absorb in some states, a mismatch that GEC-III is meant to address directly. India’s battery storage additions jumped 84-fold to 8.2 GWh in the first half of 2026, and the country separately awarded 1,344 MW of pumped hydro storage and its first utility-scale vanadium flow battery project earlier this year. GEC-III’s 50 GWh battery allocation would, if fully built, be several times the storage capacity added across the first half of 2026 alone, underscoring the scale of the new scheme relative to recent deployment.
The corridor expansion also follows a broader funding trend: global renewable energy investment held at $327.5 billion in the first half of 2026 as co-located solar-and-storage projects set a record, reflecting the same logic driving India’s push to pair new transmission with storage rather than transmission alone.
Modi described the approval in terms of grid reliability rather than generation capacity alone. “Cleaner power. Stronger grids. More opportunities,” he said, calling it a “big push towards 900 GW non-fossil capacity by 2035.” The government said the scheme is expected to generate employment in manufacturing, construction, battery storage and grid operations across the states and union territories where projects are built.
Background: India’s Green Energy Corridor programme
India launched its first Green Energy Corridor scheme over a decade ago to build transmission infrastructure for evacuating renewable power from resource-rich states to demand centres, a response to grid bottlenecks that left wind and solar capacity underused in some regions. Phase-II expanded the programme’s geographic scope and transmission capacity in subsequent years. Phase-III, approved September 30, 2026, is the first phase to dedicate a specific allocation, 50,000 crore rupees, to grid-scale battery storage rather than transmission lines alone, reflecting the shift in India’s renewable buildout from a generation-capacity problem to a grid-flexibility problem. The scheme sits within India’s wider commitment to reach 500 GW of non-fossil capacity by 2030 and 900 GW by 2035, a target the government has repeated across recent cabinet announcements on transmission and storage funding.
