Key Details
Green Energy Corridor Phase III (GEC-III) adds storage to the transmission infrastructure needed for the next wave of renewable-power projects.
Measure | Cabinet Approval |
|---|---|
Renewable capacity supported | Transmission to evacuate up to 135 GW across states and Union Territories |
Battery energy storage | 50 GWh, located at generation sites or elsewhere where it can support grid flexibility |
Total project outlay | ₹1,86,405 crore, including ₹54,082 crore in central financial support |
Target completion | FY 2032–33 |
Delivery | Competitive bidding for new transmission projects; cost-plus execution for upgrades to existing networks |
Transmission and Storage Address Different Grid Constraints
Renewable generation needs lines to carry electricity from projects into the grid. Intra-state transmission serves this movement within a state or Union Territory; GEC-III is intended to provide capacity for up to 135 GW of renewable power.
The 50 GWh battery-storage component addresses a different problem. Batteries can absorb electricity when generation is available and supply it later, helping manage congestion, peak-hour curtailment and demand outside solar hours. The approval provides for storage at renewable-generation sites or other locations important to grid flexibility.
New Lines and Existing Networks Will Be Delivered Differently
State Transmission Utilities will oversee implementation. New transmission projects will be awarded through tariff-based competitive bidding, with selected providers building, owning, operating and maintaining the assets. Upgrades and strengthening of existing networks will follow a cost-plus route.
The Centre’s financial support is intended to offset intra-state transmission charges and limit their effect on electricity costs. That is the scheme’s stated aim; the cost ultimately faced by consumers will depend on project delivery and how the support is applied.
Policy Relevance
The approval treats grid capacity and flexibility as part of renewable-energy expansion, rather than assuming new generation can be absorbed by existing networks. For states, the immediate planning task is to align transmission projects and storage locations with where renewable capacity is actually being built.
The outcome to watch is not only how many lines and batteries are commissioned, but whether they reduce congestion and curtailment and make renewable power available when it is needed. The FY 2032–33 timetable makes coordination between developers, transmission utilities and storage providers consequential.
Relevant Question for Policy Stakeholders: How will states sequence transmission and battery projects so that grid capacity is ready when new renewable generation comes online?
