The Union Cabinet has approved the Green Energy Corridor Phase-III to support 135 GW of renewable energy and 50 GWh of battery storage. With a total investment of Rs 1.86 lakh crore, the project aims to fix grid connectivity bottlenecks, providing long-term stability and visibility for power sector companies.
The Union Cabinet has officially approved the Green Energy Corridor Phase-III (GEC-III) project, committing a total outlay of Rs 1,86,405 crore. This large-scale infrastructure initiative is designed to strengthen the nation's transmission network to handle 135 GW of renewable energy, supported by 50 GWh of Battery Energy Storage Systems (BESS). The government has allocated Rs 54,082 crore as Central Financial Assistance to help keep overall power costs affordable for consumers.
The core objective of this phase is to fix the persistent issue of grid congestion and curtailment, which occurs when renewable power generation exceeds the grid’s current capacity to transport it. By upgrading transmission lines and adding storage, the government aims to ensure that clean energy produced at renewable sites can be effectively delivered to the grid and used by households and industries. The completion of these projects is targeted by the fiscal year 2032-33.
For the power sector, this investment changes the outlook for both equipment manufacturers and energy project developers. The government plans to use two main methods to award projects: Tariff Based Competitive Bidding (TBCB) for new greenfield developments and a Cost Plus Basis for upgrading existing brownfield infrastructure. This creates a steady pipeline of work for companies involved in building transmission lines, substations, and battery storage solutions.
While this approval provides a strong signal for growth, investors may keep a close eye on execution risks. The success of the corridor relies heavily on the efficiency of State Transmission Utilities (STUs), as they are primarily responsible for implementing the projects at the state level. Any delays in land acquisition, regulatory approvals, or the construction of sub-stations at the state level could push back project timelines.
Additionally, the scale of this project requires significant domestic manufacturing capacity, particularly for advanced transmission equipment and battery systems. The pace at which the industry can scale up this manufacturing will be a critical factor to watch. Market participants will likely track upcoming tender announcements and the speed of project execution as key indicators of how quickly this capital expenditure translates into actual revenue for infrastructure and power equipment companies.
