What was filed
Power Grid Corporation of India told the exchanges that its project, "Transmission system for evacuation of power from REZ in Rajasthan (20 GW) under phase-III Part-C1," has been fully commissioned. Per the filing, the project went commercial with effect from 22 September 2026, and the company received the Notification for Commercial Operation (DOCO), dated 7 October 2026, by email on 11 October 2026.
The entity that built it
The project was entrusted to POWERGRID Ramgarh II Transmission Limited, described in the filing as then a wholly owned subsidiary of Power Grid. That subsidiary has since been amalgamated with POWERGRID Vataman Transmission Limited with effect from 1 March 2026, under an order dated 27 January 2026 of the Ministry of Corporate Affairs. The commissioned asset therefore now sits within the amalgamated entity.
Why it matters to a holder
A Renewable Energy Zone (REZ) evacuation system is the inter-state transmission infrastructure that moves power generated in renewable-rich areas onto the grid. For a transmission utility, commissioning is the point at which an asset becomes commercially operational and begins its revenue-earning life. The filing records that milestone for this project but does not disclose its cost, capacity utilisation terms, or revenue.
