Power Grid Corporation of India Ltd (POWERGRID) said in a BSE filing dated August 4, 2026, that the POWERGRID Rajasthan transmission project for evacuating power from the state's 20 GW renewable energy zone has been completely commissioned. The project, formally named “Transmission System for evacuation of Power from REZ in Rajasthan (20 GW) under Phase-III Part-H”, achieved complete commissioning with effect from July 4, 2026.

The state-owned transmission company informed BSE and the National Stock Exchange under Regulation 30 of the SEBI Listing Obligations and Disclosure Requirements Regulations. POWERGRID trades under the NSE symbol POWERGRID and BSE scrip code 532898.

The disclosure confirms completion of the specified transmission system intended to support evacuation of electricity from Rajasthan's renewable energy zone. The filing did not disclose the project's investment amount, transmission capacity beyond the stated REZ reference, or expected financial contribution.

Commercial operation notification received

POWERGRID said the Notification for Commercial Operation, or DOCO, was dated July 9, 2026. The company received the notification by email on August 3, 2026, before informing the stock exchanges the following day.

The filing outlined the sequence of events connected with the project's commissioning:

  • The transmission project was completely commissioned effective July 4, 2026.
  • The commercial operation notification was issued on July 9, 2026.
  • POWERGRID received the notification by email on August 3, 2026.
  • The company disclosed the development to BSE and NSE on August 4, 2026.

The announcement provides investors with a confirmed operational milestone for the Phase-III Part-H transmission system. It does not provide details on project costs, regulated returns, tariff impact or the timeline for associated renewable generation. Any assessment of financial implications would therefore require further disclosures from the company.

Project entity underwent amalgamation

The project was originally entrusted to POWERGRID Beawar Dausa Transmission Limited, which was then a wholly owned subsidiary of Power Grid Corporation of India. According to the filing, that entity was amalgamated with POWERGRID Vataman Transmission Limited with effect from March 1, 2026.

The amalgamation followed an order dated January 27, 2026, issued by the Ministry of Corporate Affairs. POWERGRID's latest exchange disclosure links the completed Rajasthan transmission project with the successor entity following this corporate restructuring. The filing was signed by Anjana Luthra, Company Secretary and Compliance Officer, and submitted for the information and records of both stock exchanges.
