Power Grid Corporation of India commissions Karnataka REZ project

Power Grid Corporation of India Limited commissioned its Karnataka Renewable Energy Zone transmission project with effect from 23 October 2026 after receiving the Declaration of Commercial Operation, or DOCO, moving the project from construction into commercial operation. The development concerns renewable-power evacuation infrastructure covering Koppal-II and Gadag-II in Karnataka.

What has Power Grid Corporation of India commissioned in Karnataka?

Power Grid Corporation of India Limited, referred to as POWERGRID, has declared commercial operation of the transmission scheme for integration of Renewable Energy Zone Phase-II in Koppal-II Phase-A and Phase-B and Gadag-II Phase-A in Karnataka. The company said the project was commissioned effective 23 October 2026 after it received the DOCO.

The project is designed to support the integration of renewable energy into the transmission network. Its stated scope covers the Koppal-II and Gadag-II renewable energy zones in Karnataka, though the available disclosure does not specify the project's transmission capacity, route length, capital cost, or individual substations.

Commercial operation is an important milestone for a transmission project because it marks the shift from construction to operational status. POWERGRID's announcement described the project as having moved into commercial operation rather than remaining under construction.

How did the Karnataka project reach commercial operation?

POWERGRID said the commercial-operation milestone followed receipt of the DOCO, with the effective date set as 23 October 2026. The company also referred to the amalgamation of PKGTL with Khavda II-C Transmission in its disclosure concerning the project.

The information supplied does not provide the date on which construction began, the date of physical completion, or the regulatory process preceding the DOCO. It also does not quantify the financial impact of the asset's commissioning. These details therefore cannot be assessed from the stated announcement.

The Karnataka commissioning came during a series of POWERGRID disclosures relating to renewable-energy transmission projects and tariff-based competitive bidding, or TBCB. The company disclosed the commissioning of a Rajasthan renewable-energy evacuation project on 11 October 2026 and a solar energy zone transmission scheme in Bidar, Karnataka, on 8 October 2026.

What other renewable transmission activity has POWERGRID disclosed?

POWERGRID has reported multiple renewable-energy-related project and acquisition developments in October 2026. It disclosed acquisitions of Jam Khambhaliya REZ Transmission Limited, Lakadia C Power Transmission Ltd., and Lakadia II Power Transmission Limited under the TBCB route on 12 October 2026.

On 16 October 2026, POWERGRID said it had been declared the successful bidder under TBCB. The source material does not identify the specific project in that brief item. Together, these disclosures show continuing activity in project execution and in the acquisition of transmission special-purpose vehicles, but they do not establish revenue or earnings contribution from the Karnataka asset.

India's power system has been expanding transmission infrastructure to connect renewable-energy zones with demand centres. The source also notes that POWERGRID has been assigned as an implementing agency for a Rajasthan transmission-strengthening scheme for renewable-power evacuation and that projects worth Rs 900 crore were dedicated on 16 February 2024, including a Rajasthan Phase-II Part-A scheme.

How does the commissioning relate to POWERGRID's financial disclosures?

The commissioning was disclosed alongside a period of board-level financial and corporate actions at POWERGRID. At its 1 November 2026 board meeting, the company approved unaudited standalone results described in the source as Q3 FY26 and H1 FY26, and declared an interim dividend of Rs 3 per share.

According to the information provided, total income was Rs 11,899.96 crore for the quarter and Rs 23,270.00 crore for the half year. Net profit was reported at Rs 3,819.08 crore for the quarter and Rs 7,242.44 crore for the half year, compared with half-year net profit of Rs 6,474.49 crore in the preceding comparison period.

The board set 6 November 2026 as the record date for the interim dividend and 30 November 2026 as its payment date. It also approved the sale of POWERGRID's entire stake in Central Transmission Utility of India Ltd to Grid Controller of India for an initial Rs 73.46 crore, subject to a true-up after post-valuation adjustments.

What does the project mean for investors and power-sector operations?

For POWERGRID, the Karnataka asset's commercial status adds an operational renewable-energy transmission project to its portfolio. The disclosure itself does not state the tariff, annual revenue, regulated return, project cost, or expected earnings from the asset, so no direct financial contribution can be calculated from the available information.

For the wider sector, the project forms part of the infrastructure required to evacuate electricity from renewable-energy zones. Its operation is relevant to developers and grid planners because generation capacity requires transmission connectivity before it can be delivered through the network. The announcement, however, does not provide data on generator connectivity, power flows, or customer impact.

The company is also pursuing a wider restructuring of project subsidiaries. Its board approved a revised plan to merge 28 wholly owned subsidiaries into two group entities, replacing an earlier plan involving 11 subsidiaries. The proposal remains subject to regulatory approvals, and POWERGRID has said further developments will be communicated.

Conclusion

POWERGRID's 23 October 2026 commercial-operation declaration confirms that the Koppal-II and Gadag-II renewable-energy transmission scheme in Karnataka has progressed beyond construction. The milestone sits alongside other October disclosures involving renewable transmission commissioning, TBCB activity, and the acquisition of transmission entities.

Investors can watch for further details on the Karnataka project's tariff, cost, capacity, and financial contribution, none of which were included in the supplied disclosure. Nearer-term scheduled dates include the 6 November 2026 dividend record date and 30 November 2026 interim-dividend payment date, while the subsidiary merger plan awaits regulatory approvals.
