Power Grid Corporation of India Ltd has approved a ₹856.94 crore investment to upgrade critical transmission infrastructure in Tamil Nadu through a reconductoring project. The company’s Committee of Directors on Investment on Projects granted approval during its meeting on August 05, 2026, marking a significant capital allocation aimed at enhancing grid capacity and reliability in the southern region.

The approved initiative involves the reconductoring of the Tirunelveli – Udumalpet and Pugalur - Madurai 400kV double-circuit lines using High-Temperature Low-Sag (HTLS) conductors. This technical upgrade is designed to increase the thermal rating of existing towers without requiring new right-of-way acquisitions, thereby optimizing asset utilization. The expenditure will be booked under Additional Capital Expenditure, reflecting the company’s strategy to expand network capabilities through targeted infrastructure enhancements rather than greenfield expansion alone.

Project Details and Timeline

The project is structured for rapid execution, with a strict commissioning deadline set within 24 months from the date of project allocation. This timeline places the expected completion date by February 11, 2028. The use of HTLS conductors is a strategic choice, allowing for higher current-carrying capacity on existing infrastructure, which is crucial for managing increasing power demand in the region while minimizing environmental and social impacts associated with new tower construction.

Regulatory Disclosure

The investment approval was disclosed to the National Stock Exchange of India Limited and BSE Limited in compliance with Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015. The disclosure was issued by Anjana Luthra, Company Secretary & Compliance Officer, underscoring the formal governance process behind the capital allocation decision.

What the Numbers Show

The ₹856.94 crore outlay represents a focused capital deployment on brownfield upgrades rather than new line construction. By selecting HTLS technology for these specific 400kV corridors, Power Grid is likely addressing thermal bottlenecks that constrain power transfer from generation hubs in Tamil Nadu to load centers. The tight 24-month execution window suggests a prioritized schedule, potentially linked to seasonal power demand cycles or upcoming generation capacity additions in the region that require immediate evacuation support.

The Board of Directors of Power Grid Corporation of India approved an amended 'Code of Practices & Procedures for Fair Disclosure of Unpublished Price Sensitive Information and Conduct for Regulating, Monitoring & Reporting of Trading in Securities' during a meeting held on August 5, 2026. This regulatory update ensures that the disclosure of Unpublished Price Sensitive Information (UPSI) adheres to current market standards, directly impacting how insider trading is monitored and reported for the utility giant.

The approval was formalized in a letter dated August 5, 2026, addressed to the General Manager (Listing) at both the National Stock Exchange of India Limited and BSE Limited. Anjana Luthra, Company Secretary & Compliance Officer, signed the communication, confirming that the Board had reviewed and adopted the changes to the existing Code.

Regulatory Framework Update

The amended Code specifically targets the fair disclosure of UPSI and establishes conduct guidelines for regulating, monitoring, and reporting trading activities in Power Grid Corporation of India Limited's securities. By updating these procedures, the company aligns its internal controls with SEBI’s Insider Trading Regulations, ensuring that any material non-public information is handled with strict confidentiality until public dissemination.

Implementation and Accessibility

Following the Board's approval, the updated Code has been made available on the company’s official website at www.powergrid.in . This transparency measure allows shareholders, investors, and regulators to review the specific procedures governing the handling of price-sensitive information. The move reinforces Power Grid Corporation of India Limited's commitment to corporate governance and market integrity.

No financial metrics or operational data were disclosed in this filing, as the focus remains solely on compliance and procedural governance. The adoption of this amended Code serves as a preventive control mechanism, reducing the risk of inadvertent leakage of UPSI and ensuring that all trading by designated persons is properly monitored and reported.
