POWERGRID Declared Successful Bidder for Major Southern Region Inter-State Transmission Project

State-run power transmission behemoth Power Grid Corporation of India Limited (NSE: POWERGRID | BSE: 532898) announced on Friday, July 10, 2026, that it has secured a major Inter-State Transmission System (ISTS) contract under the Tariff-Based Competitive Bidding (TBCB) framework.

The enterprise received the formal Letter of Intent (LoI) on July 10, 2026, solidifying its selection for the project titled "Transmission System for integration of Krishnagiri REZ Phase-I."

The corporate announcement was filed with both the National Stock Exchange of India Limited (NSE) and the BSE Limited under Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.

Project Scope: Empowering Renewable Energy Integration

The mega-infrastructure project is slated to be developed on a Build, Own, Operate, and Transfer (BOOT) basis. This system is designed to integrate renewable energy zones (REZ), facilitating clean energy transmission across multiple southern states.

The project features extensive engineering and structural developments:

• Substation Infrastructure: The establishment of two brand-new 765/400kV Substations located in the state of Andhra Pradesh.

• Grid Network: The construction of massive 765kV and 400kV transmission lines that will traverse through three key southern states: Andhra Pradesh, Telangana, and Karnataka.

• Bay Extensions: The development of associated bays to seamlessly link the new transmission lines to the existing regional power grids.

Market Implications and Growth Strategy

This win highlights POWERGRID's dominance in India's competitive power transmission landscape. The central government's ongoing push to build green energy corridors relies heavily on state-of-the-art ISTS systems to move clean energy generated in resource-rich areas (like southern solar and wind pockets) to high-demand industrial centers.

As of July 2026, POWERGRID operates a vast network, maintaining approximately 85% of India’s inter-regional transmission capacity. Analysts view this newly won southern corridor project as another strong contributor to the utility major’s long-term capitalization and revenue visibility, ensuring a steady stream of regulated returns under the BOOT model.
