New Delhi: Power Grid Corporation of India Limited (Power Grid) has been declared the successful bidder for three significant Inter-State Transmission System (ISTS) projects under the Tariff Based Competitive Bidding (TBCB) mechanism. These projects will be developed under the Build, Own, Operate, and Transfer (BOOT) model, reinforcing India’s power transmission network, particularly in supporting renewable energy evacuation and grid integration.
The company received the Letter of Intent (LoI) for these projects on March 3, 2025, as per a regulatory filing made to the National Stock Exchange (NSE) and Bombay Stock Exchange (BSE). The projects, which involve major infrastructure upgrades in Rajasthan, Gujarat, Andhra Pradesh, and Karnataka, aim to enhance the transmission capacity to integrate renewable energy sources into the national grid.
The key details of the three projects are as follows:
- Transmission System for Evacuation of Power from Rajasthan REZ Ph-V (Part-1: 4 GW) – This project involves augmenting the transformation capacity at the under-construction Sirohi substation in Rajasthan, along with the construction of 765kV double circuit (D/C) transmission lines across Rajasthan and Madhya Pradesh.
- Augmentation of Transformation Capacity at Banaskantha (Raghanesda) PS (GIS), Gujarat – The second project focuses on increasing transformation capacity at the existing Banaskantha PS in Gujarat, with additional works at the power station.
- Transmission System for Integration of Kurnool-IV REZ – Phase-I (4.5 GW) – This project involves establishing a new 765/400/220kV pooling substation in Kurnool, Andhra Pradesh, along with the augmentation of transformation capacity at the C’peta substation. It also includes the construction of 765kV and 400kV D/C transmission lines spanning Andhra Pradesh and Karnataka.
These initiatives are expected to significantly enhance the capacity and reliability of India’s transmission network, particularly in handling renewable energy generated in the western and southern regions, which is crucial for achieving the country’s green energy goals.
