The Power Grid Corporation of India Limited (PGCIL) has announced a new tender for a major substation development package in Rajasthan, aimed at enhancing grid connectivity for large-scale renewable energy projects while integrating advanced battery energy storage systems (BESS).
The tender, designated Substation Package SS-07, includes the creation of one 220 kV line bay at the 765/400/220 kV Barmer-I pooling substation. This infrastructure will support the interconnection of Anboto Solar Private Limited’s renewable projects, totaling 250 MW, with an additional 50 MW capacity.
Crucially, the project also covers the development of a 220 kV line bay at the 400/220 kV Fatehgarh-III pooling station (Section 1), specifically designed to integrate the battery energy storage system of JSW Renew Energy Five Ltd. The inclusion of BESS underscores India’s commitment to grid stability and efficient renewable energy utilization, enabling the storage and dispatch of clean power in alignment with demand fluctuations.
The scope of work encompasses detailed engineering, design, supply, and construction activities for the establishment of these new line bays. The tender was officially released on 10 January 2026, with both soft-copy and hard-copy bid submissions beginning the same day. Soft-copy bids will be accepted until 31 January 2026, 11:00 AM, while hard-copy submissions close on 2 February 2026, 11:00 AM. A pre-bid meeting is scheduled for 20 January 2026, 11:00 AM to address technical and commercial queries from prospective bidders.
The tender requires a non-refundable document fee of ₹25,000, and an Earnest Money Deposit (EMD) of ₹15,90,000. While the tender notice lists the project value as zero, performance bank guarantees will be mandated in line with standard contractual requirements. Detailed Pre-Qualification Requirements are outlined within the tender documents.
The work locations span Barmer and Jaisalmer districts, key regions for India’s renewable energy expansion. The project is being managed by Vijay Prakash Jarwal, DGM (C&M), at the Rajasthan Projects Office, REIL House, Mansarovar, Jaipur.
Once operational, the upgraded substations and integrated battery energy storage systems are expected to enhance transmission capacity, stabilize the grid, and improve the efficiency of renewable energy evacuation, supporting India’s broader transition toward cleaner, reliable power generation.
