POWERGRID Issues 400 kV GIS Substation Tender for Tuticorin Green Hydrogen Hub

In a strategic move to fortify Tamil Nadu’s burgeoning green hydrogen corridor, Power Grid Corporation of India Limited (POWERGRID) has invited online bids for the development of a critical 400 kV Gas Insulated Substation (GIS) in the Tuticorin region. This package, designated as “400kV GIS Substation Package SS 104T,” represents a foundational component of the transmission infrastructure required to support India’s National Green Hydrogen Mission. The project is specifically designed to facilitate power evacuation for large-scale Green Hydrogen and Green Ammonia investments, aligning with the Ministry of Power’s September 12, 2024, notification regarding Inter-State Transmission System (ISTS) development in the area.

Technical Scale and Competitive Context

This tender is not merely an isolated works contract; it is a critical sub-component of a massive infrastructure build-out. The broader project involves the establishment of the 3×1500 MVA, 765/400 kV Tuticorin (GH) Substation, highlighting the immense scale of the power evacuation requirements.

By floating this tender before submitting its own proposal to the Bid Process Coordinator (BPC), POWERGRID is employing a preemptive procurement strategy. This tactical move is designed to de-risk its bid for the overall Transmission Service Provider (TSP) role—competing against major private sector players like Adani Energy Solutions and Sterlite Power—by locking in technical partners and equipment schedules. This ensures the utility can meet the aggressive 30-month Scheduled COD (Commissioning Date) mandated by the project framework once the TSP license is awarded.

Key Tender Specifications and Framework

The technical and procedural parameters for this procurement include:

• Framework: The tender is issued under the Tariff-Based Competitive Bidding (TBCB) framework.
• Contract Category: This is classified as an open works contract within the power and energy sector.
• Infrastructure Type: The project involves a high-specification 400 kV Gas Insulated Substation (GIS).
• Location: Tuticorin, Tamil Nadu.
• BPC Role: POWERGRID is conducting this package-level bidding prior to the final TSP selection being coordinated by the BPC.

Financial and Participation Requirements

The financial criteria for interested parties emphasize streamlined participation for qualified entities:

• Tender Fee: POWERGRID has specified that no tender fee is prescribed for accessing the documents.
• Earnest Money Deposit (EMD): In an effort to encourage broad participation, no EMD is required at this stage of the bidding process.
• Performance Bank Guarantee (PBG): Detailed requirements for the PBG are available in the commercial documents and follow standard POWERGRID corporate guidelines.
• Eligibility: The bidding is open to qualified domestic and international bidders, ensuring the project benefits from global expertise in GIS technology.

Bidding Schedule and Platform Details

The timeline for the June 2026 bidding cycle is focused and urgent, reflecting the strategic priority of the project:

Project Management and Broader ISTS Framework

The procurement process is managed through POWERGRID’s corporate office in Gurugram, Haryana, under the supervision of Yogesh Kushwaha, Manager (CS).

While POWERGRID is managing the procurement for this specific substation package, REC Power Development and Consultancy Limited (RECPDCL) serves as the overall Bid Process Coordinator (BPC) for the broader Inter-State Transmission System (ISTS) project in Tuticorin. RECPDCL is responsible for selecting the final Transmission Service Provider who will own and operate the project on a Build, Own, Operate, and Transfer (BOOT) basis for a period of 35 years. The successful execution of this substation package is vital to meeting the long-term sustainability goals of the Tuticorin region as it transforms into a global destination for clean energy investments.
