NTPC Green Energy Limited, a wholly owned subsidiary of NTPC, has invited bids for the development of a 132 kV GIS-based substation at the Pudimadaka Green Hydrogen Hub in Andhra Pradesh. Issued under IFB No. NGEL-CS-5861-GH2HUB-PSE-PUD-1-001, the tender calls for experienced contractors capable of delivering end-to-end substation infrastructure. The scope spans design, detailed engineering, manufacturing, supply, installation, testing and commissioning, signalling NTPC Green’s push to establish robust electrical systems for its hydrogen initiatives.

The project centres on a 132/33 kV substation equipped with 80 MVA transformers and 132 kV GIS. It further includes medium and low-voltage switchgear, comprehensive protection systems, SCADA and advanced automation. In addition to core equipment, the tender covers associated grid infrastructure such as cable networks, earthing systems, surge and lightning protection and AC/DC power supplies. The selected contractor will be responsible for seamless integration of the substation with APTRANSCO’s network to ensure stable, reliable power for hydrogen production operations.

Stringent requirements and strategic importance

Bidders must meet strict technical and financial criteria, demonstrating experience in executing large-scale substation projects and EPC assignments. The structure of the tender places responsibility for the entire project lifecycle on the contractor, from conceptual engineering through supply and installation to final commissioning. This approach aims to ensure dependable and consistent power delivery for NTPC’s green hydrogen plans at Pudimadaka.

The substation forms a critical component of the Pudimadaka Green Hydrogen Hub, a flagship undertaking aligned with India’s broader clean-energy transition. As NTPC accelerates its hydrogen ambitions, secure and uninterrupted power becomes essential for electrolysers and supporting systems. A dedicated GIS-based substation will help enhance grid stability, support high-capacity renewable integration and strengthen the reliability of energy supply for advanced hydrogen production technologies.

Full bidding documents, including technical specifications and submission procedures, are available on the NTPC and NIC e-procurement portals. Interested bidders are advised to closely monitor deadlines for submission, bid opening and compliance requirements. The project represents a significant opportunity for qualified EPC contractors to participate in one of India’s most prominent emerging hydrogen infrastructure developments.
