CHANGE IN LAW CLAUSE REVISED TO ALLOW TARIFF IMPACT POST-BID DEADLINE
8The latest amendment to this 400 kV intra-state substation package introduces a critical tweak: only post-bid changes in law that affect TSP’s cost or savings will now qualify for compensation under TSA. This risk-sharing clause could influence bid aggressiveness and lender appetite.
8Two sets of 400 kV LILOs are planned: one terminating at the Hampapura substation and another extending connectivity to a new 765/400 kV node under ISTS. This setup boosts redundancy and links intra-state flows with central transmission systems.
8The tender assures that deemed license powers under Section 164 will be granted within 45 days of application, allowing the TSP to access statutory RoW and streamline line execution without prolonged clearances.
DUAL ICT AUGMENTATION DRIVES GIS SUBSTATION EXPANSION ACROSS TWO MAJOR LOAD CENTERS
8This 400kV GIS package covers 1x500 MVA ICT additions at key substations in Delhi and Uttar Pradesh, targeting transformation upgrades in dense urban networks. The scope includes high-voltage switchgear, control, and relay panels integrated under compressed timelines.
8A key element of this GIS tender is a dedicated 400 kV sectionalization bay to interconnect split 400 kV sections at a critical 765/400 kV station. Designed to mitigate contingency risks, this bay must be delivered within 14 months—faster than the 20-month window for other nodes. The 500 MVA ICTs under this package will use oil-to-SF6 bushings, requiring hybrid insulation interfaces. The substation extensions will also integrate associated protection, control, relay panels, bus ducts, and interconnection works.
8With its tight execution timelines and emphasis on hybrid insulation, this tender exemplifies the growing complexity of transmission equipment tenders India. The inclusion of sectionalization bays and SF6 interfaces underscores evolving engineering benchmarks across transmission equipment tenders India, particularly in high-load metro zones. The project will likely attract OEM-aligned bidders familiar with fast-track transmission equipment tenders India under urban GIS deployment norms.
LEGACY INFRA FIRMS FACE OFF IN FULL?SCOPE BOP TENDER FOR 800 MW UNIT
