Indian Power news: TANTRANSCO rate-contract tender targets 14 high-capacity transmission transformers
Indian Power news reports a significant procurement initiative by Tamil Nadu Transmission Corporation Limited involving the supply and commissioning of fourteen 160 MVA, 230/110 kV auto transformers. Issued under specification T-2373, the tender establishes a rate-contract framework allowing the utility to procure high-capacity transformers in phases as grid expansion projects progress.
The tender document became available on 6 March 2026 through the Tamil Nadu e-tender portal. Bidders must submit techno-commercial offers by 7 April 2026, while the technical bid opening is scheduled for 8 April 2026. According to Indian Power news, the procurement process is restricted to domestic bidders, limiting participation to Indian transformer manufacturers.
The contract scope includes design, manufacturing, transportation, erection and commissioning of the transformers. These 160 MVA units act as critical voltage interface equipment that transfer power between 230 kV transmission corridors and the 110 kV network supplying distribution substations.
The rate-contract structure enables TANTRANSCO to standardise transformer specifications across multiple substations while maintaining procurement flexibility. Utilities increasingly adopt such procurement methods when several substations require identical equipment specifications within a short infrastructure rollout cycle.
For readers following Indian Power news, the programme signals upcoming upgrades in the state’s transmission network. High-capacity transformers remain essential components supporting Smart grid reliability and load balancing across regional power corridors.
