The Tamil Nadu Transmission Corporation Limited (TANTRANSCO) has awarded three contracts to Alstom T&D India to help strengthen grid infrastructure in the state.
Under the contract, valued at €30m (INR2, 400m), Alstom will supply three air-insulated substations to the state of Tamil Nadu to establish a reliable grid.
The scope of the contract includes establishing a 400 / 230 / 100kV air-insulated substation at Rasipalayam, connecting Tamil Nadu's transmission network to the national grid, and two 230 / 110kV air-insulated substations each in Vyasarpadi and the Omega industrial estate, both near Chennai.
Alstom will supply 62 air-insulated bays, two power transformers, eight auto-transformers and other equipment, from its manufacturing facilities across the country.
Alstom T&D India managing director Rathin Basu said: "Alstom is proud to play a key role in the transmission network of the state of Tamil Nadu.
"With its advanced transmission technologies and strongly localised manufacturing footprint, Alstom T&D India is ready to support the state government's plans to strengthen the transmission network backbone, and to distribute quality power efficiently to the consumers."
Energy consumption in Tamil Nadu has grown at 6% a year between 2004 and 2011, and is estimated to grow another 7% during the 12th Five Year Plan 2012-2017.
