Powergrid Corporation of India (PGCIL) has awarded a contract to Alstom T&D India and Alstom Grid UK to supply and refurbish high voltage direct current (HVDC) converter transformers in the Indian state of Maharashtra.
The HVDC converter transformers will strengthen the 1,000MW HVDC station at Bhadrawati in Maharashtra, which interconnects and moves surplus power from West India to South India.
Valued at €22.75m (INR1.82bn), the turnkey contract involves designing, engineering, manufacturing, refurbishing, and the erection and commissioning of 234MVA, 400kV HVDC converter transformers.
Completed in 1997, the Bhadrawati HVDC station already features Alstom equipment. With the new contract, Alstom will replace the old transformers with new HVDC converter transformers and extend the life of the existing substation.
This replacement of the transformers will strengthen the transmission link with the southern region, ensuring reliable power supply between the Western and the Southern grid.
Alstom T&D India managing director Rathin Basu said the company’s future-ready, high quality HVDC products and solutions are pivotal to bulk power transport in India.
"With our world class transformer facilities across Vadodara, Gujarat and Naini, Uttar Pradesh in India, Alstom offers the widest range of fully localised alternating current and HVDC transformer solutions up to 800 kV," Basu said.
Alstom will manufacture the HVDC converter transformers at its facilities in Vadodara, India and in Stafford, the UK.
In August 2013, PGCIL announced investment approval of INR1.36bn for the installation of a transformer and the procurement of a spare converter transformer at the Bhadrawati HVDC back to back station.
