Mumbai: Power and automation technology company ABB India Ltd has won a Rs4,350 crore order from national electricity grid operator Power Grid Corp. of India Ltd to build a 1,830km transmission link, the company said on Tuesday.
The Raigarh-Pugalur 800 kilovolt (kV) ultra high-voltage direct current (UHVDC) system will connect Raigarh in Chhattisgarh to Pugalur in Tamil Nadu, ABB said in a statement.
The project will be among the longest links in the world and with a capacity of 6,000 megawatts (MW), and it will meet the electricity needs of over 80 million people in the country, the statement added. “The two-way link will integrate thermal and wind energy for transmission of power to high consumption centres located thousands of kilometres away, supporting electricity demands in the south, when wind strength is low, and transmitting clean energy to the north, when there is excess wind power.”
The total project value is worth more than Rs5,700 crore and the balance will be executed by ABB’s consortium partner Bharat Heavy Electricals Ltd (BHEL).
The order was booked in the fourth quarter of 2016 and the project is expected to be completed in 2019, ABB said.
The turnkey project encompasses design, engineering, supply, installation and commissioning and major equipment supplies include the complete UHVDC stations, including transformers, converter valves, cooling systems, as well as control and protection technology. UHVDC transmission is an advanced version of HVDC, a technology pioneered by Swiss group ABB.
