Bharat Heavy Electricals Limited (BHEL) in collaboration with ABB has won a INR13.6bn ($200M) order from the Power Grid Corporation of India to deliver the ultra high voltage direct current (UHVDC) transmission project in India.
Under the contract, BHEL will be responsible for setting up a + 800kV, 6,000MW HVDC link between the Western Region Grid (Raigarh, Chattisgarh) and the Southern Region Grid (Pugalur, Tamil Nadu).
For the project, BHEL will supply converter transformers, shunt reactors, filter bank capacitors and instrument transformers from its Bhopal plant and thyristor valves from its electronics division, Bengaluru.
The valves will be used to convert the AC (alternating current) power generated at the IPPs (independent power producers) at Raigarh into DC (direct current) power for transmission over a HVDC transmission line of more than 1,800km. The DC power will be then converted back into AC at the Pugalur end for interconnection with the Southern Grid.
The HVDC link is expected to be complete by 2019.
The link represents the second UHVDC transmission project contract awarded to BHEL. The company is currently executing the North-East Agra + 800kV, 6,000MW Multi Terminal HVDC link jointly with ABB.
