state-run power equipment maker Bharat Heavy Electricals Ltd (Bhel), in association with ABB, has been awarded a project worth Rs.1,360 crore from Power Grid Corp.
Bhel’s scope of work is valued at Rs.1,360 crore for setting up a 800 kilovolt (kV), 6,000 megawatt (MW) high-voltage, direct current (HVDC) link between western region grid (Raigarh, Chhattisgarh) and southern region grid (Pugalur, Tamil Nadu).
This is the second ultrahigh-voltage, direct current (UHVDC) transmission project contract for Bhel, the company said on Tuesday.
It is presently executing the northeast Agra 800kV, 6,000MW, multi terminal HVDC link, jointly with ABB.
This project will bring relief to power deficit southern grid. The HVDC link is expected to be established by 2019, it added.
For this project, among other equipment and systems, Bhel will significantly contribute by supplying converter transformers, shunt reactors, filter bank capacitors and instrument transformers from its Bhopal plant and thyristor valves from its electronics division, Bengaluru.
These valves will be used to convert AC power generated at the independent power producers (IPPs) at Raigarh into DC power for transmitting it over a HVDC transmission line of over 1,800km and then converting it back into AC at the Pugalur end for interconnection with the southern grid, it said.
Bhel has been associated with HVDC projects in India since their inception. The company has been involved in successful execution of several HVDC links in the past like Rihand-Dadri, Chandrapur-Padghe and Ballia-Bhiwadi links and has established state-of-the-art manufacturing facilities for HVDC products up to 800kV.
