Raigarh – Pugalur UHVDC Link

Enough electricity to serve around 80 million people

ABB was selected by Power Grid Corporation of India Ltd. to deliver the ±800 kV, 6,000 MW Raigarh - Pugalur UHVDC link, which will transmit power from central India to consumers in the south, a distance of 1,830 km.

ABB and Bharat Heavy Electricals Ltd. (BHEL) have turnkey responsibility for execution, including system engineering, design, supply and installation of two UHVDC converter stations.

This link is ABB’s sixth HVDC project in India and the second UHVDC project.

At full capacity, the Raigarh - Pugalur UHVDC link will be able to supply enough electricity to serve around 80 million people, based on the national average per capita consumption. Ultrahigh voltage minimizes transmission losses, reducing CO2 emissions, and improves grid efficiency.
