The second HVDC Light project in Australia.
The Murraylink 220 MW interconnector between the Riverland in South Australia and Sunraysia in Victoria is a 180 kilometer underground high-voltage power link. Murraylink is believed to be the world’s longest underground transmission system.
ABB has provided a complete HVDC Light transmission system, made up of high-tech extruded cables buried in the ground, with a HVDC Light converter station at each end of the link. The order was placed by Murraylink Transmission Company Pty. (TransÉnergie Australia), a subsidiary of TransÉnergie, the transmission division of Hydro-Québec, Canada. It is now owned by Energy Infrastructure Investments consortium and operated by the APA Group.

Murraylink benefits both South Australia and Victoria by enabling electricity trading in Australia’s deregulating power market.
From its near tri-state border site, it can deliver power from South Australia, Victoria, NSW and the Snowy River generation in either South Australia or Victoria. Murraylink has used existing corridors and required no private easements, nor use of private land.
