Murraylink was commissioned in 2002 and is believed to be the worlds longest underground transmission system and cost more than A$177 million. It was built by TransEnergie Australia, a subsidiary of Hydro-Québec. It was sold to the Australian Pipeline Trust (APA Group) in March 2006 for A$153 million. In December 2008 ownership of Murraylink (as well as Directlink) was transferred to the newly formed Energy Infrastructure Investments Group, while APA continued as the operator.[1] The ownership of EII is APA with 19.9%, with the balance with Japan-based Marubeni Corporation with 49.9% and Osaka Gas with 30.2%.[2] CapacityMurraylink consists of two {{convert|180|km|adj=on}} long bipolar HVDC cables.[3] The circuit has an operating voltage of 150 kV and a transmission capacity of 220 megawatts. The link operates an "HVDC Light" voltage-source converter system, utilising insulated-gate bipolar transistors (IGBT), to convert electricity between alternating current and direct current. While Murraylink is rated at 220MW, it is unable to operate at capacity during periods of high demand due to limitations in the transmission infrastructure at either end.[4] The limitations relate to thermal overload of transformers or transmission lines supplying the Riverland (for South Australia to Victoria transmission) and western Victoria (for Victoria to South Australia transmission).[5] Sites
