Murraylink

Capacity

Murraylink consists of two 176-kilometre (109 mi) long bipolar HVDC cables. 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. 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).
