Owned and operated by EnergyAustralia, the station is the first of its type in New South Wales and produces electricity for the state during periods of high demand. It is located on the western shore of Lake Illawarra in the suburb of Yallah.

The station comprises a 260-megawatt (350,000 hp) gas turbine and a 160-megawatt (210,000 hp) steam turbine unit and has a total capacity of 435 megawatts (583,000 hp). It uses many of the previous power station's structures including the cooling system channels from Lake Illawarra.
