Wallerawang Power Station was a thermal coal power station, located near Wallerawang, in the Central Tablelands region of New South Wales, Australia. The power station was equipped with two turbo-alternators of 500 megawatts (670,000 hp) each, supplied by C. A. Parsons and Company of Newcastle-upon-Tyne, England.

In July 2013, EnergyAustralia, a subsidiary of CLP Group, acquired Wallerawang Power Station, along with Mount Piper Power Station, from Delta Electricity for A$160 million. Due to dwindling demand, the first of the two generating units had been mothballed in January 2013, and the second in April 2014. In November 2014, EnergyAustralia announced that it would permanently close Wallerawang due to ongoing reduced energy demand, lack of access to competitively priced coal and the power station’s high operating costs.EnergyAustralia began the process of removing useful equipment from the station in 2015 and began demolition of the site when this process has been completed.

Wallerawang A — originally built with four British Thompson Houston 30 megawatts (40,000 hp) single cylinder generators, completed in 1957-1959. Steam was supplied to each generator by a John Thompson 'Etaflow' boiler at a rate of 150,000 kilograms per hour (330,000 lb/h) at 600 pounds per square inch (4,100 kPa) and 540 °F (282 °C). Wallerawang A was decommissioned in May 1986.

Wallerawang B — comprised two General Electric 60 megawatts (80,000 hp) 2–cylinder turbines with hydrogen cooled generators completed in 1961. Steam was supplied to each generator by a John Thompson boiler at a rate of 270,000 kilograms per hour (600,000 lb/h) at 900 pounds per square inch (6,200 kPa) and 900 °F (482 °C). Wallerawang B was decommissioned in 1990.

Wallerawang C — comprised two 500 megawatts (670,000 hp) units were completed in 1976 and 1980. Due to dwindling energy demand, in January 2013 the NSW government-owned corporation, Delta Electricity, mothballed one of the two remaining units of Wallerawang C for twelve months. The other was also mothballed 15 months later.
