Wallerawang Power Station is a thermal coal power station, located near Wallerawang, in the Central Tablelands region of New South Wales, Australia. The power station is equipped with two turbo-alternators of 500 megawatts (670,000 hp) each, supplied by C. A. Parsons and Company of Newcastle-upon-Tyne, England. Due to dwindling demand, the first of the two generating units was mothballed in January 2013, and the second in April 2014.
Wallerawang was 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). This was referred to as Wallerawang A.
Wallerawang B consisted of 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 A and B have both been decommissioned.
The two 500 megawatts (670,000 hp) units in the Wallerawang C station 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.
The coal for Wallerawang Power Station came from mines in the local area, delivered by private road. 75% of the coal comes from the Centennial Coal-owned Angus Place colliery.
