Munmorah Power Station

Munmorah Power Station is a demolished coal fired electricity power station with four 350 MW English Electric steam driven turbo-alternators for a combined capacity of 1,400 MW. The station was located near Doyalson, on the shores of Lake Munmorah, New South Wales, Australia and was owned and operated by Delta Electricity, a company owned by the New South Wales Government.In July 2012 the coal-fired generators were permanently retired from service. However, the nearby gas-fired Colongra power station, which was commissioned in 2009, remains in operation.History and facilitiesThe station was constructed with 4 English Electric 350 MW turbo-alternators. Munmorah had a total capacity of 1,400 MW. Steam was supplied at a pressure of 2,500 psi and a temperature of 460 °C. One unit was completed in 1967, another in 1968, and the remaining two in 1969. Units 3 and 4 had fabric filters fitted in the 1980s, and this reduced load to 320 MW each. Units 1 and 2 were relegated to emergency use from 1992.Munmorah drew salt water from Lake Munmorah, part of the Tuggerah Lakes, for condenser cooling. The coal for Munmorah came from two underground mines, Munmorah State mine and Newvale No.2 Colliery, and also from Vales Point coal storage via a series of conveyor belts.
