Features and Capacity
Wallerawang was originally built with four 30 megawatts (40,000 hp) generators, completed in 1957-1959, which were referred to as Wallerawang A. Wallerawang B consisted of two 60 megawatts (80,000 hp) generators completed in 1961. Wallerawang A and B have both been decommissioned. The two 500 megawatts (670,000 hp) units in the current 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 coal for Wallerawang Power Station comes from mines in the local area, delivered by private road. 75% of the coal comes from the Centennial Coal-owned Angus Place colliery.
Wallerawang Power Station draws its cooling water from Lake Wallace and Thompson's Creek dam, fresh water lakes on the Coxs River. Water from Lake Lyell and mine dewatering projects can also supply water in times of shortage. In 2007 and in 2009, water shortages occurred in the Fish River system, causing concern that the generating facility would be forced to close. Oberon Shire was also concerned about the level of potable water available from the Oberon Dam, a water cooling source for Wallerawang Power Station.

Famous quotes containing the words features and/or capacity:
“The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
—Marcel Proust (1871–1922)
“It is part of the educator’s responsibility to see equally to two things: First, that the problem grows out of the conditions of the experience being had in the present, and that it is within the range of the capacity of students; and, secondly, that it is such that it arouses in the learner an active quest for information and for production of new ideas. The new facts and new ideas thus obtained become the ground for further experiences in which new problems are presented.”
—John Dewey (1859–1952)
