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 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. ==Features and capacity== Wallerawang was originally built with four British Thompson Houston single cylinder generators, completed in 1957-1959. Steam was supplied to each generator by a John Thompson 'Etaflow' boiler at a rate of at and . This was referred to as Wallerawang A. Wallerawang B consisted of two General Electric 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 at and . Wallerawang A and B have both been decommissioned. The two 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 other was also mothballed 15 months later. 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wallerawang Power Station」の詳細全文を読む スポンサード リンク
