Tallawarra Power Station is a 435 MW combined cycle natural gas power station〔(【引用サイトリンク】title=Tallawarra Power Station )〕 in the city of Shellharbour, New South Wales, Australia. Owned and operated by EnergyAustralia, the station is the first of its type in New South Wales〔(【引用サイトリンク】 title=Tallawarra power station )〕 and produces electricity for the state during periods of high demand.〔(【引用サイトリンク】 title=Tallawarra Power Station FAQs )〕 It is located on the western shore of Lake Illawarra in the suburb of Yallah. The station comprises a 260 MW gas turbine and a 160 MW steam turbine unit〔 and has a total capacity of 435 MW.〔 It uses many of the previous power station's structures including the cooling system channels from Lake Illawarra. The power station is connected to the state grid via a 132 kV switching station maintained by Integral Energy. TRUenergy has also indicated that an additional power plant is being considered for the site, to be known as Tallawarra B.〔 ==History== Tallawarra originally operated as a coal-fired power station beginning in 1954 and reaching full operation by 1961.〔(【引用サイトリンク】 title=Yallah History ) 〕 At its peak, it had a capacity output of 320 MW. 'A' station had four 30 MW Thomson-Houston 2 stage (HP+LP) turbo generators. Steam was supplied by four Simon Carves pulverised fuel boilers at at a pressure of and a temperature of . In 1960 "B" station was built having two 100 MW English Electric 3-stage turbo generators (No5+6). The generators were hydrogen-cooled but didn't have any stator water cooling. Steam was supplied by 2 ICAL pulverised coal burning boilers at a rate of at a pressure of and a temperature of . The station closed in 1989, and stood abandoned by the foreshore of Lake Illawarra. It was demolished over a ten-year period.〔(【引用サイトリンク】 title=Transforming Tallawarra: GT26 based plant for booming New South Wales )〕 In early 2003 the site was sold by Pacific Power to TRUenergy (then known as TXU) and construction of the gas-fired combined cycle plant began in November 2006. The plant consists of a gas turbine of 288 MW and a 3-stage steam turbine of 160 MW with a single 450 MW generator. A unique feature is the waste heat boiler with a super heater and two reheater sections for the IP and LP stages of the turbine. Overall thermal efficiency is 60%.〔(【引用サイトリンク】 title=Tallawarra recent history )〕 It was opened by the NSW Premier Nathan Rees on 18 March 2009.〔(【引用サイトリンク】title=Tallawarra taking off in NSW )〕 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「Tallawarra Power Station」の詳細全文を読む スポンサード リンク
