The Anglesea Power Station is a brown coalpowered thermal power station located at Anglesea, in Victoria, Australia within the floristically rich Anglesea Heath area. The station has one steam turbine with a capacity of of electricity, previously supplying almost 40% of the electricity used by the nearby Point Henry aluminium smelter, operated by Alcoa of Australia. following its closure in 2014. The power station was brought online on 20 March 1969,〔''R. Arklay and I. Sayer'' - 'Geelong's Electric Supply' - September 1970〕 and is supplied with coal by the adjacent open cut mine, transported to the power station along a long private road. Overburden is stripped and backfilled into the mined area by earthmoving contractors using conventional power shovels and trucks. About 80 people work at the coal mine and power station.〔Murphy, Noel, 20 February 2014, ''(80 jobs in doubt at Alcoa’s Anglesea power station )'', The Independent, Retrieved 28 August 2014〕 Alcoa announced in June 2015 that he power plant and mine will close at the end of August 2015, after the company was unable to find a buyer following the closure of the Port Henry aluminium smelter in 2014. As of late August 2015 the power station ceased generation for the grid and will be cease operation by September. Mine rehabilitation, plant decommissioning and demolition will occur progressively thereafter. ==History== From 1955 test bores for coal were made at Anglesea by the Roche Brothers, who were then operating a mine at nearby Wensleydale where the coal reserves were dwindling. An extensive coal deposit was found two kilometres to the north of the Anglesea township, with mining commencing in 1959 to supply brown coal to industry and institutions in the Geelong area. The mining rights were taken over by Western Mining Corporation (WMC) in 1961 to supply the power station planned by Alcoa of Australia. The Mines (Aluminum Agreement) Act of 1961 granted Alcoa a 50year exclusive right to explore and mine over some of leasehold land in the region. After further drilling investigation WMC relocated the mining operation to the east of the original mine, closer to the power station site and providing access to a larger coal reserve of . The total thickness of the coal seams is about , with total economic mineable reserves estimated at in the upper seam, and a further in lower seams. In 1992 the overburden to coal ratio averaged around 2.5 to 1, with an average coal thickness of .〔 Following negotiation with the Victorian government in 2011, Alcoa took up a 50year extension of the Agreement under the Mines (Aluminium Agreement) Act 1961, allowing for continued operation of the mine and power station until 2016.〔Soames, Nicholas, 25 October 2011, ''(Alcoa Anglesea Mine Agreement Extended For Another 50 Years )'' Surf Coast News, Retrieved 28 August 2014〕 Alcoa has outlined plans to expand the footprint of the mine by approximately 50 percent, taking the total disturbed area from approximately , from about 2016.〔Baker, Richard, 21 March 2011 ''(Alcoa mine could take heritage heathland )'' The Age, Retrieved 28 August 2014〕 As of 2005 approximately of coal had been mined, with about of brown coal mined annually to feed a boiler that consumes of pulverised brown coal an hour. The coal at Anglesea has a high quality heat value when compared to other brown coals used to produce electricity in Victoria, but has a much higher level of sulphur of around 3%, resulting in high levels of sulfur dioxide (SO2) emissions. Carbon Monitoring for Action estimates this power station emits of greenhouse gases each year as a result of burning coal.〔(【引用サイトリンク】 title=Anglesea )〕 Anglesea draws its cooling water from six sub-artesian well bores, supplemented with rainwater. With the closure of the Point Henry Aluminium smelter, Alcoa applied for and was granted a licence in May 2014 by the Essential Services Commission to sell electricity to the National Electricity Market. It is widely believed that Alcoa is looking for a buyer of the power station and coal mine, An Alcoa spokesperson said in February 2014 "Alcoa believes the Anglesea power station is a viable asset and that is why it will be offered for sale. If a sale is not possible, we will evaluate options at that time, including possible closure.”〔 In May 2015, Alcoa announced that it was unable to find a buyer for the plant, and would close it and the associated coal mine in August 2015.〔 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「Anglesea Power Station」の詳細全文を読む スポンサード リンク
