Brayton Point Power Station, is a coal-fired power plant located in Somerset, Massachusetts, USA, which had been owned by the power company Dominion Energy New England since 2005 after it was purchased from PG&E. The plant was owned from August 2013 to April 2015 by Energy Capital Partners and is now owned by Dynegy. First starting operations in the 1960s, the power station is one of the largest in New England, standing on a 306-acre site,〔(【引用サイトリンク】url=https://www.dom.com/about/stations/fossil/brayton-point-power-station.jsp )〕 with 262 full-time staff, with four power generating units powering in the region of 1.5 million homes using coal, natural gas and oil as its fuel sources. Its output from the four units are: *Unit 1: 243 megawatts〔 *Unit 2: 240 megawatts *Unit 3: 612 megawatts *Unit 4: 435 megawatts Brayton Power Station has been estimated to burn 40,000 tons of coal in three days, and fresh supplies are brought by barge every four days. The coal is brought from Colombia, Kentucky, and Colorado.〔 ==Environmental improvements== With regulations and concerns from the public, Dominion agreed to make investments to improve in the environmental impacts of the plant in two areas. The first area was to decrease emissions of mercury, sulfur oxide and nitrogen oxide through the implementation of a system called ''Novel Integrated Desulphurization'' (NID). The NID injects lime to allow its reaction with the fumes to separate chemicals from the smoke which reduces the emissions of mercury and sulfur oxide. The company also implemented another system to pass the fumes through ammonia to reduce nitrogen oxide emission. The company reported having reduction of those emissions by 90 percents after the installation. The other area was to reduce the impact on the water consumption and the release of heated water which killed the fish. Dominion began construction of two 500-foot cooling towers in 2009, which were completed in 2013. This was to create a close-cycle water cooling system whereby the heated water is cooled by the towers and the water is recycled back to be used in the system again. This stopped the heated water to be released back to Mount Hope Bay. 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「Brayton Point Power Station」の詳細全文を読む スポンサード リンク
