Southern California Edison (or SCE Corp), the largest subsidiary of Edison International (), is the primary electricity supply company for much of Southern California, USA. It provides 14 million people with electricity across a service territory of approximately 50,000 square miles. However, the Los Angeles Department of Water and Power, San Diego Gas & Electric, Imperial Irrigation District, and some smaller municipal utilities serve substantial portions of the southern California territory. The northern part of the state is generally served by the Pacific Gas & Electric Company of San Francisco. Southern California Edison (SCE) still owns all of its electrical transmission facilities and equipment, but the deregulation of California's electricity market in the late 1990s forced the company to sell many of its power plants, though some were probably sold by choice. In California, SCE retained only its hydroelectric plants, totaling about 1,200 MW, and its 75% share of the 2,150-MW San Onofre Nuclear Generating Station, which has been shut down since January 2012; in June 2013 the company announced its intention to permanently close and decommission the nuclear plant. Also, SCE still owns about half of the 1,580-MW coal-fired Mohave Generating Station in Laughlin, Nevada, which supplied electricity to California, Nevada, and Arizona; Mohave closed in December 2005, amid concerns regarding water rights and coal supplies. The utility lost all of its natural gas-fired plants, which provided most of its electrical generation. The large, aging plants were bought by out-of-state companies such as Mirant and Reliant Energy, which allegedly used them to manipulate the California energy market.〔(【引用サイトリンク】Summary of FERC documentation relating to the Western Energy Crisis 2000-2001 )〕 Southern California Edison's power grid is linked to PG&E's by the Path 26 wires that generally follow Interstate 5 over Tejon Pass. The interconnection takes place at a massive substation at Buttonwillow. PG&E's and WAPA's Path 15 and Path 66, respectively, from Buttonwillow north eventually connect to BPA's grid in the Pacific Northwest. There are several other interconnections with local and out-of-state utilities, such as Path 46. In addition, SCE operates a regulated gas and water utility. SCE is the sole commercial provider of natural gas and fresh water service to Santa Catalina Island, including the city of Avalon, California. SCE operates the utilities under the names of Catalina Island Gas Company and Catalina Island Water Company. == History == The origins of the company lie with the grand scheme of magnate Henry E. Huntington and hydraulic engineer John S. Eastwood, developed around 1908, for a vast complex of reservoirs to be constructed in the Sierra Nevada Mountains of central California. Huntington founded Pacific Light and Power, one of the roughly two dozen companies he controlled at the time,〔http://www.huntington.org/uploadedFiles/Files/PDFs/pr_hugabouthenry.pdf〕 to execute what would eventually become one of the largest hydropower systems in the United States, the Big Creek Hydroelectric Project. Pacific Light and Power was one of the predecessor companies to SCE, along with Edison Electric, Mt. Whitney Power & Electric Co., California Electric Power Co., and others.〔http://hdl.huntington.org/cdm/landingpage/collection/p16003coll2〕 In November, 2014, Southern California Edison announced a partnership with Ice Energy to provide more efficient energy storage by freezing water at night when electricity is cheaper. In 2015, Southern California Edison began laying off American information technology employees and replacing them from H-1B visa immigrants from India; the lay off of American employees affected 400 individuals, and was due to the utility hiring Infosys for its information technology needs.〔 〕 The layoffs were questioned by members of the United States Senate. 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「Southern California Edison」の詳細全文を読む スポンサード リンク
