CMS Energy (), based in Jackson, Michigan, is an energy company that is focused principally on utility operations in Michigan. Its principal business is Consumers Energy, a public utility that provides electricity and natural gas to more than 6 million of Michigan’s 10 million residents. Its non-utility businesses are focused primarily on domestic independent power production. Consumers Energy has operated since 1886. CMS Enterprises' primary businesses are independent power production and natural gas transmission. CMS Energy is a member of the S&P 500 and the Fortune 1000.〔(【引用サイトリンク】 title=Ally Financial Larger Than S&P 500 Component CMS Energy )〕 ==History== CMS Energy was formed in 1987 as a holding company with its principal subsidiaries as Consumers Energy and CMS Enterprises. On October 23, 1987, CMS Energy became a publicly owned company and was listed at the New York Stock Exchange. The company’s history dates back to 1886, when William Augustine Foote and Samuel Jarvis initially approached Jackson, Michigan officials and asked them to support efforts to illuminate Jackson’s downtown with electric arc lights. With the early success of their first project, they formed a company, Jackson Electric Light Works in 1888 to focus on the large scale energy projects. In 1889, Foote and Jarvis built their first large scale hydro plant project at the Trowbridge Dam on the Kalamazoo River. Foote, after seeing some early success, began consolidating his small power companies and formed Commonwealth Power Company.〔 In 1907, Foote and Jarvis built Croton Hydro project on the Muskegon River, the first project in the world that could transmit 110,000 volts of electricity. They focused on expanding their power business and its reach. In 1920, Foote and Jarvis offered preferred shares of their company to the public to secure sufficient financing to enter other energy and power generation sectors.〔(【引用サイトリンク】 title=Consumers Power Co. - Company Profile, Information, Business Description, History, Background Information on Consumers Power Co. )〕 Over the next several decades the company built several coal-fired, natural gas, nuclear and electric facilities. In 1946, the company formed a strategic partnership with Panhandle Company to convert former natural gas fields to underground natural gas storage areas. CMS Energy’s primary subsidiary, Consumers Energy, announced Michigan's first nuclear power plant in 1961, Big Rock Point in Charlevoix, Michigan. The plant was capable of producing 67 megawatts of electricity. The plant's construction was completed in 2.5 years and electricity was first generated December 8, 1962. Generation continued until August 29, 1997. The company announced another nuclear plant, Palisades Nuclear Generating Station on Lake Michigan,〔(【引用サイトリンク】 title=Palisades Power Plant )〕 which first produced electricity in December, 1971 to serve 400,000 people a day. CMS Energy owned the plant until 2006, when it was sold to Entergy. It then announced a gas reforming plant to furnish heat for Michigan homes in 1971. This plant was the first of its kind in North America to produce synthetic gas, converting impure liquid petroleum into pipeline-quality natural gas. In 1987, CMS Energy, a holding company with its principal subsidiaries as Consumers Power and CMS Enterprises was formed. Consumers Power was rebranded Consumers Energy in 1997. The firm was one of the first companies to introduce an online billing system in the late 1990s, and its billing system was named to the 2000 Information Technology Innovation Collection by Smithsonian National Museum. In 2001, the firm entered into an exploration agreement with Eritrea for oil exploration in the Dismin Block of the Red Sea.〔(【引用サイトリンク】 title=Eritrea has Petroleum Oil and Gas )〕 In 2003, the firm moved its headquarters to One Energy Plaza in Jackson, Michigan. In 2007, the company announced plans to invest $6 billion in Michigan’s energy future to support new power plant technology and identify new energy sources. In 2014, Consumers Energy opened Cross Winds Energy Park in Michigan’s Tuscola County and signed a contract with General Electric to supply 621.79-megawatt wind turbine engines for the project. 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「CMS Energy」の詳細全文を読む スポンサード リンク
