The Detroit Edison Company, founded in 1903, is an investor-owned electric utility which serves most of Southeast Michigan. Its parent company, DTE Energy (NYSE: DTE), provides energy services to a variety of clients beyond Detroit Edison's service area.
History
Detroit Edison was part of a large holding company called North American Edison Company. North American's stock had once been one of the twelve component stocks of the May 1896 original Dow Jones Industrial Average.[1] North American Company was broken up by the Securities and Exchange Commission, following the United States Supreme Court decision of April 1, 1946.
After that Detroit Edison operated independently, and publicly traded on the New York Stock Exchange, under the ticker symbol DTE through the mid 1990s. In early 1996, it became an operating subsidiary of the new holding company, DTE Energy Company, which replaced Detroit Edison Company on the stock exchange, and took over the trading ticker symbol.[2]

The utility operates eleven fossil-fuel generating plants, as well as the Enrico Fermi Nuclear Generating Station. The company is co-owner, with Consumers Energy, of the Ludington Pumped Storage Power Plant, a hydroelectric pumped storage facility in Ludington, Michigan. Detroit Edison uses fossil fuels (mainly coal) to generate 80-85 percent of its total electrical output, with the bulk of the remainder coming from nuclear power.[3]
At 3,300 megawatts, Detroit Edisons's Monroe Power Plant has the third largest generating capacity of any coal-fired power plant in North America. Only Georgia Power's Plant Bowen located near Atlanta, Georgia and Ontario Power Generation's Nanticoke Generating Station in Canada have more generating capacity.
Detroit Edison operates the coal-fired St. Clair and Belle River Power Plants in East China, Michigan and the Marysville Power Plant near Port Huron, all on the shores of the St. Clair River. Also in St. Clair County lies the Greenwood Energy Center, a natural gas and fuel oil plant. Farther north in Harbor Beach is the Harbor Beach Power Plant.
On the Detroit River, Detroit Edison operates the Conners Creek Power Plant in the City Of Detroit, the River Rouge Power Plant and the Trenton Channel Power Plant, which all burn coal.
Energy transmission
Due to electric utility deregulation in Michigan, DTE Energy was forced to sell off Detroit Edison's sister subsidiary involved in high-voltage energy transmission: International Transmission Co. (ITC)
Energy distribution
Detroit Edison's near 11-gigawatt generating capacity is offered to its 7,600-square-mile (20,000 km2) service area, which encompasses 13 counties in the southeastern portion of Michigan's lower peninsula. Energy is distributed throughout Huron, Tuscola, Sanilac, Saint Clair, Lapeer, Livingston, Ingham, Oakland, Macomb, Wayne, Washtenaw, Lenawee and Monroe counties by over a million utility poles and 44,000 miles (71,000 km) of power lines.
Detroit Edison's distribution line voltages are three-phase 4,800 Δ volts and 7,620/13,200 Y volts. All new distibution circuits constructed after 1959 are 13,200 volts.
