Detroit Edison, founded in 1903, is an investor-owned electric utility which serves most of Southeast Michigan. Its parent company, DTE Energy, provides energy services to a variety of clients beyond Detroit Edison's service area.
Power generation The utility operates nine fossil-fuel generating plants, as well as the Fermi 2 nuclear power plant. The company also is co-owner with Consumers Energy Co. of a hydroelectric pumped storage facility in Ludington, Michigan. Detroit Edison uses coal to generate about 85 percent of its total electrical output, with the remainder produced from nuclear fuel and natural gas. At 3,300 megawatts, Detroit Edisons's Monroe Power Plant has the second largest generating capacity of any coal-fired powerplant in North America. Only Southern Company's Bowen Power Plant located near Atlanta, Georgia has more generating capacity. Energy transmission Due to electric utilitysubsidiary involved in high-voltage energy transmission: International Transmission Co. (ITC) Electric grid interconnections Detroit Edison has three 345KV interconnections with First Energy Corporation in Ohio. (Bayshore-Monroe line, Majestic-Monroe-Allen Junction line, and the Majestic-Lemoyne line). There are four 345KV interconnections with Consumers Energy to the west of Detroit Edison's service area. (Majestic-Tompkins line, Majestic-Battle Creek-Oneida line, Jewell-Thetford line, and the Pontiac-Hampton line) There are two 345KV interconnections with Hydro One in Ontario, Canada. (St. Clair-Lambton There are two 230KV interconnections with Hydro One in Ontario, Canada. (Keith-Waterman line and the Bunce Creek-Scott line} There are five 120KV interconnections with Consumers Energy. Since Consumers Energy/METC's transmission voltage is 138KV, Detroit Edison has 120/138 KV transformers in the substations on their end of the lines so that they can tie into Consumers Energy's system. The 120/138KV interconnections are the Custer-Whiting line, Genoa-Latson line, Hemphill-Hunters Creek line, Washtenaw-Lark-Blackstone line and the Atlanta-Thetford-Karn line. | ||||||||
