The Monroe Coal Power Plant is a coal-fired power plant located / 41.88917; -83.34556 in Monroe, Michigan on the western shore of Lake Erie. Monroe Coal Power Plant is owned by the Detroit Edison Company, a subsidiary of DTE Energy. The plant was constructed in the early 1970s and was completed in 1974. The plant has 4 generating units, each with an output of 850 megawatts. With all four generating units operating, the plants total output is 3,300 megawatts, the eleventh largest electric plant in the United States. It is the second largest coal fired plant in the United States after Georgia Power's Plant Bowen near Cartersville, Georgia.

The Monroe Coal Power Plant did significant upgrades and maintenance at the facility in late 2007 and 2008. FGD's, or Sulfur-oxide "scrubbers", are in the process of being added to all of Monroe's generating units. These devices significantly reduce emitted SO2, and will be eventually installed in more of Detroit Edison's coal plants.

The Monroe Coal Power Plant connects to the power grid by numerous 120,000 and 345,000 volt transmission lines, owned and maintained by International Transmission Company (ITC). Two of the 345kv lines going out of the plant interconnect with First Energy in Ohio (Bayshore-Monroe line and the Majestic-Monroe-Allen Junction Line).
