. It is owned by the DTE Energy Electric Company, a subsidiary of DTE Energy. The plant was constructed in the early 1970s and began operating in 1971. The plant has 4 generating units, each with an output of 850 megawatts. With all four generating units operating, the plant's total output is 3,300 megawatts (3,400 MW total, with 100 MW required for the plant machinery to run). This makes it the eleventh largest electric plant in the United States. The Monroe Power Plant connects to the power grid by numerous 120,000- and 345,000-volt
