74th largest plant in Michigan · 3434th nationally
A.j. Mihm Generating Station is a natural gas power plant in Michigan with a nameplate capacity of 56.4 MW. It generates roughly 207.9k MWh per year — enough to power about 19,799 average U.S. homes.
Its capacity factor of 42% puts it in the middle range — running steadily but not full-time. At 986 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.

Natural gas plants are the workhorse of the modern grid. Combined-cycle units achieve very high efficiency and can ramp up and down quickly to balance variable renewables. They emit roughly half the CO₂ per MWh of coal and far less of other pollutants, but they still release upstream methane during fuel extraction.
