82nd largest plant in Michigan · 3730th nationally
Alpena Cement Plant is a oil power plant in Michigan with a nameplate capacity of 47.2 MW. It generates roughly 187.7k MWh per year — enough to power about 17,877 average U.S. homes.
Its capacity factor of 45% puts it in the middle range — running steadily but not full-time. At 1460 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (47.2 MW nameplate × hours in the month). Filled bars are actual net generation reported to EIA Form 923. The gap between them is capacity factor made visible.

Oil-fired plants typically run only during peak demand or grid emergencies because oil is expensive compared to gas and coal. They have the highest CO₂ emissions per MWh of any common generation technology.
