158th largest plant in Michigan · 5937th nationally
Marshall (Mi) is a hydroelectric power plant in Michigan with a nameplate capacity of 9.8 MW. It generates roughly 611 MWh per year — enough to power about 58 average U.S. homes.
Its capacity factor of 1% reflects intermittent or peaking operation. At 654 lb CO₂/MWh, its emission rate sits below the national grid average of roughly 800 lb/MWh.

Hydroelectric plants spin turbines using falling or flowing water — typically from a dam-impounded reservoir. They are dispatchable, long-lived, and emission-free at the point of generation, though large reservoirs can disrupt rivers and ecosystems and methane can be released from flooded vegetation.
