86th largest plant in Michigan · 3967th nationally
Grayling Generating Station is a biomass power plant in Michigan with a nameplate capacity of 38.6 MW. It generates roughly 134.1k MWh per year — enough to power about 12,773 average U.S. homes.
Its capacity factor of 40% reflects intermittent or peaking operation.
Ghost bars are each month's theoretical maximum (38.6 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.

Biomass plants burn wood, agricultural waste, or methane from landfills to generate steam and electricity. They are considered carbon-neutral over long timescales when fuel is sustainably sourced, but they produce particulate emissions similar to coal.
