60th largest plant in South Carolina · 4487th nationally
Allendale Biomass is a biomass power plant in South Carolina with a nameplate capacity of 22.5 MW. It generates roughly 121.0k MWh per year — enough to power about 11,521 average U.S. homes.
Its capacity factor of 61% puts it in the middle range — running steadily but not full-time.
Ghost bars are each month's theoretical maximum (22.5 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.
