24th largest plant in Arkansas · 1839th nationally
Ashdown is a biomass power plant in Arkansas with a nameplate capacity of 157 MW. It generates roughly 496.2k MWh per year — enough to power about 47,258 average U.S. homes.
Its capacity factor of 36% reflects intermittent or peaking operation. At 194 lb CO₂/MWh, its emission rate sits below the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (157 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.
