8th largest plant in Rhode Island · 4035th nationally
Johnston Lfg Turbine Plant is a biomass power plant in Rhode Island with a nameplate capacity of 35.7 MW. It generates roughly 231.0k MWh per year — enough to power about 22,002 average U.S. homes.
Its capacity factor of 74% puts it in the middle range — running steadily but not full-time.
Ghost bars are each month's theoretical maximum (35.7 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.
