58th largest plant in Wyoming · 5480th nationally
Simplot Phosphates is a other fossil power plant in Wyoming with a nameplate capacity of 11.5 MW. It generates roughly 91.2k MWh per year — enough to power about 8,688 average U.S. homes.
Its capacity factor of 91% means it runs nearly around-the-clock as baseload generation. At 638 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 (11.5 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.
