49th largest plant in South Dakota · 8730th nationally
Poet Biorefining - Hudson is a natural gas power plant in South Dakota with a nameplate capacity of 3.6 MW. It generates roughly 17.5k MWh per year — enough to power about 1,668 average U.S. homes.
Its capacity factor of 56% puts it in the middle range — running steadily but not full-time. At 720 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 (3.6 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.

Natural gas plants are the workhorse of the modern grid. Combined-cycle units achieve very high efficiency and can ramp up and down quickly to balance variable renewables. They emit roughly half the CO₂ per MWh of coal and far less of other pollutants, but they still release upstream methane during fuel extraction.
