9th largest plant in Wisconsin · 595th nationally
Fox Energy Center is a natural gas power plant in Wisconsin with a nameplate capacity of 619 MW. It generates roughly 4.3M MWh per year — enough to power about 413,991 average U.S. homes.
Its capacity factor of 80% means it runs nearly around-the-clock as baseload generation. At 822 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (619 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.
