Whitewater Generating Station

🔥 Natural GasElectric Utility283 MW capacity

19th largest plant in Wisconsin · 1120th nationally

Whitewater Generating Station is a natural gas power plant in Wisconsin with a nameplate capacity of 284 MW. It generates roughly 663.9k MWh per year — enough to power about 63,226 average U.S. homes.

Its capacity factor of 27% reflects intermittent or peaking operation. At 943 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.

About Natural Gas plants

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.
