🔥 Natural GasIndustrial CHP40 MW capacity

114th largest plant in Iowa · 3890th nationally

Cargill Corn Milling Division is a natural gas power plant in Iowa with a nameplate capacity of 40.0 MW. It generates roughly 76.3k MWh per year — enough to power about 7,266 average U.S. homes.

Its capacity factor of 22% reflects intermittent or peaking operation. At 656 lb CO₂/MWh, its emission rate sits below 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.
