OilIowaUnited States of AmericaCO₂ reported

Webster City is a 21 MW oil power plant in Iowa, United States of America. It is operated by City of Webster City - (IA). Based on reported annual generation of 1 GWh, it can supply roughly 200 homes. It ranks #3619 of 9,833 United States of America power plants by installed capacity. Commissioned in 1972, it is around 54 years old — an older, legacy facility. Its measured emissions of 13,988 t CO₂/yr (Climate TRACE) are equivalent to about 3,261 cars driven for a year. In context, oil supplies about 0.7% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a hot-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 42.5°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 56% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.

Climate heat-demand index: 82/100 — this site sits in the top third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.
