WindIowaUnited States of America

Osceola Windpower II is a 50 MW wind power plant in Iowa, United States of America. It is operated by Osceola Windpower II. Based on reported annual generation of 151 GWh, it can supply roughly 43,200 homes. It ranks #2783 of 9,833 United States of America power plants by installed capacity. Commissioned in 2008, it is around 18 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, wind supplies about 10.3% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a hot-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 43.4°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 72% 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: 87/100 — 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.
