WindIowaUnited States of America

Pomeroy Wind Farm is a 286 MW wind power station in Iowa, United States of America. It is operated by MidAmerican Energy Co. Based on reported annual generation of 714 GWh, it can supply roughly 204,142 homes. It ranks #996 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 42.6°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 55% 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.
