WindSouth DakotaUnited States of America

Prairie Winds SD1 is a 162 MW wind power station in South Dakota, United States of America. It is operated by Basin Electric Power Coop. Based on reported annual generation of 397 GWh, it can supply roughly 113,314 homes. It ranks #1454 of 9,833 United States of America power plants by installed capacity. Commissioned in 2011, it is around 15 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 43.9°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 60% 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: 83/100 — 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.
