Wind power plant in Kansas, United States of America. Approximate location 37.8641, -99.7528.
WindKansasUnited States of America
Spearville is a 148 MW wind power station in Kansas, United States of America. It is operated by Evergy Metro. Based on reported annual generation of 374 GWh, it can supply roughly 106,742 homes. It ranks #1570 of 9,833 United States of America power plants by installed capacity. Commissioned in 2007, it is around 19 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).

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 37.9°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 8% 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: 53/100 — this site sits in the mid 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.
