WindOklahomaUnited States of America

Dempsey Ridge Wind Farm is a 132 MW wind power station in Oklahoma, United States of America. It is operated by Acciona Wind Energy USA LLC. Based on reported annual generation of 344 GWh, it can supply roughly 98,314 homes. It ranks #1650 of 9,833 United States of America power plants by installed capacity. Commissioned in 2012, it is around 14 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 humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 35.5°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 17% below 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: 43/100 — 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.
