WindWyomingUnited States of America

Silver Sage Windpower is a 42 MW wind power plant in Wyoming, United States of America. It is operated by Duke Energy DEGS Silver Sage Wndpwr LLC. Based on reported annual generation of 120 GWh, it can supply roughly 34,285 homes. It ranks #2961 of 9,833 United States of America power plants by installed capacity. Commissioned in 2009, it is around 17 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 cold semi-arid steppe climate (Köppen BSk) — Northern Hemisphere, latitude 41.1°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 59% 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.
