Wind power plant in Wisconsin, United States of America. Approximate location 43.8794, -88.2708.

WindWisconsinUnited States of America

Blue Sky Green Field Wind Project is a 145.2 MW wind power station in Wisconsin, United States of America. It is operated by Wisconsin Electric Power Co. Based on reported annual generation of 322 GWh, it can supply roughly 92k homes. It ranks #2339 of 10,884 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).

In context: how this plant compares

At 145.2 MW, Blue Sky Green Field Wind Project is well above the median wind plant in United States of America (67.7 MW). Wind turbines convert moving air into electricity; output is variable and site-dependent, and modern turbines deliver some of the lowest-cost new generation on many grids.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

This wind plant converts the kinetic energy of wind into electricity through turbine rotors. It sits in a warm-summer humid continental climate (Köppen Dfb) — 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 68% 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: 86/100 — this site sits in the top third of the power plants we cover by heating degree-days.

Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.

Site climate & environmental severity

This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with thermal cycling the leading environmental stress.
