Waste power plant in Wisconsin, United States of America. Approximate location 46.7353, -92.1517.
WasteWisconsinUnited States of AmericaCO₂ measured
M L Hibbard is a 72.8 MW waste power plant in Wisconsin, United States of America. It is operated by ALLETE Inc.. Based on reported annual generation of 22 GWh, it can supply roughly 6.2k homes. It ranks #3211 of 10,884 United States of America power plants by installed capacity. Commissioned in 1950, it is around 76 years old — an older, legacy facility. Its annual emissions of 13,102 t CO₂/yr (US EPA GHGRP) are equivalent to about 3.1k cars driven for a year. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

Local climate & thermal context
This waste plant recovers energy by combusting municipal or industrial waste. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 46.7°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 100% 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: 94/100 — 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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with thermal cycling the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
