WasteIowaUnited States of America
Lake Mills Gas Recovery is a 4 MW waste power plant in Iowa, United States of America. It is operated by WM Renewable Energy LLC. Based on reported annual generation of 17 GWh, it can supply roughly 4.8k homes. It ranks #7624 of 10,938 United States of America power plants by installed capacity. Commissioned in 2006, it is around 20 years old — relatively modern. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This waste plant recovers energy by combusting municipal or industrial waste. It sits in a hot-summer humid continental climate (Köppen Dfa) — Northern Hemisphere, latitude 43.4°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 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.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with thermal cycling the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
The #381 largest waste power plant of 551 in United States of America by capacity.
United States of America has 551 waste power plants in this dataset, together about 10,154 MW of capacity.
