WasteWashingtonUnited States of AmericaCO₂ modelled
Spokane Waste to Energy is a 26 MW waste power plant in Washington, United States of America. It is operated by City of Spokane. Based on reported annual generation of 121 GWh, it can supply roughly 35k homes. It ranks #4391 of 10,884 United States of America power plants by installed capacity. Commissioned in 1991, it is around 35 years old — long-established. Its modelled annual emissions are 184,500 t CO₂/yr (Climate TRACE), equivalent to about 43k 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 Mediterranean continental climate (Köppen Dsb) — Northern Hemisphere, latitude 47.6°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 43% 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: 76/100 — 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.
