Waste power plant in California, United States of America. Approximate location 39.1062, -122.1096.
WasteCaliforniaUnited States of AmericaCO₂ modelled
Wadham Energy LP is a 29.1 MW waste power plant in California, United States of America. It is operated by Wadham Energy Ltd Partners. Based on reported annual generation of 188 GWh, it can supply roughly 54k homes. It ranks #4289 of 10,884 United States of America power plants by installed capacity. Commissioned in 1989, it is around 37 years old — long-established. Its modelled annual emissions are 244,040 t CO₂/yr (Climate TRACE), equivalent to about 57k 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 hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 39.1°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 47% below 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: 30/100 — this site sits in the bottom 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 humidity / wetness 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.
