MHKW Pirmasens is a 15 MW waste power plant in Rheinland-Pfalz, Germany. It is operated by EEW Energy from Waste Saarbrücken GmbH. Based on its capacity (estimated), it can supply roughly 21k homes (estimated). It ranks #679 of 1,442 Germany power plants by installed capacity. Commissioned in 1999, it is around 27 years old — long-established. Its modelled annual emissions are 143,450 t CO₂/yr (Climate TRACE), equivalent to about 33k cars driven for a year. In context, the national grid averages 330 gCO₂/kWh (59.1% low-carbon) (2025).

Local climate & thermal context
This waste plant recovers energy by combusting municipal or industrial waste. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 49.2°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 33% 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: 70/100 — 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 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.
