MHKW Mainz is a 16 MW waste power plant in Rheinland-Pfalz, Germany. It is operated by Entsorgungsgesellschaft Mainz mbH. Based on its capacity (estimated), it can supply roughly 21k homes (estimated). It ranks #671 of 1,442 Germany power plants by installed capacity. Commissioned in 2009, it is around 17 years old — relatively modern. Its annual emissions of 381,097 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 89k cars driven for a year. In context, the national grid averages 330 gCO₂/kWh (59.1% low-carbon) (2025).

At 16 MW, MHKW Mainz is below the median waste plant in Germany (22 MW). Waste-to-energy plants burn municipal solid waste to generate electricity and heat, cutting landfill volume while recovering energy from residual waste.

This waste plant recovers energy by combusting municipal or industrial waste. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 50.0°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 19% 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: 60/100 — this site sits in the mid 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 humidity / wetness 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 #44 largest waste power plant of 68 in Germany by capacity.
Germany has 68 waste power plants in this dataset, together about 1,698 MW of capacity.
