Coal power plant in North Holland, Netherlands. Approximate location 52.4049, 4.8465.
CoalNorth HollandNetherlandsCO₂ measured
Hemweg power station is a 685 MW coal power station in North Holland, Netherlands. It is operated by NUON. Based on reported annual generation of 3,132 GWh, it can supply roughly 895k homes. It ranks #14 of 119 Netherlands power plants by installed capacity. Commissioned in 1995, it is around 31 years old — long-established. Its annual emissions of 636,535 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 148k cars driven for a year. In context, coal supplies about 7.1% of Netherlands's electricity; the national grid averages 254 gCO₂/kWh (54.2% low-carbon) (2025).

In context: how this plant compares
At 685 MW, Hemweg power station is below the median coal plant in Netherlands (1,040 MW). Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 52.4°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 23% 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: 63/100 — 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.
Site climate & environmental severity
This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), 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.
