Coal power plant in Ustecky, Czech Republic. Approximate location 50.4616, 14.38.
CoalUsteckyCzech RepublicsubcriticalCO₂ modelled
Steti Mondi power station is a 144 MW coal power station in Ustecky, Czech Republic. It is operated by Mondi Steti AS. Based on its capacity (estimated), it can supply roughly 180k homes (estimated). It ranks #28 of 481 Czech Republic power plants by installed capacity. Commissioned in 1973, it is around 53 years old — an older, legacy facility. Its modelled annual emissions are 342,920 t CO₂/yr (Climate TRACE), equivalent to about 80k cars driven for a year. In context, coal supplies about 35.2% of Czech Republic's electricity; the national grid averages 401 gCO₂/kWh (59.2% low-carbon) (2025).

In context: how this plant compares
At 144 MW, Steti Mondi power station is below the median coal plant in Czech Republic (165 MW). Technically it is described as subcritical. 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 50.5°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 30% 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: 68/100 — 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.
