Trmice — Czech Republic

Trmice is a 159 MW coal power station in Ustecky, Czech Republic. It is operated by CEZ Group. Based on its capacity (estimated), it can supply roughly 199k homes (estimated). It ranks #26 of 481 Czech Republic power plants by installed capacity. Its modelled annual emissions are 54,011 t CO₂/yr (Climate TRACE), equivalent to about 13k 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 159 MW, Trmice is around the median coal plant in Czech Republic (165 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 50.6°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 38% 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: 73/100 — 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.
