Marianske Hory power station — Czech Republic

Marianske Hory power station is a 30 MW coal power plant in Moravian-Silesian, Czech Republic. It is operated by Veolia Energie ČR AS [100%]. Based on its capacity (estimated), it can supply roughly 38k homes (estimated). It ranks #50 of 481 Czech Republic power plants by installed capacity. Commissioned in 1970, it is around 56 years old — an older, legacy facility. Its annual emissions of 112,604 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 26k 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 30 MW, Marianske Hory power station is below 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.

Climate zone & how it works

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 49.9°N — which shapes how much energy it can produce and how its output varies through the year.

Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).

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.
