U.S. Steel Kosice Works power station is a 208 MW coal power station in Košice, Slovakia. It is operated by US Steel Košice sro [100%]. Based on its capacity (estimated), it can supply roughly 260k homes (estimated). It ranks #10 of 37 Slovakia power plants by installed capacity. Commissioned in 2008, it is around 18 years old — relatively modern. Its annual emissions of 5,375,510 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 1.3 million cars driven for a year. In context, coal supplies about 1.1% of Slovakia's electricity; the national grid averages 95 gCO₂/kWh (85.2% low-carbon) (2025).

In context: how this plant compares
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.

Climate zone & how it works
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 48.6°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.
How it compares & nearby plants
The #4 largest coal power plant of 4 in Slovakia by capacity.
