Tatabanya power station is a 21 MW gas power plant in Tatabanya, Hungary. It is operated by Tatabánya Eromu Kft. Based on its capacity (estimated), it can supply roughly 24k homes (estimated). It ranks #33 of 37 Hungary power plants by installed capacity. Commissioned in 2004, it is around 22 years old — relatively modern. Its annual emissions of 16,454 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 3.8k cars driven for a year. In context, gas supplies about 20.3% of Hungary's electricity; the national grid averages 163 gCO₂/kWh (75.3% low-carbon) (2025).

In context: how this plant compares
At 21 MW, Tatabanya power station is below the median gas plant in Hungary (110 MW). Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

Climate zone & how it works
This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 47.6°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.
