Leopoldau power station is a 140 MW gas power station in Vienna, Austria. It is operated by Wien Energie GmbH [100%]. Based on its capacity (estimated), it can supply roughly 158k homes (estimated). It ranks #40 of 131 Austria power plants by installed capacity. Commissioned in 1975, it is around 51 years old — an older, legacy facility. Its annual emissions of 21,330 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 5.0k cars driven for a year. In context, gas supplies about 11.9% of Austria's electricity; the national grid averages 117 gCO₂/kWh (83.6% low-carbon) (2025).

In context: how this plant compares
At 140 MW, Leopoldau power station is around the median gas plant in Austria (153 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). 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 48.3°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.
