Gratkorn Mill power station is a 70 MW gas power plant in Styria, Austria. It is operated by Sappi Austria Produktions GmbH & Co KG [100%]. Based on its capacity (estimated), it can supply roughly 79k homes (estimated). It ranks #57 of 131 Austria power plants by installed capacity. Commissioned in 2004, it is around 22 years old — relatively modern. Its annual emissions of 202,975 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 47k 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).

At 70 MW, Gratkorn Mill power station is below 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.

This facility's annual emissions are roughly equivalent to:

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 47.1°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).
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a mild atmospheric environment (estimated ISO 9223 class C2 — Low), with humidity / wetness the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
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.
