Hinkismäki power station is a 45 MW gas power plant in Kymenlaakso, Finland. It is operated by KSS Energia Oy [100%]. Based on its capacity (estimated), it can supply roughly 51k homes (estimated). It ranks #74 of 203 Finland power plants by installed capacity. Commissioned in 1988, it is around 38 years old — long-established. In context, gas supplies about 1.2% of Finland's electricity; the national grid averages 57 gCO₂/kWh (96.3% low-carbon) (2025).

At 45 MW, Hinkismäki power station is below the median gas plant in Finland (120.6 MW). Technically it is described as OCGT. 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 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 60.9°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).
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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), 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.
The #13 largest gas power plant of 20 in Finland by capacity.
Finland has 20 gas power plants in this dataset, together about 2,246 MW of capacity.
