Mussalo power station is a 80 MW coal power plant in , Finland. It is operated by Pohjolan Voima Oyj [100%]. Based on its capacity (estimated), it can supply roughly 100k homes (estimated). It ranks #53 of 203 Finland power plants by installed capacity. Commissioned in 1966, it is around 60 years old — an older, legacy facility. In context, coal supplies about 0.2% of Finland's electricity; the national grid averages 57 gCO₂/kWh (96.3% low-carbon) (2025).

At 80 MW, Mussalo power station is below the median coal plant in Finland (230 MW). 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.

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 60.4°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 #11 largest coal power plant of 13 in Finland by capacity.
Finland has 13 coal power plants in this dataset, together about 4,217 MW of capacity.
