Inkoo power station is a 1,000 MW coal power station in Uusimaa, Finland. It is operated by Fortum Oyj [100%]. Based on its capacity (estimated), it can supply roughly 1.3 million homes (estimated). It ranks #3 of 203 Finland power plants by installed capacity. Commissioned in 1974, it is around 52 years old — an older, legacy facility. Its annual emissions of 63,026 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 15k cars driven for a year. In context, coal supplies about 0.2% of Finland's electricity; the national grid averages 57 gCO₂/kWh (96.3% low-carbon) (2025).

In context: how this plant compares
At 1,000 MW, Inkoo power station is well above the median coal plant in Finland (230 MW). 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.

Climate zone & how it works
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 60.0°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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), 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.
