Forssa kt is a 320 MW oil power station in Haeme, Finland. It is operated by Fingrid Oyj. Based on reported annual generation of 2 GWh, it can supply roughly 600 homes. It ranks #9 of 203 Finland power plants by installed capacity. Commissioned in 2013, it is around 13 years old — relatively modern. Its annual emissions of 4,894 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 1.1k cars driven for a year. In context, oil supplies about 2.3% of Finland's electricity; the national grid averages 57 gCO₂/kWh (96.3% low-carbon) (2025).

In context: how this plant compares
At 320 MW, Forssa kt is well above the median oil plant in Finland (52 MW). Technically it is described as OCGT. Oil-fired plants burn heavy fuel oil or diesel, usually as peaking or backup capacity on islands and grids without gas pipelines; high fuel cost keeps their utilisation low.

Local climate & thermal context
This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a warm-summer humid continental climate (Köppen Dfb) — Northern Hemisphere, latitude 60.8°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 103% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 94/100 — this site sits in the top third of the power plants we cover by heating degree-days.
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
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.
