In context: how this plant compares
At 76 MW, Porvoo 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.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Climate zone & how it works
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 60.3°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.
How it compares & nearby plants
The #7 largest oil power plant of 17 in Finland by capacity.
Finland has 17 oil power plants in this dataset, together about 1,442 MW of capacity.
