Huutokoski power station

Oil power plant in Southern Savonia, Finland. Approximate location 62.2116, 27.6756.

OilSouthern SavoniaFinlandOCGTCO₂ measured

Huutokoski power station is a 180 MW oil power station in Southern Savonia, Finland. It is operated by Fingrid Oyj. Based on its capacity (estimated), it can supply roughly 135k homes (estimated). It ranks #19 of 203 Finland power plants by installed capacity. Commissioned in 1971, it is around 55 years old — an older, legacy facility. Its annual emissions of 1,218 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 284 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 180 MW, Huutokoski power station 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.

1,218 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

284passenger cars driven for a year
159homes' yearly energy use
20ktree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; emissions per EU ETS verified (EUTL 2023) (measured for US EPA/EU ETS, modelled for Climate TRACE).

Climate zone & how it works

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 62.2°N — which shapes how much energy it can produce and how its output varies through the year.

Site climate & environmental severity

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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), with thermal cycling 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.
