Biomass power plant in North Karelia, Finland. Approximate location 62.9167, 30.25.

BiomassNorth KareliaFinlandCO₂ measured

Uimaharju 2 + 1 vp/lv is a 105 MW biomass power station in North Karelia, Finland. It is operated by Enocell Oy. Based on its capacity (estimated), it can supply roughly 145k homes (estimated). It ranks #41 of 203 Finland power plants by installed capacity. Its annual emissions of 1,500 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 350 cars driven for a year. In context, biomass supplies about 12.6% of Finland's electricity; the national grid averages 57 gCO₂/kWh (96.3% low-carbon) (2025).

Data provenance

The capacity and fuel fields on this page are source-record values from the upstream open dataset. They are useful for identification and ranking, but they have not been upgraded to a 2026 registry/GEM-location verified value.

In context: how this plant compares

At 105 MW, Uimaharju 2 + 1 vp/lv is well above the median biomass plant in Finland (39 MW). Biomass plants burn organic material such as wood, residues or waste-derived fuel to raise steam; they are dispatchable and counted as low-carbon where the feedstock is sustainably sourced.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

1,500 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

350passenger cars driven for a year
196homes' yearly energy use
25ktree 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).

Local climate & thermal context

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a subarctic (boreal) climate (Köppen Dfc) — Northern Hemisphere, latitude 62.9°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 137% 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: 98/100 — 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

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.
