Aroskraft power station

Oil power plant in Västmanland, Sweden. Approximate location 59.58849, 16.513861.

OilVästmanlandSwedenSteamCO₂ measured

Aroskraft power station is a 250 MW oil power station in Västmanland, Sweden. It is operated by Mälarenergi AB. Based on its capacity (estimated), it can supply roughly 188k homes (estimated). It ranks #23 of 178 Sweden power plants by installed capacity. Commissioned in 1970, it is around 56 years old — an older, legacy facility. Its annual emissions of 197,419 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 46k cars driven for a year. In context, oil supplies about 1.2% of Sweden's electricity; the national grid averages 35 gCO₂/kWh (98.8% 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 250 MW, Aroskraft power station is around the median oil plant in Sweden (250 MW). Technically it is described as Steam. 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.

197,419 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

46kpassenger cars driven for a year
26khomes' yearly energy use
3.3 milliontree 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 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 59.6°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 74% 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: 87/100 — 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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness 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.
