Biomass power plant in Soedermanland, Sweden. Approximate location 58.743, 17.0006.

BiomassSoedermanlandSweden

Idbaksverket is a 35 MW biomass power plant in Soedermanland, Sweden. It is operated by 100% Vattenfall. Based on its capacity (estimated), it can supply roughly 48k homes (estimated). It ranks #99 of 178 Sweden power plants by installed capacity. Commissioned in 1997, it is around 29 years old — long-established. In context, biomass supplies about 5.8% of Sweden's electricity; the national grid averages 35 gCO₂/kWh (98.8% low-carbon) (2025).

In context: how this plant compares

At 35 MW, Idbaksverket is below the median biomass plant in Sweden (94 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.

Local climate & thermal context

This biomass plant burns organic material (wood, residues) to raise steam for a turbine. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 58.7°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 66% 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: 85/100 — 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 corrosive environment (estimated ISO 9223 class C4 — High), with marine corrosion the leading environmental stress.
