Połaniec Zielony Blok — Poland

Połaniec Zielony Blok is a 205 MW biomass power station in Subcarpathian Voivodeship, Poland. It is operated by Enea Połaniec S.A.. Based on reported annual generation of 1,292 GWh, it can supply roughly 369k homes. It ranks #67 of 246 Poland power plants by installed capacity. Commissioned in 2012, it is around 14 years old — relatively modern. In context, biomass supplies about 4.9% of Poland's electricity; the national grid averages 589 gCO₂/kWh (31.5% low-carbon) (2025).

Data provenance

Capacity and fuel are the upstream open-dataset record, not yet matched to a 2026 registry or GEM entry.

capacity: WRI GPPD; fuel: WRI GPPD

In context: how this plant compares

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 50.4°N — which shapes how much energy it can produce and how its output varies through the year.

Monthly mean temperature

Heating degree-days here run 43% 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: 76/100 — 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 mild atmospheric environment (estimated ISO 9223 class C2 — Low), 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.
