EC Kielce — Poland

EC Kielce is a 10 MW biomass power plant in Swietokrzyskie, Poland. It is operated by Polska Grupa Energetyczna SA. Based on its capacity (estimated), it can supply roughly 14k homes (estimated). It ranks #203 of 246 Poland power plants by installed capacity. Commissioned in 2008, it is around 18 years old — relatively modern. Its annual emissions of 168,141 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 39k cars driven for a year. In context, biomass supplies about 4.9% of Poland's electricity; the national grid averages 589 gCO₂/kWh (31.5% low-carbon) (2025).

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.

168,141 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

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 temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 50.9°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 53% 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: 81/100 — 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.
