Plomin Thermal Power Plant Croatia is a 330 MW coal power station in Istarska, Croatia. It is operated by Hrvatska elektroprivreda dd. Based on its capacity (estimated), it can supply roughly 413k homes (estimated). It ranks #6 of 28 Croatia power plants by installed capacity. Commissioned in 1969, it is around 57 years old — an older, legacy facility. Its annual emissions of 1,118,156 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 261k cars driven for a year. In context, coal supplies about 5.0% of Croatia's electricity; the national grid averages 158 gCO₂/kWh (76.3% low-carbon) (2025).

In context: how this plant compares
Technically it is described as subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 45.1°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 14% below 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: 45/100 — this site sits in the mid 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 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.
