Fiume Santo power station is a 640 MW coal power station in Sardinia, Italy. It is operated by E.On Produzione SpA. Based on reported annual generation of 3,561 GWh, it can supply roughly 1.0 million homes. It ranks #59 of 489 Italy power plants by installed capacity. Commissioned in 1992, it is around 34 years old — long-established. In context, coal supplies about 1.4% of Italy's electricity; the national grid averages 285 gCO₂/kWh (48.8% low-carbon) (2025).

In context: how this plant compares
At 640 MW, Fiume Santo power station is around the median coal plant in Italy (640 MW). 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.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 40.8°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 48% 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: 30/100 — this site sits in the bottom 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 an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion 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.
