Sulcis power station

Coal power plant in Sardinia, Italy. Approximate location 39.1961, 8.4002.

CoalSardiniaItalysubcriticalCO₂ measured

Sulcis power station is a 590 MW coal power station in Sardinia, Italy. It is operated by Enel SpA. Based on reported annual generation of 1,032 GWh, it can supply roughly 295k homes. It ranks #61 of 489 Italy power plants by installed capacity. Commissioned in 1997, it is around 29 years old — long-established. Its annual emissions of 1,239,365 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 289k cars driven for a year. In context, coal supplies about 1.4% of Italy's electricity; the national grid averages 285 gCO₂/kWh (48.8% low-carbon) (2025).

Capacity provenance

The public capacity above is the current source-record value. A 2026 tracker candidate lists 590 MW for Sulcis power station, but it is not used as the public primary value until scope is verified (unit vs operating vs installed/project total).

Capacity claim grade: A3_MAJOR_REVIEW_SCOPE_STATUS - recommended action: manual_scope_status_check - confidence: low_until_scope_verified. This follows a claim-based data model: value + scope + source + confidence, rather than silently overwriting records.

Data provenance

The capacity and/or fuel fields on this page include a source-backed provenance label from GEM, an official registry, Wikidata, OSM, or a cross-source match.

In context: how this plant compares

At 590 MW, Sulcis 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.

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 39.2°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 61% 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: 26/100 — 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

For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in an aggressive, high-corrosion environment (estimated ISO 9223 class C5 — Very high), with marine salt corrosion the leading environmental stress.

Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.

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.
