Porto Marghera Refinery power station is a 114 MW oil power station in Veneto, Italy. It is operated by Eni SpA [100%]. Based on its capacity (estimated), it can supply roughly 86k homes (estimated). It ranks #153 of 489 Italy power plants by installed capacity. Commissioned in 1985, it is around 41 years old — long-established. Its modelled annual emissions are 97,217 t CO₂/yr (Climate TRACE), equivalent to about 23k cars driven for a year. In context, oil supplies about 2.6% of Italy's electricity; the national grid averages 285 gCO₂/kWh (48.8% low-carbon) (2025).

The public capacity above is the current source-record value. A 2026 tracker candidate lists 114 MW for Porto Marghera Refinery 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: A2_MEDIUM_REVIEW - recommended action: manual_source_check - confidence: medium. This follows a claim-based data model: value + scope + source + confidence, rather than silently overwriting records.

At 114 MW, Porto Marghera Refinery power station is below the median oil plant in Italy (210 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). Oil-fired plants burn heavy fuel oil or diesel, usually as peaking or backup capacity on islands and grids without gas pipelines; high fuel cost keeps their utilisation low.

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 45.5°N — which shapes how much energy it can produce and how its output varies through the year.
Climate zone & typical temperatures: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid).
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 a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness 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.
