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).

In context: how this plant compares
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.

Climate zone & how it works
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).
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.
