TOR DI VALLE — Italy

TOR DI VALLE is a 223 MW gas power station in Latium, Italy. It is operated by GDF Suez. Based on its capacity (estimated), it can supply roughly 251k homes (estimated). It ranks #104 of 489 Italy power plants by installed capacity. Its annual emissions of 50,707 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 12k cars driven for a year. In context, gas supplies about 47.2% of Italy's electricity; the national grid averages 285 gCO₂/kWh (48.8% low-carbon) (2025).

In context: how this plant compares

At 223 MW, TOR DI VALLE is below the median gas plant in Italy (324 MW). Gas plants burn natural gas either in open-cycle turbines for fast peaking, or in combined-cycle units that recover exhaust heat in an HRSG to reach roughly 55–62% efficiency — the cleanest-burning fossil option.

Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context

This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 41.8°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 37% 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: 35/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

A gas turbine here also runs ~0% below its ISO (15°C) rating at this annual mean (typical CCGT curve, estimate).

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 marine 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.
