Cassano Spinola power station is a 50 MW gas power plant in Alessandria, Italy. It is operated by Roquette Italia SpA [100%]. Based on its capacity (estimated), it can supply roughly 56k homes (estimated). It ranks #209 of 489 Italy power plants by installed capacity. Commissioned in 2003, it is around 23 years old — relatively modern. Its annual emissions of 175,845 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 41k 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 50 MW, Cassano Spinola power station is below the median gas plant in Italy (324 MW). Technically it is described as OCGT. 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.

Climate zone & how it works
This gas plant burns natural gas in a turbine — often in a combined-cycle setup — to generate electricity. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 44.8°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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), 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.
