Castellanza CHP power station is a 73.6 MW gas power plant in Varese, Italy. It is operated by Metaenergia SpA [100%]. Based on its capacity (estimated), it can supply roughly 83k homes (estimated). It ranks #188 of 489 Italy power plants by installed capacity. Commissioned in 2023, it is around 3 years old — recently built. Its annual emissions of 21,010 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 4.9k 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 73.6 MW, Castellanza CHP power station 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.

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 temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 45.6°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.
