Bolgiano power station

Gas power plant in Milan, Italy. Approximate location 45.41634, 9.28332.

GasMilanItalyCCGT · HRSGCO₂ measured

Bolgiano power station is a 62 MW gas power plant in Milan, Italy. It is operated by Eni SpA [100%]. Based on its capacity (estimated), it can supply roughly 70k homes (estimated). It ranks #197 of 489 Italy power plants by installed capacity. Commissioned in 2015, it is around 11 years old — relatively modern. Its annual emissions of 118,706 t CO₂/yr (EU ETS verified (EUTL 2023)) are equivalent to about 28k 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 62 MW, Bolgiano power station is below the median gas plant in Italy (324 MW). Technically it is described as CCGT; combined-cycle with a heat-recovery steam generator (HRSG). 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.

118,706 t CO₂/yr — in everyday terms

This facility's annual emissions are roughly equivalent to:

28kpassenger cars driven for a year
15khomes' yearly energy use
2.0 milliontree seedlings grown 10 years to absorb it

Equivalencies via US EPA Greenhouse Gas Equivalencies; emissions per EU ETS verified (EUTL 2023) (measured for US EPA/EU ETS, modelled for Climate TRACE).

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 humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 45.4°N — which shapes how much energy it can produce and how its output varies through the year.

~27°Ctypical warm-season mean

Site climate & environmental severity

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 moderately corrosive environment (estimated ISO 9223 class C3 — Medium), 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.
