GasThe MarchesItaly

JESI is a 140 MW gas power station in The Marches, Italy. It is operated by Edison. Based on its capacity (estimated), it can supply roughly 157,680 homes (estimated). It ranks #105 of 441 Italy power plants by installed capacity. Commissioned in 2001, it is around 25 years old — relatively modern. In context, gas supplies about 47.2% of Italy's electricity; the national grid averages 285 gCO₂/kWh (48.8% low-carbon) (2025).

~220,752 t CO₂/yr (estimated) — in everyday terms

This facility's annual emissions are roughly equivalent to:

51,457passenger cars driven for a year
28,789homes' yearly energy use
3,679,200tree seedlings grown 10 years to absorb it

Estimated, not measured: from installed capacity at a typical 45% load factor × a typical gas emission factor (~400 g CO₂/kWh, IPCC AR5 / US EIA). Actual emissions depend on plant efficiency and running hours.Equivalencies via US EPA Greenhouse Gas Equivalencies.

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 humid subtropical climate (Köppen Cfa) — Northern Hemisphere, latitude 43.6°N — which shapes how much energy it can produce and how its output varies through the year.

Heating degree-days here run 19% 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: 43/100 — this site sits in the mid third of the power plants we cover by heating degree-days.

In colder climates, uninsulated hot equipment (boilers, turbines, valves, steam lines) loses proportionally more heat to ambient air — exactly the loss Inzonex modular insulation is designed to cut.

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