NUOVA LAGO is a 11 MW geothermal power plant in Tuscany, Italy. Based on its capacity (estimated), it can supply roughly 20,648 homes (estimated). It ranks #268 of 441 Italy power plants by installed capacity. Commissioned in 2002, it is around 24 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, geothermal supplies about 2.1% of Italy's electricity; the national grid averages 285 gCO₂/kWh (48.8% low-carbon) (2025).

This geothermal plant taps underground heat to raise steam that drives a turbine. It sits in a hot-summer Mediterranean climate (Köppen Csa) — Northern Hemisphere, latitude 43.3°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 18% 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.
