Hydro power plant in Mendoza, Argentina. Approximate location -34.833, -68.5168.
HydroMendozaArgentina
NIHUIL IV is a 22 MW hydro power plant in Mendoza, Argentina. It is operated by HIDRONIHUIL SA - LIHUEN SA. Based on its capacity (estimated), it can supply roughly 22,425 homes (estimated). It ranks #119 of 236 Argentina power plants by installed capacity. Commissioned in 1965, it is around 61 years old — an older, legacy facility. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 17.1% of Argentina's electricity; the national grid averages 346 gCO₂/kWh (41.6% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a cold semi-arid steppe climate (Köppen BSk) — Southern Hemisphere, latitude 34.8°S — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 17% 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: 44/100 — 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.
