Hydro power plant in Rio Negro, Argentina. Approximate location -39.56, -65.6817.
HydroRio NegroArgentina
GUILLERMO CESPEDES is a 5 MW hydro power plant in Rio Negro, Argentina. It is operated by DPA RIO NEGRO. Based on its capacity (estimated), it can supply roughly 5,205 homes (estimated). It ranks #194 of 236 Argentina power plants by installed capacity. Commissioned in 1963, it is around 63 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 39.6°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 39% 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: 34/100 — 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.
