Hydro power plant in Alto Parana, Paraguay. Approximate location -25.4591, -54.6289.
HydroAlto ParanaParaguay
Acaray Dam is a 210 MW hydro power station in Alto Parana, Paraguay. Based on its capacity (estimated), it can supply roughly 210,240 homes (estimated). It ranks #3 of 3 Paraguay power plants by installed capacity. Commissioned in 1981, it is around 45 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 99.5% of Paraguay's electricity; the national grid averages 25 gCO₂/kWh (100.0% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a humid subtropical climate (Köppen Cfa) — Southern Hemisphere, latitude 25.5°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 95% 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: 15/100 — this site sits in the bottom 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.
