Hydro power plant in Rondonia, Brazil. Approximate location -8.8011, -63.9497.
HydroRondoniaBrazil
Santo Antônio is a 3,568 MW hydro power station in Rondonia, Brazil. It is operated by Santo Antônio Energia (Madeira Energia / Furnas-led). Based on its capacity (estimated), it can supply roughly 3,572,077 homes (estimated). It ranks #4 of 2,549 Brazil power plants by installed capacity. Commissioned in 2012, it is around 14 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 51.8% of Brazil's electricity; the national grid averages 110 gCO₂/kWh (88.7% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a tropical monsoon climate (Köppen Am) — Southern Hemisphere, latitude 8.8°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 100% 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: 13/100 — 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.
