Hydro power plant in Valparaiso, Chile. Approximate location -34.0409, -71.5902.
HydroValparaisoChile
RAPEL is a 378 MW hydro power station in Valparaiso, Chile. It is operated by ENDESA. Based on its capacity (estimated), it can supply roughly 378,432 homes (estimated). It ranks #14 of 315 Chile power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 22.2% of Chile's electricity; the national grid averages 289 gCO₂/kWh (66.4% low-carbon) (2025).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Southern Hemisphere, latitude 34.0°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 56% 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: 27/100 — 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.
