Hydro power plant in Santa Rosa, Guatemala. Approximate location 14.29, -90.505.

HydroSanta RosaGuatemala

Aguacapa is a 90 MW hydro power plant in Santa Rosa, Guatemala. Based on reported annual generation of 268 GWh, it can supply roughly 76,714 homes. It ranks #10 of 76 Guatemala power plants by installed capacity. Commissioned in 1982, it is around 44 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 39.9% of Guatemala's electricity; the national grid averages 301 gCO₂/kWh (68.3% low-carbon) (2024).

Local climate & thermal context

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a tropical savanna climate (Köppen Aw) — Northern Hemisphere, latitude 14.3°N — which shapes how much energy it can produce and how its output varies through the year.

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.
