Hydro power plant in Huancavelica, Peru. Approximate location -12.4644, -74.7865.
HydroHuancavelicaPeru
Antunez de Mayolo (Mantaro) is a 798 MW hydro power station in Huancavelica, Peru. It is operated by Electroperú S. A.. Based on reported annual generation of 5,441 GWh, it can supply roughly 1,554,571 homes. It ranks #2 of 32 Peru power plants by installed capacity. Commissioned in 1978, it is around 48 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 56.1% of Peru's electricity; the national grid averages 238 gCO₂/kWh (63.6% 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 12.5°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 32% above 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: 69/100 — this site sits in the top 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.
