Pirris Hydroelectric Power Station Costa Rica is a 134 MW hydro power station in San Jose, Costa Rica. Based on its capacity (estimated), it can supply roughly 134,153 homes (estimated). It ranks #6 of 27 Costa Rica power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 74.8% of Costa Rica's electricity; the national grid averages 24 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 tropical monsoon climate (Köppen Am) — Northern Hemisphere, latitude 9.6°N — 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.
