Nyabarongo I is a 28 MW hydro power plant in Southern Province, Rwanda. It is operated by Rwanda Energy Group Limited (REG) Government of Rwanda. Based on its capacity (estimated), it can supply roughly 28,032 homes (estimated). It ranks #3 of 11 Rwanda power plants by installed capacity. Commissioned in 2014, it is around 12 years old — relatively modern. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 46.0% of Rwanda's electricity; the national grid averages 354 gCO₂/kWh (49.6% low-carbon) (2024).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a temperate oceanic climate (Köppen Cfb) — Southern Hemisphere, latitude 2.0°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 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.
