Yonki Toe of Dam is a 18 MW hydro power plant in Eastern Highlands, Papua New Guinea. It is operated by PNG Power Limited. Based on its capacity (estimated), it can supply roughly 18,020 homes (estimated). It ranks #8 of 15 Papua New Guinea power plants by installed capacity. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 21.1% of Papua New Guinea's electricity; the national grid averages 514 gCO₂/kWh (23.7% low-carbon) (2024).

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a tropical rainforest climate (Köppen Af) — Southern Hemisphere, latitude 6.2°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.
