Wailoa is a 160 MW hydro power station in Western, Fiji. It is operated by Fiji Electricity Authority. Based on its capacity (estimated), it can supply roughly 160,182 homes (estimated). It ranks #1 of 12 Fiji power plants by installed capacity. Commissioned in 1983, it is around 43 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 52.2% of Fiji's electricity; the national grid averages 278 gCO₂/kWh (63.5% 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 17.8°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.
