Kapaia Power Station is a 39 MW other power plant in Hawaii, United States of America. It is operated by Kauai Island Utility Cooperative. Based on reported annual generation of 174 GWh, it can supply roughly 49,800 homes. It ranks #3039 of 9,833 United States of America power plants by installed capacity. Commissioned in 2002, it is around 24 years old — relatively modern. Its measured emissions of 25,680 t CO₂/yr (Climate TRACE) are equivalent to about 5,986 cars driven for a year. In context, the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This other plant generates electricity for the grid. It sits in a tropical savanna climate (Köppen As) — Northern Hemisphere, latitude 22.0°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.
