Oil power plant in Hawaii, United States of America. Approximate location 20.8969, -156.4627.
OilHawaiiUnited States of AmericaCO₂ reported
Kahului is a 34 MW oil power plant in Hawaii, United States of America. It is operated by Maui Electric Co Ltd. Based on reported annual generation of 163 GWh, it can supply roughly 46,457 homes. It ranks #3167 of 9,833 United States of America power plants by installed capacity. Commissioned in 1956, it is around 70 years old — an older, legacy facility. Its measured emissions of 22,331 t CO₂/yr (Climate TRACE) are equivalent to about 5,205 cars driven for a year. In context, oil supplies about 0.7% of United States of America's electricity; the national grid averages 384 gCO₂/kWh (43.0% low-carbon) (2025).

This oil plant burns oil or diesel to drive turbines or reciprocating engines. It sits in a tropical rainforest climate (Köppen Af) — Northern Hemisphere, latitude 20.9°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.
