26th largest plant in Hawaii · 4073rd nationally
Kahului is a oil power plant in Hawaii with a nameplate capacity of 34.0 MW. It generates roughly 140.0k MWh per year — enough to power about 13,332 average U.S. homes.
Its capacity factor of 47% puts it in the middle range — running steadily but not full-time. At 2441 lb CO₂/MWh, its emission rate sits above the national grid average of roughly 800 lb/MWh.
Ghost bars are each month's theoretical maximum (34.0 MW nameplate × hours in the month). Filled bars are actual net generation reported to EIA Form 923. The gap between them is capacity factor made visible.

Annual totals and CO₂ rate reported by EPA eGRID for 2023. Reference averages are approximate U.S.-wide figures from the same dataset.
Oil-fired plants typically run only during peak demand or grid emergencies because oil is expensive compared to gas and coal. They have the highest CO₂ emissions per MWh of any common generation technology.
