The Hawaiian Electric Company says its crews responded to a power outage in Mililani that started Wednesday morning shortly after midnight.
Approximately 900 customers lost power when a utility pole came down on Waimakua Drive.
Hawaiian Electric crews restored power to nearly all customers by 2 a.m. Power was restored to the rest of the customers affected at around 10:20 a.m.
Hawaiian Electric is continuing to investigate what caused the pole to fall.
HECO thanks its customers for their patience and apologizes for the inconvenience.
