All customers have been restored power Monday evening after a vehicle struck down a pole in Nanakuli.
Hawaiian Electric says it happened a little after 1 p.m. on Mailiilii Road, near Paakea Road.
About 600 customers lost power, and the road was closed following the collision.
Crews spent most of the afternoon working on repairs, and eventually restored service to all customers at 7:10 p.m.
The road was also reopened.
