NUUANU, OAHU (HawaiiNewsNow) - Hawaiian Electric Company crews are working to fix a blackout in Nuuanu.
Roughly 625 customers are in the dark Monday after power was lost around 5:20 p.m.
HECO estimates power should be restored around 11:30 p.m.
It's unclear what caused the outage.
Earlier in the day, a separate outage left over 4,000 people in urban Honolulu without electricity.
That outage was caused by a tree branch falling onto power lines. All affected customers have since gotten power back.
