Thousands of Hawaiian Electric customers in Honolulu were left in the dark this morning in multiple power outages.

At 6:28 a.m. 3,735 customers were without power in neighborhoods from Punchbowl to Salt Lake due to five power outages, according to Hawaiian Electric’s Oahu Outage Map.

As of 7:03 a.m., the number of customers without power had been reduced to 845.

A glitch on HECO’s outage map showed 1,162 customers in Kalihi Valley and Moanalua without power in a separate outage as of 7:29 a.m., but they were actually part of the earlier outage, according to HECO spokeswoman Shannon Tangonan.

As of 8:08 a.m., power had been restored to all customers affected by the outages. The cause of the outages is unknown and is under investigation, according to Tangonan.
