Several outages were reported around Oahu Monday morning, affecting a total of 65,000 homes and businesses.
Hawaiian Electric Co. said the outages were caused by generating station at Campbell Industrial Park that tripped offline at around 9:50 a.m., triggering instability in the system.
HECO officials said the station is owned by AES, an independent company that sells power to HECO, and is the single largest generating unit in the system.
As a result, power was disconnected to several neighborhoods in order to restabilize the grid and prevent a potentially bigger, island-wide outage, HECO said.
Affected neighborhoods include Ewa, Mililani, Wahiawa, Waipahu, Makalapa, Pacific Palisades, Kailua, Kaneohe and Waihee.
The outage forced Tanioka’s Seafood and Catering in Waipahu to scramble to save its raw seafood.
“Even when it’s (a short outage), we have to pull all our poke out and keep it in the back refrigerators,” said manager Justin Tanioka. “If it’s longer, it becomes more worse. For the initial, it’s hard. It stops production in the kitchen.”
Additional generators were brought online to help restore power.
Crews will investigate the problem and take appropriate action, HECO said.
A separate, unrelated outage was also reported in Kaaawa that affected 780 homes and businesses.
All outages were restored at 12:40 p.m.
