HONOLULU (AP) — Large parts of Oahu briefly lost power when a generating station operated by an independent power producer unexpectedly shut down.
Hawaiian Electric Co. spokesman Darren Pai said Tuesday a station operated by AES Corp. at Campbell Industrial Park was providing about 23 percent of Oahu's power when it shut down at 10:30 a.m.
The utility automatically suspended electricity delivery to 75,000 customers in parts of central, windward and west Oahu to prevent a demand and supply imbalance from damaging the grid.
Hawaiian Electric says it restored service to most customers shortly after 11 a.m. A small section of Kailua's Enchanted Lake neighborhood regained power after 12 p.m.
Hawaiian Electric is investigating the cause of the AES service outage.
