HECO: Loss of power generator causes brief Oahu outages

HONOLULU (HawaiiNewsNow) -

Hawaiian Electric says that the unexpected loss of of the largest generating unit on the island, an independent power plant operated by AES, required Hawaiian Electric to briefly shut off power to  customers in different sections of the island at around 11:23 a.m. 

The outages affected customers in areas across the island, including Waialua, Kahuku, Waihee, Kaneohe, the Kapiolani area, downtown Honolulu, Waiakamilo, Moanalua, Halawa, Moanalua, and Waipahu.

Power to most affected customers was restored shortly before 12 p.m..

The outage occurred after a 180-megawatt power plant operated by AES, an independent power producer, unexpectedly went out of service.

HECO says the targeted emergency outages were necessary to avoid a more widespread outage or damage to the electric system from an imbalance of too much demand versus too little available generation. 

“We apologize for this disruption and thank our customers for their patience. We understand any kind of an outage is disruption and we are working with AES to investigate this issue and bring their generator back into service,” said Darren Pai, Hawaiian Electric spokesperson.

An estimated 57,000 customers were affected by the outages.
