The Hilo International Airport lost power for about 90 minutes Sunday, causing headaches for weekend travelers.
Power was lost at 11:17 a.m., according to the airport’s security office, and was restored at about 12:45 p.m.
Back-up generators failed after being online briefly, said Dennis Kawakami, airport security supervisor. It’s unclear what caused them to fail.
Airport managers didn’t respond to a request for comment.
Doug Arnott, who was flying to Honolulu, said Hawaiian Airlines was handwriting boarding passes and the Transportation Security Administration was not allowing people through.
Arnott said his flight was being delayed. He had a layover at 3 p.m., and believed he could still make it.
“We got a connecting flight but I’m sure a lot of other people with these giant bags absolutely got to go,” he said.
Kawakami said there was one flight scheduled during the outage.
“Sunday is usually a light day,” he said.
The Hawaii Electric Light Co. experienced a three-minute power outage that would have affected the airport at 10:50 a.m., said Curt Beck, HELCO energy services department manager.
But the airport failed to reconnect back into the grid, causing the longer outage, he said.
“They could not close back into the circuit so they did suffer an additional outage,” Beck said.
The initial power loss was caused by a drop in power generation, he said.
