Power was out for about an hour and a half for 1,200 Alaska Electric Light & Power Co. customers in Auke Bay Monday morning.
At 9:25 a.m., three feeders at the company’s Auke Bay substation opened after a protective device went into alarm, causing the outage, spokeswoman Debbie Driscoll said in an email. To prevent damage, the device cut power to the equipment it protects at the substation by opening the feeders. Engineers are “still researching what caused the protective device to go into alarm,” Driscoll said.
“To get power restored as quickly as possible, we rerouted power and were able to pick up and restore all 1,200 customers by 10:58,” she said.
The first feeder was restored at 9:55 a.m., the second at 10:06 a.m. and the third at 10:58 a.m. All three Auke Bay feeders have since been brought back online and power is no longer being rerouted, she said.
