A power outage occurred in Juneau on Tuesday at 11 a.m. due to an issue with hydropower.
Alaska Electric Light & Power (AEL&P) switched to diesel back-up generation about an hour later and restored regular hydropower by 2 p.m.
According to Debbie Driscoll, vice president of AEL&P, the outage occurred on a transmission line south of the city, between the west terminal near Taku Inlet and the Thane substation.
It's possible, when we've had situations like that, that a tree branch comes into contact with the line and clears or wildlife comes in contact with the line and clears the line.
Driscoll stated that staff patrolled the area but couldn't identify the cause, and the transmission line wasn't damaged.
Other recent power disruptions in North Douglas, caused by a squirrel, a tree, and an equipment issue, are unrelated to Tuesday's outage.
