A widespread power outage occurred in Juneau on Tuesday at 11 a.m. due to a hydropower failure.
Alaska Electric Light & Power (AEL&P) activated diesel backup generation about an hour later and restored regular hydropower by 2 p.m.
According to Debbie Driscoll, vice president of AEL&P, the outage happened 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 noted that staff patrolled the area but couldn't identify the cause, and the transmission line wasn't damaged.
Driscoll stated that other recent power disruptions are unrelated to Tuesday's outage, including a string of outages in North Douglas caused by a squirrel, a tree, and an equipment issue.
