A fault in the power line from the Swan Lake Hydroelectric Dam triggered Wednesday’s systemwide power outage, according to Andy Donato of Ketchikan Public Utilities Electric Division.
At deadline, the cause of the fault was still under investigation, but Donato guessed it was the result of a landslide or a tree falling into the line.
The late-morning power outage was relatively brief, lasting around 30 minutes for most KPU customers.
