More than 3,000 Seattle City Light customers in Ballard and surrounding North Seattle neighborhoods lost power Monday, according to utility officials.
The outage began Monday morning and affected customers from the Lake Union area north through Ballard and Discovery Park. Seattle City Light was able to restore service to most customers by early afternoon.
In a statement provided to My Ballard, Seattle City Light said the outage was caused by the failure of a lightning arrestor, a protective device installed in the utility’s distribution system to protect equipment from dangerous overvoltage conditions caused by lightning strikes.
The utility said crews were dispatched to diagnose and repair the problem. Before repairs were completed, Seattle City Light restored power to all affected customers by rerouting electricity through other parts of its system.
The outage came during unusually hot weather across the Seattle area, with temperatures reaching record levels for the year.
