Seattle City Light explains causes of Queen Anne power outages

Power has been restored to all customers in the Queen Anne and Magnolia neighborhoods. Equipment failure caused outages Saturday and Sunday.

Power has been restored to all customers in the Queen Anne and Magnolia neighborhoods. What we (City Light) know at this point is that a planned repair in an underground vault near the Seattle Center was completed on schedule early Saturday morning. In order to prepare a test of the repair, power for the Center was diverted to an alternate feeder (a feeder is a big line that transmits power to large areas of the city).

At that point, a junction box failed on the alternate feeder. Power was switched to a second alternate feeder in order to identify what repairs needed to be made. On Sunday, we had a failure on this second alternate feeder at another location.

Crews were sent out to isolate the problem and our switching operators were able to restore power to customers using multiple feeders. Meanwhile repairs are ongoing to the original junction box and failed cable.

There is no estimate for completion of the original repairs.
