Crews worked through the night to restore power to approximately 12,900 customers. While crews worked to restore power to an earlier outage, four circuit breakers relayed offline causing a cascading effect and a small substation fire. The sequence of events led to a larger outage. Affected areas in parts of Ballard, Magnolia, and Queen Anne were returned to power by 6:15 a.m. this morning, Saturday, January 20. The cause of the original outage is still being investigated.
