Seattle City Light is continuing to investigate the cause of the power outage that impacted a large part of Downtown Seattle customers on Wednesday, May 25. Overall, 12,000 meters went out from 11:30 a.m. to 12:30 p.m. on the day of the outage.
The outage occurred at the Massachusetts Substation and Union Substation, which serve Downtown Seattle. Crews were able to restore power to the Massachusetts Substation by approximately 12:10 p.m. and the Union Substation by 12:30 p.m.
More information will be shared once the outage investigation is complete.
A fire at the Broad Street Substation damaged the capacitor bank on the right.
Power has been restored to about 325 customers, including the Seattle Center, the Space Needle, Experience Music Project and the Monorail, that were affected by an outage caused when a fire broke out in Seattle City Light’s Broad Street Substation at 319 6th Ave. N.
The fire occurred at 10:16 a.m. The Seattle Fire Department was quickly on scene to put it out. No one was injured. The oil within the capacitor bank is a non-toxic mineral oil used for insulation.
Power was restored by noon. Repair crews determined the fire began in a capacitor bank, which is a device that regulates the quality of electricity flow.
The cause of the fire is still under investigation.
