Broad Street Substation Upgrade Plans Available for Review

Seattle City Light is making improvements to the Broad Street Substation to increase the reliability of the regional transmission grid. City Light has developed a preliminary design for the improvements and will be holding an open house to present the design.

The design includes a proposal to vacate a small portion of the permanently closed Broad Street and Seattle requires public benefits in exchange for the loss of use of the public right-of-way. City Light will ask participants for feedback on a proposed set of public benefits.

The open house will be held from 5:30 to 7:30 p.m. on Nov. 8, 2017, at the following location:

Project background: Broad Street Substation system improvements are necessary to meet energy demands of Seattle and our growing region, and to reduce the likelihood of widespread power outages.  Working in conjunction with similar equipment being installed at the Denny Substation, the Broad Street Substation will more reliably deliver power to customers. The new equipment at the Broad Street Substation will include inductors, capacitors and gas insulated switchgear. This combination of equipment will help reduce power outages by controlling and balancing the electrical load that travels through the regional grid.

Seattle City Light is the 10th largest public electric utility in the United States. It has some of the lowest cost customer rates of any urban utility, providing reliable, renewable and environmentally responsible power to about 750,000 Seattle area residents. City Light has been greenhouse gas neutral since 2005, the first electric utility in the nation to achieve that distinction.

Power Restored After Fire at Broad Street Substation

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.
