The work included installation of underground conduits, vaults, and equipment in order to replace outdated 4kV electrical equipment with updated 26kV infrastructure throughout Webster Point.
Last month, Seattle City Light completed the infrastructure phase of the reliability and capacity upgrade in Webster Point and sent this final information:
City Light Completes Infrastructure Investment at Webster Point
Seattle City Light and its contractor have completed a major milestone in the utility’s plans to improve the capacity, technology, and reliability of the electrical system in the Webster Point neighborhood of Laurelhurst.
KC Equipment has recently completed the installation of underground conduits, vaults, and equipment in order to replace outdated 4kV (4,000 volt) electrical equipment with updated 26kV (26,000 volt) infrastructure. Sidewalks, driveways, planting strips, and street panels affected by the work have been restored. A map showing the construction area and representative during and after photos are shown below.
The current 4kV cable is buried directly in the ground. The high capacity 26 kV cable will be protected by the installed conduit and vaults for greater reliability. The new 26kV electrical system will also have more switching points resulting in shorter outages with fewer customers affected when maintenance is required.
The higher-capacity 26kV cable will be pulled in at a later date. Seattle City Light appreciates the patience of its customers during the successful completion of this important part of the project.
