Seattle City Light crews plan to increase the electrical reliability of the South Lake Union neighborhood by installing an underground electrical vault near the intersection of Republican Street and Fairview Avenue North. This new infrastructure will provide the additional capacity needed for electrical lines coming from the Denny Substation.
Seattle City Light has made great strides in upgrading the electrical reliability of Pioneer Square and improving the looks of Occidental Avenue Alley. City Light crews excavated and replaced aging underground duct banks in the alley just east of Occidental Park earlier this year. In June, a contractor helped the project reach a milestone by restoring the alley with Pioneer Square Preservation Board-approved brick. When complete, the project will not only help increase the reliability and capacity of Pioneer Square; but also, the downtown electrical system.
Starting in early July 2019, Seattle City Light crews will replace aging electrical infrastructure in the Beacon Hill area. Crews will replace aging utility poles, overhead wire and equipment to help upgrade the existing electrical system.
Starting this May, Seattle City Light crews will complete the final trench work on 1st Avenue South, between South Royal Brougham Way and Railroad Way South. Civil construction crews will be installing a new electrical duct bank, which will upgrade aging electrical infrastructure in the SODO and Pioneer Square areas.
Beginning in April 2019, Seattle City Light will replace the aging streetlights in the Shelby-Hamlin neighborhood with a new, more reliable light-emitting diode (LED) streetlight system. The new LED streetlights will make residential streets safer by increasing their visibility at night.
Seattle City Light is continuing to improve customer safety, reduce carbon emissions and conserve resources by converting the globe streetlights in the downtown Seattle core from high-pressure sodium (HPS) lights to energy-efficient LEDs. The new LED lights will enrich the quality of lighting, improve pedestrian and traffic safety, and maintain the character of downtown Seattle’s historic neighborhoods.
In late 2018, Seattle City Light completed its ninth consecutive year conducting contact voltage testing. With the help of Power Survey Company, City Light was able to identify and repair 17 instances, 10 City Light-owned and 7 privately-owned systems, where metal structures or equipment were improperly energized with at least 30 volts of electricity. These instances were responded to and repaired immediately after being discovered.
