Seattle City Light will be upgrading the underground electrical system in the Hurstwood neighborhood starting in October. As underground cables age, their protective insulation deteriorates. When a crack forms, and water or dirt reach the wires, it can lead to an unplanned power outage. Seattle City Light is working with a company called Novinium to help avoid such outages by using a silicone injection process to upgrade the cables. The silicone fills the cracks and extends the life of the cable and improves reliability for your electrical service.
Crews will be entering electrical vaults in the neighborhood and testing the cable to determine if the injection process can work. If the cable condition is satisfactory, crews will inject the silicone into the lines. If cables canít be injected, they will be replaced at a later time.
Residents can expect:
-Planned power outages so crews can work safely
-Up to (but no more than) seven planned outages and NOT on consecutive days
-Notification by door hanger the Thursday of the week before the outage
-Outages lasting about eight hours
Work will be begin in late October and last approximately 7 weeks. Work hours are 8:30 a.m. - 4:30 p.m., Monday-Thursday. There will be no work Thanksgiving Day or the Wednesday before.
