[ARCHIVED] Plan Ahead: Puget Sound Energy Electrical Upgrades

PSE electrical upgrade project

Puget Sound Energy’s electric service partner, Potelco, Inc., is at work along a 10-mile stretch of 115 kV transmission lines between PSE’s substations in Issaquah, Redmond and Sammamish.

The project will ensure continued electric reliability and compliance with important industry standards.

Crews will work between the substations at Novelty Hill, 24525 N.E. 102nd St., Redmond; Sahalee, 3578 Sahalee Way N.E., Sammamish; and Lake Tradition, 26000 S.E. 79th St., Issaquah.

Work will be done weekdays between 7 a.m.-5 p.m. and is expected to be complete in September.

Potelco crews will be working primarily along Issaquah-Pine Lake Road, 228th Avenue Southeast, Sahalee Way Northeast and Northeast Union Hill Road. Work will take place in two phases — the first phase of work will begin at Black Nugget Drive and proceed north toward Pine Lake.

Crews will replace some poles as well as rehang wire and reconfigure the electrical equipment on existing poles. Expect to see large utility trucks, materials staging and other machinery along the route.

Brief power outages to surrounding communities along the route may be required in order to safely complete the project. PSE and Potelco will notify residents and businesses in advance of planned outages related to the project. Note: Not all residents will be affected by an outage.

You may experience traffic delays during work hours; signs and flaggers will help direct traffic and pedestrians around the construction zones.

Work hours, schedule and construction activities may vary based on location and inclement weather.
