Puget Sound Energy transmission line project
Lake Hills-Phantom Lake 115 kV transmission line
- Crews from Potelco and Brent Woodward, Inc. (BWI) began pole and wire installation for the new transmission line on May 5, 2020. This work is expected to last until the end of July 2020.
- General work hours: Mon-Fri: 7 a.m. to 6 p.m. | Sat: 8 a.m. to 6 p.m. | Sat: 9 a.m. to 6 p.m.
- Work hours may vary from the general work hours in certain locations, but all work will be conducted within our permitted work hours.
- Crews from Asplundh Tree Services finished removing the majority of vegetation along the project route in late April 2020. Pole and wire installation is the second of three phases of project construction. Further vegetation removal may be required on a case by case basis as construction continues into Phase 2:
- Phase 1: Vegetation removal (Winter/Spring 2020)
- Phase 2: Pole and wire installation (Spring/Summer2020)
- Phase 3: Landscaping and restoration (Fall 2020)
For more information on construction activities, please view our construction notice.
|Spring & Summer:||Pole and wire installation|
|Fall||Landscaping and site restoration (see drawings)|
The electric system serving the Lake Hills neighborhood of Bellevue has limited reliability, increasing the possibility of outages for customers. PSE's Lake Hills and Phantom Lake substations are served radially, which means they are each served by one transmission line.
If the one transmission line serving a substation goes out, the substation and the customers served by that substation lose power.
To help solve these problems, PSE plans to build a new transmission line between the Lake Hills and Phantom Lake substations. The new transmission line will create a "loop", which means each substation will be connected to two transmission lines. If one line goes out, the other line will still feed the substation and provide power to customers. This project will increase overall system reliability and allow for better use of existing facilities for customers in the Lake Hills neighborhood.
PSE has selected a route corridor along NE 8th St, 148th Ave SE, ending at SE 16th St.
The City of Bellevue is planning a future public improvement project along SE 16th St. PSE plans to postpone construction of the segment of line along SE 16th St so we can collaborate with the city on design and construction for their project and ours. We believe this plan allows us to minimize construction impacts to neighbors along SE 16th St, as they will be limited to one construction timeframe rather than two. The timeline for the city’s project is not yet determined.
