Winslow Tap transmission rebuild

Project updates

  • We continue to work on design and construction planning for the Winslow Tap rebuild project, which will replace aging infrastructure and improve safety and access so we can continue to serve customers reliably into the future.
  • Design and permitting will occur through 2026. Construction on the Winslow Tap Rebuild is scheduled for 2027.
  • We have done our best to identify opportunities to minimize project impacts. Where impacts are unavoidable, PSE is required to provide compensatory mitigation. When considering options for mitigation, we identified an opportunity to work with a respected local community organization with extensive experience in science-based conservation — the Bainbridge Island Land Trust.

Project overview

PSE plans to rebuild the existing 4.5 mile Winslow Tap transmission line. The Winslow Tap is the only transmission line serving the Winslow substation, which supplies power to 3,500 homes and businesses on the south end of the island.

The transmission line was built in 1960 and some of its equipment is nearing the end of its useful life and needs to be replaced. In addition, the line is in a heavily-vegetated corridor with difficult terrain, which makes outage response challenging.

We plan to rebuild the aging infrastructure by replacing the poles and equipment and installing new conductor (wire). We’ll also improve safety and access along the existing corridor so we can continue to serve customers reliably well into the future. For more information, review our project fact sheet.
