Puget Sound Energy substation project
Langley Tap 115kV transmission line upgrade
...continuation of Maxwelton substation projects
2018 project updates - Langley Tap
- July 2018: Vegetation along the route will be trimmed and/or removed to ensure a safe construction environment.
- September 2018: Replacement of the aging wooden poles is expected to begin.
To increase reliability for our customers on south Whidbey Island, Puget Sound Energy constructed a new 25 megavolt amperes (MVA) substation in 2016.
Several projects remain including:
- Langley 15 feeder extension: Upgrade a section of our existing 115 kilovolt (kV) transmission line.
- Langley Tap: Replace aging poles on an existing transmission line
Langley 15 feeder extension
In spring/summer 2018, we began upgrading the Langley 15 feeder extension, an existing single-phase low-voltage line, to a higher capacity three-phase line along Maxwelton Road south from Craw Road and extending onto French Road. This will provide additional capacity to allow the new substation to back up electric load normally served by Langley substation, and will greatly improve reliability of electrical service in Langley.
After the Langley 15 feeder is upgraded and operational (we anticipate fall 2018), we will replace the aging wooden poles of the Langley Tap, an existing transmission line currently running from the Langley substation, along SR-525, Midvale Road, Maxwelton Road and Craw Road to the new Maxwelton substation. Prior to construction, our vegetation management partner, Asplundh, will trim and remove vegetation as needed for safe construction.
