System Improvements


Over the next several years, the PUD will carry out a series of electrical system improvements and preventative maintenance projects to help ensure the utility maintains high levels of reliability and meets the needs of a growing customer base.

Substation Projects

One of the most significant projects will transform the Beverly Park Substation in South Everett (north of Hwy. 526) into the largest substation in the utility’s service area. Once completed, it will double the footprint of the 115-kilovolt facility, increasing it from seven breakers to 15. It also will include installation of the PUD’s first 230-115-kilovolt transformer. The multi-year project will be completed in 2018. The upgraded facility will improve system reliability, provide reserve capacity in case of a BPA transformer failure and add switching capability to the PUD’s transmission system.

Other large projects include:

  • Design and constructions of Eagle Creek Substation in East Arlington
  • Design and construction of a new Twin City Substation to improve service to Stanwood and Camano Island
  • Upgrade to the East Arlington Switching Station
  • Rebuild of Smokey Point Substation, north of Marysville
  • Rebuild of Cascade Substation, east of Mill Creek
  • Substation Reliability Improvement Project includes upgrades to software, communication protocols and protection and control systems at substations – key follow-up measures related to the utility’s substation automation effort.

Poles & Distribution

The PUD plans to replace 600-700 aging poles during the year. It also will complete a two-year program to assess and treat more than 25,000 poles. In addition, the utility will replace 30 to 40 miles of underground cable. Substation underground feeders also are slated for replacement in several communities including Lynnwood, Mountlake Terrace, Edmonds, Everett and Sultan.
