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 construction of a new Twin City Substation to improve service to Stanwood and Camano Island
  • Construction of the Cedar Valley Substation, adjacent to the Lynnwood Transit Center to accommodate expanded Sound Transit light rail service and high-density commercial and residential development.
  • Construction of the Port Gardner Substation on the north Everett waterfront, to meet growing needs as the Port of Everett moves forward on commercial, recreational and residential development plans
  • Upgrade to the East Arlington Switching Station
  • 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 about 600 aging poles during the year. It also will assess and treat more than 10,000 poles. In addition, the utility will replace 30 to 40 miles of underground cable.

Interurban Trail Closure - Lynnwood (click to read)

To accommodate planned growth and redevelopment of the Lynnwood City Center and new light rail service, the PUD is constructing a new Cedar Valley Substation and improving powerlines along the Interurban Trail. To accommodate these projects, the City of Lynnwood will close a section of the Interurban Trail adjacent to the Lynnwood Transit Center.

The closed section runs between 52nd Avenue West and approximately 44th Avenue West (see Cedar Valley Substation document below for map). The City anticipates the section of trail will be closed from September 2018 through mid-March 2019. The exact timing of the trail closure will depend on planning, permitting and final construction schedule.
