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.
  • Construction of the Swamp Creek Switching Station, located just north of the I-5/I-405 interchange in Lynnwood, to meet system capacity growth in the Lynnwood/Mill Creek area. (See FAQs to the right.)

Poles & Distribution

In 2019, the PUD plans to replace about 500 aging poles as well as assess and treat more than 25,000 poles. In addition, 20 to 30 miles of aging underground cable will be replaced throughout the PUD service area this year.
