Snohomish County PUD has moved ahead on a series of electrical system improvements and preventative maintenance projects this year to help ensure the utility maintains the highest levels of reliability for its rapidly growing customer base.
This year, the PUD plans to replace about 700 aging poles. During the 2016-2017 timeframe, the utility will have assessed and treated more than 25,000 poles. In addition, 30 to 40 miles of aging underground cable will be replaced throughout the PUD service area this year.
Work continued this year to upgrade equipment at Everett’s Beverly Park substation, including installation of the utility’s largest transformer. The PUD is working with the Bonneville Power Administration and Puget Sound Energy on the project, aimed at bolstering reliability for customers throughout the region. It also includes reconfiguration of transmission lines and installation of new fiber optic lines.
Construction of the new Eagle Creek Substation in Arlington, in conjunction with upgrades to substations in East Arlington and Oso, will provide additional means of backup power for these communities, which have historically been more susceptible to weather conditions and outages.
Substations in Smokey Point and North Everett are being entirely rebuilt in 2017, while substations in Monroe and Mill Creek/Seattle Hill are being upgraded with new equipment.
In addition, numerous high-voltage poles, lines and related equipment will be reconfigured or receive maintenance during the year.
Meanwhile, the PUD has relocated poles and wires to accommodate development and construction projects, including the City of Everett’s bridge project, linking Grand Avenue Park and West Marine View Drive on the waterfront.
