System Improvements

For more than 70 years, the PUD has kept the lights on and power flowing for our customers. Reliability is one of our core values and the work we do every day ensures that we deliver that consistent power.

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

The PUD has more than 100 substations and switching stations across our service area. These substations are critical in delivering power to our customers. As our customer base grows, we must update and upgrade these substations to continue to deliver reliable service. Here’s a look at current substation projects:

  • To increase reliability in Stanwood and Camano Island, the PUD is building a new substation and rebuilding another. The new Twin City Substation (completion 2023) will replace the old North Stanwood Substation, which will be decommissioned in 2025. The PUD also plans to rebuild the North Camano Substation (completion 2025).
  • To better serve new large customer power demands, the PUD is bevaluating locations for a new substation in Everett and upgrading its Edgecomb Substation (completion 2023) and its North Mountain Substation in Darrington (completion 2022).
  • To better serve the growing power demands in north Snohomish County, the PUD is upgrading its Stimson Crossing Substation (completion 2025).
  • To provide reserve capacity in case of a BPA transformer failure and add switching capability, the PUD is building the new Getchell Switching Station (completion 2026) in east Marysville near Highway 9. The PUD is designing this station to allow room for up to two BPA points of delivery for future growth in the north county area.
  • To better serve the eastern portion of its service area, the PUD plans to design and build the new Sky Valley Substation (completion 2024) and upgrade its Clearview Substation (completion 2023).
  • To better serve the Everett portion of its service area, the PUD plans to upgrade its Harbour Pointe Substation (completion 2022) and its Picnic Point Substation (completion 2024).
  • To better serve the southern portion of its service area, the PUD plans to upgrade its Brier Substation (completion 2025), its Thrashers Corner Substation (completion 2025) and its Westgate Substation (completion 2025).

Line Projects

  • The PUD will replace more than 50 distribution poles and install transmission lines to connect circuits from the Woods Creek and Lake Chaplain substations to improve reliability to the PUD’s Jackson Hydroelectric Project powerhouse and City of Everett’s water treatment plant (completion 2022).
  • To help with a road improvement project to improve accessibility for sidewalks, PUD crews will re-locate approximately 60 transmission and distribution poles along 76th Ave. West in Lynnwood and Edmonds (completion 2022).
  • To provide redundancy power to Camano Island, the PUD will build a new Stanwood-to-Camano 115-kV line build (completion 2023).
  • To better serve the growing power demands in northern portion of its service area, the PUD is rebuilding its Stimson-to-Stanwood 115-kV line (completion 2023) and designing and building a new Stimson-to-Sills Corner 115-kV line (completion 2025).
  • To maintain reliable service to Hat Island, the PUD is planning to rebuild the Hat Island underground cable (completion 2023).

Pole and Distribution Maintenance

The PUD annually replaces about 500 aging poles as well as assesses and treats more than 25,000 poles. In addition, 20 to 30 miles of aging underground cables will be replaced throughout the PUD’s service area.
