Puget Sound Energy substation project

Juanita substation

Summer 2010 project completion
  • Construction of the new Juanita substation was completed in August 2010
  • PSE has completed landscaping around the substation, and will continue to monitor the health of the vegetation and replace plants as necessary
Project overview

In an effort to increase reliability and meet growing demand for power in the Juanita, Totem Lake and Kingsgate areas of Kirkland, Puget Sound Energy rebuilt the Juanita substation. The new substation doubles the capacity of the old substation. Due to the existing utility corridor's configuration and design constraints, PSE shifted the location of the new substation from the southern end to the northern section of the corridor. The substation is located at 10910 NE 132nd St. in Kirkland.

What is a substation?

Substations are critical links in the electricity distribution system, containing utility circuit protection, voltage regulation, and equipment that steps down higher voltage to lower voltage. Before reaching homes and businesses, power is routed through our transmission system to a substation where it is changed to a lower voltage that can be utilized by customers.
