Puget Sound Energy transmission line project
Sammamish – Juanita 115 kV transmission line
Winter 2015 project updates
Customer power usage is straining the electric system serving Redmond and Kirkland, which reduces PSE's ability to reliably serve power to area residents and businesses. To increase electric system capacity and improve reliability for customers, PSE plans to construct approximately 4.5 miles of 115 kilovolt (kV) transmission line from the Sammamish substation to just south of the existing Juanita substation to interconnect with an existing transmission line that crosses over Northeast 124th Street.

What is a transmission line?
Transmission lines are key elements in the electrical distribution system. These lines safely transport high voltage electricity from power generation sources like dams and wind generating facilities to substations in local communities. Transmission normally takes place at voltages of 55 kV and higher.
Committed to keeping you informed
PSE will continue to provide updates to the community. We will notify residents and businesses near the project area when construction will occur. We aim to complete the work with as little disruption as possible.
