Project overview

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.

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.
