Puget Sound Energy transmission line project
Energize Eastside
Energize Eastside is now energized. We completed construction on Energize Eastside and energized the new 230 kV transmission lines in north Bellevue and Redmond in December 2024. In fall 2023, we energized the new Richards Creek substation and the new 230 kV transmission lines from Renton to south Bellevue.
Now, Energize Eastside is providing additional system capacity to Eastside customers to keep the lights on for years to come. Thank you for your patience during construction and restoration!
Project overview
Energize Eastside includes the new Richards Creek substation in Bellevue and upgrades approximately 16 miles of transmission poles and lines from 115 kV to 230 kV within an existing corridor from Renton to Redmond. The project is needed to comply with mandatory federal transmission planning requirements and support growth in King County. As the backbone of the Eastside’s transmission system, Energize Eastside upgrades the electric infrastructure built in the 1960s.
