Project Overview
The Westside Upgrade Project will improve grid reliability by increasing the capacity and efficiency of a critical transmission pathway. These upgrades are necessary to accommodate changing energy patterns and stabilize the regional electric grid as more renewable energy flows north from California. When complete, the project will deliver more reliable electricity to PGE customers both today and into the future.
Upgrades include:
- Rewires approximately 15 miles of 230-kilovolt (kV) transmission line with advanced conductor for more capacity
- Modifies or replaces existing poles and towers, and installs new poles where needed, to accommodate the heavier advanced conductor for improved resilience
- Bifurcates 5 miles of 230-k V transmission line for increased efficiency
- Upgrades PGE’s Sherwood, Murrayhill and St Marys substations in southeast Washington County for enhanced reliability
All construction will take place within existing easements, ROW or on PGE property. Some activities may temporarily impact surrounding communities, including traffic disruptions. As the project progresses, PGE and our contractors will share updates to keep customers informed.
Timeline
Project Start
In-Service
McLoughlin - Pearl - Sherwood
Murrayhill - Sherwood
St Marys - Murrayhill
Timeline is approximate and subject to change.
Before & After
See realistic before-and-after photo simulations at specific project locations. Final design may change pending engineering and permit review.
Transmission Structures
Existing poles and towers will be replaced or modified, and new structures will be added to accommodate the heavier advanced conductor. Structure heights may increase up to 15′ for proper ground and vegetation clearance.
Construction Updates
- Construction is nearly complete on the McLoughlin – Pearl – Sherwood segment. Permitting is underway for the final mile, south of SW Tonquin Road and between Grahams Ferry and Boones Ferry roads. Construction on this last section is planned to begin in August 2026.
- Permitting has started for work north of Sherwood. Construction on the Murrayhill – Sherwood segment is planned for November 2026, and work on the St Marys – Murrayhill segment will start in September 2027.
