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 system as more renewable energy flows north from California. When complete, the project will deliver more reliable and cost-effective electricity to PGE customers.
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-kV transmission line for increased efficiency
- Upgrades PGE’s Sherwood, Murrayhill and St Marys substations in southwest Washington County for enhanced reliability
All construction will take place within existing easements or on PGE property. Some activities may temporarily impact surrounding communities, including possible traffic disruptions. PGE and our contractors will notify affected residents and businesses ahead of time to minimize inconvenience.

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 on the McLoughlin-Pearl-Sherwood segment is now underway. Visit this webpage for updates as they become available.
