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.
