Whidbey Island vegetation management
Spring 2015 project updates
- In 2015 we expect to clear line segments 1A, 2A and 3A south of Deception Pass.
- In 2014 we completed clearing segments -1A, -1, -2, -3, as well as segment 22 near Whidbey Naval Air Station in Oak Harbor.
- Please refer to the project map for segment locations.
- Customers will receive advance notice of any proposed clearing, and will have an opportunity to speak with PSE real estate and vegetation management representatives prior to any work being done.
Historically, fallen trees and tree limbs are the main cause of power outages on Whidbey Island. This was particularly evident during the winter of 2006 when fierce rains and winds caused trees and branches to fall into transmission lines and knock out power to the entire island. Accordingly, PSE is accelerating its efforts on Whidbey Island and improving our system's reliability by proactively working to reduce tree-related outages in our transmission corridor. Based on a comprehensive review of outage history and an independent review of our storm response and procedures, PSE has identified specific existing transmission line corridors where the removal of trees with a mature height of 25 feet or more can improve service reliability.
This initiative is a unique, multi-year effort to improve electric reliability on Whidbey Island through enhanced vegetation management; it will take several years to clear around the transmission line corridor. Priority for vegetation removal is being given to line segments with the greatest risk of tree-related outages.
What is vegetation management?
Vegetation management involves a variety of programs and techniques designed to protect power lines from the impacts of nearby trees. These programs may include pruning, tree removal, herbicides and smart planting practices. All actions are taken to keep the public safe and the lights on.
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.
