Thurston County tree pruning projects
Fallen trees and limbs are the main cause of power outages in Western Washington, and can cause safety concerns if tree branches come in contact with energized power lines. By pruning trees that are growing near power lines, we can decrease the likelihood of tree-related power outages and ensure our customers stay safe.
To provide safe and reliable electric service to our customers in Thurston County, tree crews are working in 2012 to trim and remove trees along nearly 200 miles of distribution lines and 10 miles of transmission lines in the area. This work is part of our regular maintenance program, which entails pruning trees on a regular 3-6 year cycle depending on various factors, including growth rate, limb configuration, proximity to power lines, and power line voltage. PSE utilizes certified arborists to determine how often trees should be pruned, and uses best management practices to complete the pruning with minimal stress to trees.

In honor of Arbor Day this spring, PSE and a team of volunteers planted several flowering crabapple, rhododendron and red cedar trees in the Tenino, Rainier and Rochester areas. In addition to regular maintenance of the vegetation near PSE’s energy equipment, planting the right tree in the right place to prevent tree- and limb-related outages is also part of our commitment to electric service reliability.
What is a distribution line?
Distribution lines are critical links in the electrical system moving power from electrical substations through distribution transformers directly to homes or businesses. Unlike transmission lines, distribution lines typically carry less than 55 kV; PSE's distribution lines are typically 12.5 kV. Distribution lines can be installed both above and below ground.
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 and will notify residents and businesses near the project area when tree pruning will occur. We strive to complete the work with as little disruption as possible.
