Which trees will PGE prune?
As we rotate through our service territory, our foresters examine trees for trouble spots. We look for branches that are close to power lines as well as branches that could fall during a storm and hit a line. We also search for diseased or dying trees.
Our crews will work on any trees determined to be a possible threat to power lines. Usually, these are trees that are planted directly below the lines in a parking strip and have grown too tall. But we sometimes will prune the branches from a tree outside this right-of-way tree if it is getting too close to the power line. The general rule is 10 feet of clearance.
How we prune
Our top priorities are to ensure safe, reliable power while also guarding the health of the tree. That’s why we won’t just arbitrarily cut a tree.
If, for example, the branches of a large elm or oak completely surround the power lines, we often prune out a u-section in the middle of the tree to provide plenty of clearance for the lines. This is much healthier for a tree than reducing its entire tree canopy.
How our crews are trained
Our tree crews are highly trained and must meet a stringent qualification process. They undergo a two-year apprenticeship during which they study tree biology and tree pathology, as well as how to work safely around power lines. Each year they safely prune thousands of trees.
