The decision to remove a tree depends on several factors:
- The voltage of the power lines
- The proximity of the tree to the wires and
- The health of the tree
CenterPoint Energy works continuously to remove all trees and vegetation that will at some time interfere with the safe, reliable operation of transmission lines. Our purpose is to produce a predictable environment of low-growing vegetation in our transmission line corridors according to the utility model recognized by the Federal Energy Regulatory Commission (FERC).
We inspect and maintain our transmission rights-of-way and transmission line vegetation growth on a five-year cycle, which means that 20 percent of the circuits/lines have trees removed or trimmed annually. We make an annual aerial inspection of the rights-of-way to identify trees that are dead, dying or compromised such that they may fall onto an adjacent transmission line.
Since such trees are usually located outside the right-of-way, we try to obtain landowner permission to remove these trees before they fall. Branches that hang over into our right-of-way may be trimmed rather than removed.
