How Often We Maintain Vegetation
We schedule vegetation management along our electric distribution system in 4 to 5 year cycles, with occasional mid-cycle trimming for locations that cannot wait until the normal cycle.
We also track performance of different parts of our system, making note of and prioritizing tree trimming and removal in areas that routinely experience outages due to trees.
When crews perform tree trimming around power lines, clearance is determined based on common growth rates of the trees of New England. Our practices meet the standards of the International Society of Arboriculture (ISA) and the American National Standard
