Transmission Vegetation Management
Eversource's Vegetation Management department maintains vegetation in and along 2,300 miles of transmission right-of-way corridors through Connecticut, Massachusetts and New Hampshire.
Each year about 25 percent of these rights-of-way are managed to control vegetation growing within the cleared and maintained areas - preventing the growth of tall trees that could interfere with the overhead facilities.
About 10 percent of these rights-of-way also have vegetation trimmed to prevent trees and branches from contacting the lines.
All work is performed in accordance with specifications conforming to utility industry best practices and compliance with federal management standards.
Massachusetts also requires detailed five year management plans that are reviewed and approved annually before Eversource can perform scheduled maintenance.
