Transmission Vegetation Management Projects

We maintain vegetation in and along more than 2,300 miles of transmission right-of-way corridors through Connecticut, Massachusetts and New Hampshire.

Each year we maintain about 25% of the rights of way by:

  • Performing integrated vegetation management to maintain the cleared right of way
  • Trimming branches growing into the right of way towards the lines
  • Assessing and removing hazard trees from outside the maintained right of way or outside the easement
  • Performing ground and helicopter patrols to identify risks

We perform this work to prevent trees and non-compatible vegetation from growing too close to lines. All work is performed in accordance with specifications conforming to utility industry best practices and compliance with federal management standards.

Massachusetts Operational Plans

Massachusetts regulations require detailed vegetation management plans that are reviewed and approved annually before we can perform scheduled maintenance.
