Whitefield to Northumberland (D142) Line Rebuild Project

Project Overview

We are replacing existing wooden pole structures in Whitefield, Lancaster and Northumberland, New Hampshire, as part of our ongoing investments to deliver reliable energy to our customers and communities.

This work is taking place within the existing right-of-way (power line corridor) of the D142 line, a 115kV line built in 1948. The line is 18 miles long and starts at the Whitefield Substation in Whitefield and terminates at the Lost Nation Substation in Northumberland.

202 structures are being removed or replaced and fiber optic cable, known as Optical Ground Wire (OPGW), is being installed the length of the line.
