New Hampton to Holderness (E115) Line Rebuild Project

Why Are We Doing This Project?

Recent inspections and engineering analysis of the E115 and E115 Tap transmission lines revealed that many of the structures are in poor condition due to their age, woodpecker damage, insect damage and pole rot.

A total of 173 wooden H-frame structures are being replaced with weathering steel H-frame structures. Two additional wooden H-frame structures are being removed without a replacement. In addition, the conductor (wire) is being replaced, and fiber optic cable, known as Optical Ground Wire (OPGW), is being installed the entire length of the corridor.

Improvements are part of our ongoing investments to deliver reliable energy to our customers and communities.

Where Is The Work Being Done?

This work is taking place within two of Eversource’s existing rights-of-way (power line corridor). The E115 Line is a 115-kilovolt (kV) transmission line built in 1964 that is 15.4 miles long. This line starts at the Pemigewasset Substation in New Hampton and terminates at the Huckins Hill Substation in Holderness. 

The E115 Tap is a 115kV transmission line built in 1964 that is 0.5 miles long. This line starts at Ashland Substation in Ashland and connects to the E115 transmission line on the western side of I-93 in Ashland.

See the project plans. (This map set is currently in draft form and is subject to change due to permitting, constructability and other considerations.)

These transmission lines cross the following roads in New Hampton, Bristol, Bridgewater, Ashland and Holderness:

    Community Outreach

    We're committed to engaging municipal officials, residents, businesses, community groups and other stakeholders about upcoming project activities through municipal briefings, mailings, site meetings, virtual meetings and door-to-door outreach, while adhering to COVID-19 social distancing and other related health and safety guidelines.

    We utilize a variety of outreach methods to ensure that all customers and property owners along our transmission lines receive adequate and timely information about our projects. For this Project, we will be sending periodic updates as letters mailed directly to all stakeholders, as well as a combination of the following additional methods:

    • Door-to-door outreach
    • Site visits (upon request)
    • Virtual meetings (upon request)
    • Signage placed strategically near construction areas or in residential areas
    • Regular field presence to ensure the safety of our customers, nearby property owners, and our construction crews
    • Read the most recent project Start of Construction letter

    Commitment to Safety

    We take every safety precaution while working in local communities, and all people working on the construction project carry identification. The project work will not interrupt electric service to homes or businesses.

    We remain committed to prioritizing public health as well as the health of employees and contractors during COVID-19. All Eversource personnel follow applicable health and safety guidelines to help prevent the spread of COVID-19.
