Huckins Hill to Beebe River (Z180) Line Rebuild Project

Why Are We Doing This Project?

Recent inspections and engineering analysis of the Z180 transmission line revealed that many of the structures are in poor condition due to their age, woodpecker damage, insect damage, and pole rot.

The Z180 transmission line currently has 38 structures. Of these, 9 are already weathering steel and will not be replaced, while one will be removed without replacement. The remaining 28 structures will be replaced with weathering steel structures of a similar design. 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 line.

This maintenance is part of our ongoing investments to deliver reliable energy to our customers and communities.

Where Is The Work Being Done?

This work will take place within the existing right-of-way (power line corridor) of the Z180 Line, a 115-kilovolt (kV) transmission line built in 1964 that is 3.4 miles long.

The Z180 line starts at the Huckins Hill Substation in Holderness and ends at the Beebe River Substation in Campton. 

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

This transmission line crosses the following roads:

Holderness

None (access to the substation will be from the existing driveway off Route 175)

Campton

Trapper Road, Pulsifer Road, Ken Mar Drive, Stickney Road, Route 175, Champagne Circle, Silver Dawn Road

When Is The Work Being Done?

  • Local permitting: Third and fourth quarter 2022
  • State permitting: Third and fourth quarter 2022
  • Federal permitting: Third and fourth quarter 2022
  • Construction Start Date: First quarter 2023 (anticipated)     
  • Projected In-Service Date: Second quarter 2024

Restoration will be ongoing during construction for stabilization to the extent it's possible. 

This schedule is weather dependent and subject to change.

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 Start of Construction letter
  • Read the Construction Fact Sheet

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.
