Farmwood Substation to Webster Substation (F139 / V182) Simultaneous Line Rebuild Project

Why Are We Doing This Project?

Recent inspections and engineering analysis of the F139 and V182 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 289 wooden H-frame and monopole structures are being replaced with weathering steel H-frame and monopole structures one for one. In addition to structure replacements, the F139 line will receive new conductor (wire), and fiber optic cable, known as Optical Ground Wire (OPGW). The V182 line already has these upgraded components. Completing the work on these co-located lines simultaneously allows Eversource to minimize the impact on our neighbors, the environment, and capitalize on economy of scale.

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 Eversource‚Äôs existing right-of-way (power line corridor). The F139 Line and V182 Line are 115-kilovolt (kV) transmission lines that are 14.6 miles long. 

These lines start at the Farmwood Substation in Concord, NH and terminate at the Webster Substation in Franklin, NH.

This transmission line crosses the following roads:


Sanborn Road, Hoit Road, and Route 132


Boyce Road, Old Schoolhouse Road, West Road, Interstate 93, and Intervale Road.


Fiddlers Choice Road


South Main Street, Smith Hill Road, Punch Brook Road, Route 127, Flaghole Road, Chance Pond Road, and Garneau Road

  • Local permitting: First and second quarter 2023
  • State permitting: First through third quarter 2023
  • Federal permitting: First through third quarter 2023
  • Construction start date: August 2023
  • Projected in-service date: Fourth quarter 2024 (anticipated)

Construction Updates

See our construction fact sheet for more information about activities occurring in your neighborhood.

Community Outreach

 Eversource is 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.

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 Project Introduction 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.
