Whitefield to Berlin (S136) Line Rebuild Project

Why Are We Doing This Project

Recent inspections and engineering analysis of the S136 transmission line revealed that many of the structures are in poor condition due to their age, woodpecker damage, insect damage and pole rot.

The S136 transmission line currently has 353 structures. Of these, 139 are already weathering steel and will not be replaced, eight are already weathering steel but will be replaced due to clearance issues, two will be permanently removed, and the remaining 204 wooden 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 S136 Line, a 115-kilovolt (kV) transmission line built in 1969 that is 26 miles long.

The S136 transmission line starts at the Whitefield Substation in Whitefield and ends at the Berlin Eastside Substation in Berlin. See the project map plans  – this map set is subject to change due to permitting, constructability and other considerations.

This transmission line crosses the following roads:

  • Whitefield - Route 3, Route 116, Localizer Drive
  • Jefferson - Route 115A (Meadows Road), Mill Brook Garden Road, Route 115, Red Brook Road, Jefferson Notch Road
  • Randolph - Dolly Copp Road
  • Gorham - Mineral Spring Road, U.S. Route 2, Crestwood Drive, Route 16 (Main Street), Hogan Road
  • Berlin - Cascade Alpine Brook Road

When Is The Work Being Done

  • Local and State Permitting: 3rd Quarter 2023 through 1st Quarter 2024
  • Federal Permitting: 3rd Quarter 2023 through 2nd Quarter 2024
  • Construction Start Date: 1st Quarter 2024 (Anticipated)
  • Projected In-Service Date: 2nd Quarter 2025 (Anticipated)

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.

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 recent Project Update Letter
  • Read the Project 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.

All Eversource personnel follow applicable health and safety guidelines.
