Concord to Bow (P145) Line Rebuild Project

Why Are We Doing This Project?

Recent inspections and engineering analysis of the P145 transmission line revealed that many of the structures are in poor condition due to their age, woodpecker damage, insect damage and pole rot.

The P145 transmission line currently has 165 total structures. Six of those are weathering steel, and the remaining 159 wooden H-frame and monopole structures are being replaced with 154 weathering steel structures of a similar design. Five wooden 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 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 P145 Line, a 115-kilovolt (kV) transmission line built in 1966 that is 12.5 miles long.

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:

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.
