Northumberland to Dummer (O154) Line Rebuild Project
Why Did We Do This Project?
Recent inspections and engineering analysis of the O154 transmission line revealed that many of the structures were in poor condition due to their age, woodpecker damage, insect damage and pole rot.
A total of 138 wooden H-frame structures have been replaced with 137 weathering steel H-frame structures. In addition, the conductor (wire) was replaced with fiber optic cable, known as Optical Ground Wire (OPGW).
These improvements are part of our ongoing investments to deliver reliable energy to our customers and communities.
Where Was The Work Done?
This work took place within the existing right-of-way (power line corridor) of the O154 Line, a 115-kilovolt (kV) transmission line built in 1946 that is 12.6 miles long.
The O154 line starts at the Lost Nation Substation in Northumberland and terminates at the Paris Substation in Dummer.
This transmission line crosses the following roads:
Northumberland
Lost Nation Road
Stark
Potter Road, Route 110 (Stark Highway), Lunn Road, Northside Road, Christine Lake Road, Paris Road
Dummer
Holt Road, Kelley Brook Road, Cedar Pond Hill, Dummer Pond Road

- State permitting: Fourth Quarter 2021
- Federal permitting: Fourth quarter 2021
- Construction start date: Third quarter 2022
- In-service date: Third quarter 2023

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
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.
