Why Are We Doing This Project?

Recent inspections and engineering analysis of the U199 transmission line revealed that many of the structures are in poor condition due to their age, woodpecker damage, insect damage and pole rot.

The U199 transmission line currently has 116 structures. Of these, eight are already weathering steel and will not be replaced. This project will replace the remaining 108 structures 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. 

Improvements are 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 U199 Line, a 115-kilovolt (kV) transmission line built in 1971 that is 9.75 miles long. 

The U199 transmission line starts at the Littleton Substation in Littleton and ends at the Streeter Pond Tap Station in Sugar Hill.

See the project plans (PDF), this map set is subject to change due to permitting, constructability and other considerations.

This transmission line crosses the following roads:

Littleton

Foster Hill Road, Old Partridge Lake Road, Route 18, Route 135, State Ledge Road, US Route 302, Eustis Hill Road

Bethlehem

None

Sugar Hill

Streeter Pond Road

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 (PDF)
• Read the project fact sheet (PDF)

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.
