Whitefield to Northumberland (D142) Line Rebuild Project

This project is complete

Why Did We Do This Project?

Recent inspections and engineering analysis of the D142 line revealed that many of the structures are in poor condition due to their age, woodpecker damage, insect damage and pole rot.

A total of 202 wooden H-frame structures are being removed or replaced with weathering steel H-frame structures. 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 Was The Work Done?

This work is taking place within the existing right-of-way (power line corridor) of the D142 line, a 115-kilovolt (kV) transmission line built in 1948 that is 18 miles long.


The D142 line starts at the Whitefield substation and terminates at the Lost Nation substation in Northumberland.

This transmission line crosses the following roads:


Lancaster Road (Route 3), Jefferson Road (Route 116), Hatfield Drive, Nutting Road


Wesson Road, Portland Street (Route 2), North Road, Grange Road


Page Hill Road, Lost Nation 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, 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 are 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
