To improve reliability and address the growing need for electricity, Eversource is preparing to construct its portion of the Woburn to Wakefield Line Project.

At Eversource, we're always working to serve you better. This project includes a new 345-kilovolt (kV) underground transmission line that will connect Eversource’s Woburn Substation in Woburn and National Grid’s Wakefield Junction Substation in Wakefield, Mass.

The line will extend approximately 8.5 miles between two existing substations, passing through Woburn, Winchester, Stoneham, and Wakefield. The project also includes improvements within the existing fence lines of the Woburn and Wakefield substations.

Eversource will be constructing the new line from the Woburn Substation through Woburn, Winchester and Stoneham to the Wakefield border. For more information specific to the Town of Wakefield, please visit National Grid's website.

Energy Facilities Siting Board

For an electric transmission line project, such as the Woburn to Wakefield Line Project, the Massachusetts Energy Facilities Siting Board (EFSB) Petition Filing is part of the regulatory review process, as defined by Massachusetts state statutes.

On February 27, 2017, Eversource received approval from the EFSB to construct the Woburn to Wakefield Line Project.

Traffic Management Plans

Working in consultation with town officials, Eversource is developing Traffic Management Plans (TMPs) for the construction of the Woburn to Wakefield Line Project.

The TMPs include, among other things, conditions specific to routing by the EFSB in its decision, a site plan showing underground line location, hours of construction, and area-specific traffic controls.

Please note, TMPs are subject to change and may be updated.

Construction Updates

Eversource remains committed to keeping neighbors, businesses and all community members up to date on project activities, including during construction.

Construction will begin in the second quarter of 2019, after all necessary permits have been received. Please note that the project work is not expected to interrupt electric service to homes or businesses.


Beginning in June 2018, crews will be taking soil samples at locations along the project route to evaluate the condition of the soil. Each boring location will have appropriate traffic controls, such as signs and police officers, as needed. The work at each location will last approximately 4-8 hours, depending on the weather and field conditions.

Please note that this activity does not indicate the start of construction in Winchester. Residents will be notified when the overall construction of the project is about to start (estimated to be in the second quarter of 2019), and again when construction is anticipated in your neighborhood.
