Mystic to Woburn Project
Why Are We Doing This Project?
This project improves reliability and addresses the growing need for electricity in the area. We completed construction of the project in March 2024, and the new transmission line was energized and put into service on March 30, 2024.
Where Is This Work Being Done?
This project included a new 115-kilovolt (kV) underground transmission line that connects Eversource’s Mystic Substation in Everett and Eversource’s Woburn Substation.
The line extends approximately 8 miles between two existing substations, passing through Everett, Boston (Charlestown), Somerville, Medford, Winchester, and Woburn. The project also included improvements within the existing fence lines of the Woburn and Mystic substations.
Information about the project is also available in Spanish, Portuguese and Haitian Creole.

Construction Updates
Community Outreach
Before starting construction in a community, we will mail start of construction letters to property owners along the route and conduct door-to-door outreach to nearby property owners, residents and local businesses.
Door-to-door outreach efforts for the project are currently limited to mailing letters and leaving door hangers without knocking (to avoid face-to-face communication). Full in-person communication efforts will resume when appropriate.
Have Questions?
Keeping the lines of communication open is an important part of our work in your community.
