115kV Line (Mystic to Woburn)


Eversource Mystic to Woburn Line Project


The Mystic to Woburn Line Project will install a new 115-kilovolt (kV) underground transmission line connecting the Mystic substation in Everett, MA to the Woburn substation in Woburn, MA.  The line will extend approximately 8 miles, traversing Boston (Charlestown), Everett, Medford, Somerville and Winchester and Woburn.
