Eversource is constructing a new 115-kilovolt (kV) transmission line between Carver and Kingston, Mass. This upgrade is one of a group of projects designed to improve the reliability of the electric system serving southeastern Massachusetts, both today and in the future.

The new line is being constructed between our Carver Substation and our Kingston Substation.

The project route runs approximately 8 miles within a right of way (power line corridor), passing through portions of Carver, Plympton and Kingston.
