Eversource is proposing to construct 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 proposed new line would be constructed between our Carver Substation and our Kingston Substation.

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

To construct and operate the proposed transmission line, Eversource must file a petition with the Massachusetts Department of Public Utilities (DPU) for approval. The petition filing is part of the regulatory review process, as defined by Massachusetts state statutes.

As a part of the evidentiary process, the DPU hosted a public comment hearing on October 27, 2020. To see the presentation from the hearing, click here.

We will be engaging with town officials, residents, businesses, community groups and other stakeholders through municipal briefings, open houses and meetings – answering questions and listening to concerns about the project.

Eversource hosted public open houses in Carver on August 13, 2019, and in Kingston on August 14, 2019, to give local residents, business owners, and other interested stakeholders an opportunity to learn more about the project, ask questions, and provide feedback.

We will continue these outreach efforts as the proposed project proceeds through the siting process and into construction.
