Acushnet to Fall River Reliability Project

To improve system reliability, Eversource and National Grid are proposing a joint project to construct a 115-kilovolt (kV) transmission line on existing Eversource and National Grid rights of way from Acushnet to Fall River.

The proposed project would improve system reliability in Southeastern Massachusetts and Rhode Island and would also include upgrades at Eversource’s High Hill Substation in Dartmouth and Wing Lane Substation in Acushnet.

Eversource’s portion of the proposed transmission line will extend approximately 7.9 miles, passing through Acushnet, Dartmouth, and New Bedford. The line would then continue for approximately 4.2 miles in Fall River.

The petition filing is part of the regulatory review process, as defined by Massachusetts state statutes.


Eversource and National Grid will be engaging town officials, local residents, business owners, community groups and other interested stakeholders through briefings, open houses, mailings and meetings as an opportunity to learn more about the project, ask questions and provide feedback. As the proposed project proceeds through the siting and permitting process, we will continue keep you informed.
