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.

Project Facts: 

  • Route length: Approximately 12.1 miles
  • Town/city: Acushnet, Dartmouth, New Bedford, and Fall River, MA.
  • Line voltage: 115,000-volt (115-kV) overhead transmission line
  • Siting review by: Energy Facilities Siting Board (EFSB)
  • Public Open Houses: Initially held on September 26 and 27, 2018; Additional virtual open houses planned for June 2021 

Estimated Timetable (subject to change, pending necessary approvals): 

  • File Siting Petition with the EFSB: 2021
  • EFSB Public Hearing: 2021
  • Petition Decision from the EFSB: 2023
  • Start of construction: 2023
  • Estimated in-service date: 2024


To construct and operate the new 115-kV overhead transmission line, Eversource and National Grid will file a petition with the Massachusetts EFSB for approval. The petition filing is part of the regulatory review process, as defined by Massachusetts state statutes.


Eversource and National Grid will engage town officials, residents, businesses, community groups and other stakeholders via municipal briefings, open houses, mailings and meetings to answer questions and listen to concerns. As the proposed project proceeds through the siting and permitting process, we will continue keep you informed.
