N12/M13 Transmission Upgrade Project

Project Overview

N12/M13 Transmission Upgrade Project

Fall River & Somerset, MA

N12/M13 Transmission Upgrade Project

The N12/M13 Transmission Line Upgrade Project is one of several planned infrastructure upgrades in southeast Massachusetts needed to support the growing transmission needs of the area well into the future. The transmission grid serves as the backbone of our electric system and is vital to our region's safety, security, and economic prosperity.

The N12/M13 Transmission Line Upgrade Project is a proposed reliability project to separate two transmission lines currently carried on one set of transmission structures.

Separating the lines will reduce the chances of an outage affecting both lines. The wires will also be upgraded to support additional electric current.

The 1.8-mile segment of overhead power lines to be reconstructed begins on the west shore of the Taunton River in Somerset (Riverside Avenue at Pottersville Substation), crosses the river to Fall River, and continues east in an existing transmission corridor to the Sykes Road Substation.

The design and permitting of the proposed project is ongoing, with construction anticipated to start in late 2023 or early 2024.

Public Hearing

National Grid recently filed an application with the Department of Public Utilities (DPU) to seek approval for this upcoming Project. Through the application process members of the public and all interested parties will have the opportunity to ask questions and make comments on the proposed project through an DPU-sponsored public comment hearing.

The DPU conducted a remote public comment hearing regarding the Project on Thursday, March 30, 2023.
