Welcome to the Interstate Reliability Project

The Interstate Reliability Project is a 345-kilovolt (kV) transmission project in an existing transmission right-of-way. It is one of four New England East-West Solution (NEEWS) 345-kV transmission projects serving portions of New England. The Interstate Reliability Project is needed to meet the demand for electricity and support the reliable delivery of electricity to customers under many different conditions.

Project Information

The Project begins in Millbury, Massachusetts and continues along the existing transmission line rights-of-way (ROW) into North Smithfield, Rhode Island. It continues west to Burrillville, Rhode Island and into Connecticut where it will connect to a new line being constructed by Connecticut public utility, Northeast Utilities.

Project Update Notice - Rhode Island for the weeks and November 30th and December 7th

The wire pulling has been completed for the last section of the 366 Line from Central Street in Millville to the West Farnum Substation off Greenville Road in North Smithfield. Over the next few weeks, spacers will be installed at 200-foot intervals between the parallel wires to prevent damage from short circuits, wind and ice, and to ensure reliable delivery of electricity.

Over the next few weeks, the remaining construction work will be completed for the 328 Line from the Sherman Farm Road Switching Station in Burrillville to the West Farnum Substation in North Smithfield.

Project Update Notice - Massachusetts

With the completion of construction work for the Massachusetts segment of the Interstate Reliability Project, National Grid's onsite crews are performing restoration work at select sites along the right-of-way.

We will be posting periodic project notifications about restoration activity along the right-of-way into Spring 2016.

Project Map

The Interstate Reliability Project encompasses approximately 15.4 miles of ROW in Massachusetts through the towns of Millbury (.7 mile), Sutton (6.2 miles), Northbridge (.3 mile), Uxbridge (7.6 miles), and Millville (.6 mile); and 22.5 miles in Rhode Island through the towns of North Smithfield (9.3 miles) and Burrillville (13.2 miles).

Notice: Utility rights-of-way are off limits to off-road drivers

National Grid reminds off-road drivers that utility rights-of-way are private property where unauthorized dumping and trespass by motorized vehicles is unlawful. These rights-of-way are a critical part of the company's electric and gas network. Limiting activities within the corridors protects the public, avoids damage to company facilities and supports the reliability of electric and gas service. For more information, click here.
