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 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.

Notice: Hunting season and the safety of our workers

With the onset of hunting seasons in Massachusetts and Rhode Island, we ask hunters to refrain from hunting on and around the Interstate Reliability Project rights-of-way and access corridors. The Project areas are active work zones for well over 100 workers through 2015. The safety of our workers is paramount, and we ask for your cooperation and consideration as you make your hunting plans.
