The Interstate Reliability Project is a proposed 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.
The proposed 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.

Tree clearing from the Millbury #3 Substation to the Rhode Island border is 81% completed. The remaining sites are where environmental restrictions and access limit the work. These areas will be noted in future newsletters. The tree crews have moved across the Rhode Island border in Millville and are now working in North Smithfield.
The drilling stage of construction continues in a southerly direction following the tree clearing path with the foundation crews close behind. Structures have been erected starting at the Millbury #3 Switching Station moving across Providence Street, along the corridor behind Heritage Road, and continuing to Boston Road.
Tree clearing started at Central Street and moved towards Pratt Pond and Connector Road. Last week, a portion of the Mountain Road tree clearing was completed. Work will continue in the right-of way area from East Harkness Road, crossing Great Road, Victory Highway, and School Street and moving to the Branch River Industrial Park area.
Cable installation for segments of the 341 Line will begin during the last two weeks in October near the Ocean State Power site off Sherman Farm Road in Burrillville, as well as in the corridor that crosses the haul road at Holliston Sand, Pound Hill Road, Old Oxford Road and Bearskin Farm Road in North Smithfield.

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).
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.
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.
