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 has been completed from the Route 146 crossing to Mendon Road, and the Lackey Dam Road area to Williams Street and West Hartford Avenue. Tree crews will continue along the right-of-way over the next few weeks as follows:
Work is underway at the Millbury #3 Switching Station, located off Cross Street in Millbury. National Grid's contractor is performing various equipment upgrades and additions within the existing fence line of the Station, which will continue over the coming months.
Tree clearing crews have completed clearing the right-of-way from the Sherman Farm Road Switching Station to the West Farnum Substation. Crews have mobilized back to the Sherman Farm Road area (Ocean State Power) and are now moving west towards the Connecticut border.
Foundation drilling activity is underway at various locations along the right-of-way. Foundation drilling crews will continue working along the corridor from Sherman Farm Road to the West Farnum Substation.

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.
