Welcome to National Grid's Interstate Reliability Project web site. Here you will learn more about National Grid's proposed Interstate Reliability Project in Massachusetts and Rhode Island.

The Interstate Reliability Project is a proposed 345-kilovolt (kV) transmission line that strengthens the interstate transfer of electricity capability among Connecticut, Rhode Island and Massachusetts and improves electric reliability in all three states. The proposed line will begin in Millbury, Massachusetts and travel in the vicinity of Route 146 into North Smithfield, Rhode Island. It will then travel west to Burrillville, Rhode Island and into Connecticut where it will connect to a Northeast Utilities line. We propose to locate the new transmission line in existing utility rights-of-way.

The Interstate Reliability Project is a one of four New England East-West Solution (NEEWS) 345 kilovolt (kV) transmission projects. These related projects will strengthen the southern New England transmission grid and improve electric reliability for all customers - even on the hottest and coldest days of the year - when one or more power plants or segments of transmission line are unexpectedly not operating.
