Massachusetts and eight other Northeast states have issued a Request for Information (RFI) seeking proposals for interregional transmission projects. The goal is to improve grid reliability, lower electricity costs, and support economic development, according to the Massachusetts government website.
The effort is led by the Northeast States Collaborative on Interregional Transmission, formed in 2023. Participating states include Connecticut, Delaware, Maine, Maryland, New Jersey, New York, Rhode Island, and Vermont. Projects must span at least two of the regions served by ISO New England, New York ISO, or PJM Interconnection.
Massachusetts Energy and Environmental Affairs Secretary Rebecca Tepper stated the collaboration could help deliver more affordable electricity. Ashley Gagnon, the state’s Federal and Regional Energy Affairs Senior Director, noted this is a first step toward evaluating cross-border transmission projects.
Entities such as energy developers, consumer advocates, and industry experts are invited to submit proposals by October 23, 2025. The Collaborative’s strategic plan, issued in April 2025, provides guidance for regional and federal policy development and supports standardizing transmission equipment.
Officials from other states, including Katie Dykes of Connecticut, Celina Cunningham of Maine, and Paul G. Pinsky of Maryland, have also expressed support for the joint effort. The states aim to find new ways to manage energy costs and improve grid performance across the region.
