On May 13, 2026, FERC granted rehearing, in part, of its November 26, 2025 order issuing a new license to Bear Swamp Power Company, LLC (Bear Swamp) for its 676 megawatt (MW) Bear Swamp Hydroelectric Project (Project) on the Deerfield River in Berkshire and Franklin Counties, Massachusetts. FERC’s order addressed Bear Swamp’s rehearing request challenging license Article 403(2), which required maintenance of impoundment elevations between 830 and 835 feet from 10 a.m. to 12 p.m. on certain days per year to support whitewater boating. In its rehearing order, FERC revised license Article 403(2) to clarify that Bear Swamp would not be in violation of its license for deviating from the impoundment elevation requirements when doing so at ISO-NE’s direction to maintain grid reliability.
