Hull Street Energy acquires FirstLight USA's U.S. generation fleet, including hydroelectric and solar assets
Type: Acquisition · Technology: Hydro · Country: United States · Announced: 2026-05-20
Hull Street Energy signed an agreement to acquire FirstLight USA from the Public Sector Pension Investment Board, acquiring a portfolio of nearly 1,400 megawatts of clean generation in the Northeast. The transaction includes Northfield Mountain, a 1,168-megawatt pumped storage hydro facility in Massachusetts—the largest energy-storage facility in New England—as well as 14 hydroelectric stations across Connecticut, Massachusetts, and Pennsylvania. Additionally, the deal encompasses three operational solar and battery facilities in the Northeast. Hull Street Energy, which has decades of experience in hydroelectric asset acquisition and operation, will become one of the nation’s leading hydropower investors following the closures of this acquisition and a prior 2025 agreement with Consumers Energy to acquire 13 hydroelectric dams in Michigan. The combined portfolio will total approximately 1,200 megawatts of flexible pumped storage hydro capacity and nearly 400 megawatts of high-quality hydroelectric capacity.
