DeepGreen Western Passage SPV LLC; Notice of Preliminary Permit Application Accepted for Filing and Soliciting Comments, Motions To Intervene, and Competing Applications

On February 11, 2026, and supplemented and amended on June 8, 2026 and July 30, 2026, DeepGreen Western Passage SPV LLC, filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act (FPA), proposing to study the feasibility of the DeepGreen Western Passage Subsea-Compute & Infrastructure Hub Project No. 15424-000 (project), to be located in the Western Passage of the Bay of Fundy in the North Atlantic Ocean near the Town of Eastport, Washington County, Maine. The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term. A preliminary permit does not authorize the permit holder to perform any land-disturbing activities or otherwise enter upon lands or waters owned by others without the owners' express permission.

The proposed project would consist of the following new features: (1) a 3.5-meter-high and 24-meter-wide subsea modular universal docking cradle; (2) thirty-four 12-meter-long and 4.2-meter-diameter subsea compute pods; (3) a 1.8-meter-diameter spherical and elevated tidal sensing power platform; (4) up to 16 marine hydrokinetic turbine-generator units, each rated at 300-kilowatt (kW); and (5) a 1.5-mile-long hybrid power-and-fiber subsea cable operating at 13.8 kilovolts (kV). The proposed project would be configured as a behind-the-meter captive generation loop without a grid connection.
