DeepGreen Western Passage underwater AI data center
Eastport, Washington County, ME
DeepGreen Western Passage underwater AI data center is an announced data center project in Eastport, ME, backed by DeepGreen Holdings LLC (Louis Wolfson). The project is sized at 15 MW. DeepGreen Holdings filed for a FERC preliminary permit (Feb. 2026) for a tidal-powered, submerged AI data center in the Western Passage, scaled down from 51 MW/170 turbines to 15 MW with 16-34 marine hydrokinetic turbines on a 27-acre footprint. FERC accepted the permit application for review in Aug. 2026, but Eastport's council adopted a 180-day moratorium (Aug. 13, 2026), citizen ban ordinances are pending, and the Passamaquoddy Tribe, Center for Biological Diversity and the city have moved to intervene. (Source dated 2026-08-13.) [Reviewed 2026-10-09: verified] FERC accepted the preliminary permit application in August 2026; the project is in the early permitting stage with active local opposition and a 180-day moratorium in place.
