DeepGreen Western Passage SPV LLC has proposed a 51-megawatt tidal energy project near Eastport, Maine, which includes an underwater AI data center. The company submitted a preliminary permit application to the Federal Energy Regulatory Commission on Feb. 11, seeking a 48-month permit for environmental studies.

The project aims to create a managed energy hub with 170 tidal turbines and 34 AI-server racks, estimated to cost $415 million. Funding will come from private equity and federal tax credits. DeepGreen is pursuing agreements with Eastport and the Passamaquoddy Tribe. A similar preliminary permit has been filed for a site in Cook Inlet, Alaska.
