[Project No. 15423-000]
DeepGreen Cook Inlet SPV, LLC; Notice of Preliminary Permit
Application Accepted for Filing and Soliciting Comments, Motions To
Intervene, and Competing Applications
On February 11, 2026, as supplemented on June 26, 2026, DeepGreen
Cook Inlet 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 Cook Inlet Subsea-Compute &
Infrastructure Hub Project (DeepGreen Project or project) to be located
in the Upper Cook Inlet, East Foreland Corridor, Kenai Peninsula
Borough, Alaska. 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: (1)
approximately 330-350 marine hydrokinetic turbines utilizing a
proprietary universal docking cradle system; (2) 66 modular subsea-
compute hives (data center pods) integrated within the turbine array to
utilize direct-coupled power and passive subsea cooling; (3) an
approximately 3.5-mile long, 115 kV hybrid power/fiber-optic armored
subsea cable; (4) a subsea cable landing site within the Nikiski
Industrial Corridor, positioned between the Agrium Kenai Nitrogen
Operations and the Kenai Liquefied Natural Gas Plant; and (5)
appurtenant facilities. The estimated annual generation of the
DeepGreen Project would be 100 megawatts, which would primarily be
utilized to power the subsea data center. Spare electricity could be
diverted to the grid via an interconnect with the Alaska Railbelt Grid
at a dedicated terrestrial substation.
