Power and water

Proposed to be powered by roughly 330-350 marine hydrokinetic (tidal) turbines in Cook Inlet; the developer describes tying in with the Alaska Energy Authority's planned Cook Inlet PowerLink transmission line, but AEA says the company has not contacted it.

Underwater server 'hives' cooled by ambient seawater; the developer claims no freshwater use.

Notes on the record

The plan calls for 66 modular data-center pods in a 1,650-acre seabed envelope west of Nikiski (East Foreland corridor), 45-166 ft deep, with a 3.5-mile cable to a Nikiski landing. Only preliminary studies are proposed (about $4.5M over 4 years). The pin is the Nikiski hamlet; the site is offshore to the west.

Which document closes each gap

Cooling method and water use: The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
Tax abatements or other public subsidy: The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised: The economic development application or incentive agreement, which usually states a job commitment and a clawback.
Which utility serves it: The electric service agreement or the utility's filing with the state public utility commission.
