Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.

Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

Source notes

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.

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.
