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.

    Underlying source

Source notes

Brownfield redevelopment of former Century Aluminum smelter. Site acquired February 2026 from Century Aluminum subsidiary; acquisition price reported by multiple outlets as $200M cash plus a 6.8% minority equity interest in TeraWulf (not confirmed in the official press release text as of July 2026). Lease entity: TeraWulf's Raylan Data LLC to Anthropic PBC. The ~$19B is contracted lease revenue over the 20-year term — not capex; not recorded as an investment figure. TeraWulf indicated a $3B–$4B construction investment for two data center buildings (range, not a firm single figure; not recorded as an investment figure). Site has ~480 MW of existing power availability; 401 MW is the Anthropic lease capacity. Total site ~750 acres per news sources; TeraWulf's official PR cited 'over 250 buildable acres.' Coordinates are approximate (Hawesville town center). The Fluidstack/Abernathy JV is a separate unrelated transaction and is not part of this record.

Site connects directly to regional transmission network via on-site energized substation and multiple high-voltage transmission lines, bypassing local distribution. Big Rivers Electric filed a retail service agreement with the Kentucky PSC in April 2026 covering 482 MW transmission capacity for the Justified Data project; TeraWulf bears identified costs and risks for obtaining and transmitting capacity. TeraWulf is covering the full cost of required grid upgrades.
