Provider notes
Energy. 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.
Water. TeraWulf stated at community meetings that no river water or municipal water will be used. Advanced closed-loop liquid cooling system; company stated campus will use less water over several years than the former aluminum smelter consumed in a single day. No reported MGD figure available.
Community. Online petition with 1,200+ signatures asking county officials, the governor, and the state utility regulator to pause approvals pending disclosure of energy, environmental, and infrastructure impacts. Hancock County Judge-Executive Johnny Roberts publicly supportive, citing 100–120 high-paying permanent jobs and significant new annual tax revenue for schools and emergency services. Opposition concerns center on water use, traffic, and environmental effects. TeraWulf held community meetings (March 2026) to address water and cooling questions.
These reviews flag conflicting scope, inconsistent source text or support that has not been established. A withheld value may appear in the explanation, but is not displayed as an established field. The upstream row remains attributed under Sources.
- Announced investment: The source note says the $3–4 billion construction figure is a range, not a firm single figure, and excludes it from investment.
What the source record says
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 official PR text fetched). Lease entity: TeraWulf's Raylan Data LLC to Anthropic PBC. The ~$19B is contracted lease revenue over the 20-year term — not capex; excluded from investmentUsd. TeraWulf indicated a $3B–$4B construction investment for two data center buildings (range, not a firm single figure; excluded from investmentUsd). 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). Fluidstack/Abernathy JV is a separate unrelated transaction — excluded from this record.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
