Hancock County Data Center
Project of TeraWulf
Where it stands
TeraWulf's Justified Data Campus repurposes the idled Century Aluminum Hawesville smelter in Hancock County. The campus is described as 480 MW. On August 21, 2026, the Kentucky PSC approved a retail electric service agreement for up to 482 MW, and TeraWulf estimates $4.0-4.5B for site development and initial data halls. A roughly 401 MW, 20-year lease with Anthropic is reported. No passage confirms construction milestones or energized capacity. One stock-news item (P8) says TeraWulf 'already operates' the campus, but contemporaneous reporting calls it 'planned' and says the company 'intends to repurpose' the smelter, so it is treated as pre-construction.
