TeraWulf has amended its electric service agreement with Kentucky Power, an AEP company, to secure an additional 500 MW of power for its Muskie Data Campus in eastern Kentucky. The move doubles the site's contracted capacity from 500 MW to a full 1 GW.
The first 500 MW phase is still targeted to begin ramping in 2028. With the new agreement, delivery of the second 500 MW phase has been advanced from 2030 to 2029, subject to approval from the Kentucky Public Service Commission. Kentucky Power is also developing a 765-kV/345-kV substation to serve the campus.
TeraWulf acquired the Muskie site in May 2026 and says it is now evaluating the campus's potential to scale up to 2 GW over time.
"Customer interest in Muskie has been tremendous, and power availability is central to those conversations," said Paul Prager, TeraWulf's Chairman and CEO. "Securing the next 500 MW and moving its planned delivery into 2029 gives us greater flexibility to meet prospective customers' deployment needs."
TeraWulf develops, owns and operates large-scale power-backed digital infrastructure for high-performance computing and AI workloads, with its Lake Mariner Data Campus in New York alongside development projects in Kentucky, New York and Maryland. Full details are in the company's press release.
