TeraWulf Says an Amended Electric Service Agreement Increases the Contracted Power at Its Muskie Data Campus

TeraWulf calls itself "a vertically integrated owner, developer and operator of large-scale digital infrastructure." On October 5, 2026 it announced, in a release on its own website, that it had executed an amended and restated electric service agreement with a utility for its Muskie Data Campus in eastern Kentucky. The amendment increases the contracted power capacity at the campus from 500 MW to 1 GW. Parts of the release follow, not the whole.

The company acquired the campus in May 2026 "for phased development as an AI and high-performance computing campus." The utility is developing a substation, connected to the regional transmission network, to serve the site.

The Phases, and a Potential

The amendment "advances planned delivery of Muskie's second 500 MW phase from 2030 to 2029, subject to Kentucky Public Service Commission approval" and the utility's construction schedule. Development, the release says, "will proceed consistent with the requirements of" the governor's Executive Order on Data Center Development (2026-494). The first 500 MW phase "remains targeted to begin ramping in 2028."

Planned delivery in 2029 rests on two things outside the company: the commission's approval and the utility's construction schedule.

The company's chairman and chief executive is quoted as saying that customer interest in the campus "has been tremendous, and power availability is central to those conversations." Securing the second phase and moving its planned delivery into 2029, the release quotes the chief executive as saying, gives the company "greater flexibility to meet prospective customers' deployment needs." The company also "continues to evaluate the campus's potential to support up to 2 GW over time, subject to additional utility planning, infrastructure and agreements."

An Approach, an Approval and a Limit

The amendment, the release says, "follows TeraWulf's approach to large-scale development in Kentucky: coordinate with the utility on the infrastructure needed to serve the campus, provide financial protections for utility investment and structure the agreement to benefit existing customers." In August, it adds, the state commission approved the separate electric service agreement for the company's Justified Data Campus in Hawesville, "finding that its terms adequately protected existing customers and appropriately allocated the costs and risks of serving that project."

The release's forward-looking statements say that "There can be no assurance that future developments will be those that have been anticipated."
