TeraWulf data centers: 6 sites mapped

TeraWulf began as a bitcoin miner and is now selling power and buildings to artificial intelligence companies. Its first campus, Lake Mariner, sits on 180 acres outside Buffalo, New York, at a former coal-fired power plant, where the company mined cryptocurrency before turning the site toward AI and high-performance computing; Core42 and Fluidstack are live customers there, the site is headed for 750MW with the potential to reach 1GW, and Fluidstack's capacity goes to Anthropic under an arrangement Google backstops.

Google has taken a 14 percent stake in the Nasdaq-listed company across that deal and a second one covering a Texas site at Lubbock. TeraWulf is also developing in Maryland and planning a second New York site at Lansing.

Kentucky is where it has bought most heavily. In February 2026 it paid $200 million for a former aluminum processing site at Hawesville in Hancock County, 790 acres that Century Aluminum had operated from 1969 until 2022, and named it the Justified Data Campus.

On July 6, 2026 it announced that Anthropic had taken the campus on a twenty-year lease expected to produce around $19 billion of revenue, with initial capacity due in the second half of 2027, full operation by early 2028 and up to 401MW of IT capacity at completion. Chairman and chief executive Paul Prager called it "a long-duration revenue stream with one of the world's leading AI companies" that "validates our strategy".

The same announcement disclosed that TeraWulf was selling its entire 50.1 percent holding in the Abernathy joint venture in Texas, a 168MW campus formed with Fluidstack in October 2025, to an investor group led by Fluidstack, which the company said let it recover the value of a $450 million investment and put the capital into assets it owns outright.

The second Kentucky site is the one that brought people out. Announced in late May 2026 and bought from Industrial Equity Partners, the Muskie Data Campus covers about 285 acres inside the 1,000-acre EastPark Industrial Park near Ashland and Grayson, on land already zoned for data center use, with an initial 500MW to ramp from the second half of 2028 and another 500MW targeted for the second half of 2030.

Prager described the purchase in terms of scarcity, saying "the defining constraint in this market is no longer computing hardware" but power, transmission infrastructure and execution certainty. EastPark is jointly owned by the Boyd, Carter, Elliott, Greenup and Lawrence county governments together with the Commonwealth of Kentucky, was established in 1988 on ground much of which had been strip mined, and is the same park from which the state had to claw back a $15 million investment when the Braidy Industries aluminum mill failed.

Days after the announcement, on June 1, 2026, Boyd County residents filled the county's convention and arts center for a three-hour town hall, livestreamed on Facebook, with the local judge-executives on stage taking questions. Nearly everyone who spoke ranged from doubt about the economics to flat opposition, and much of the anger was about the non-disclosure agreements local officials had signed with the developer.

David Sparrow, who lives along the Greenup-Carter county line, asked who had signed one, and a few people on stage put their hands up. "You're starting it off shady," he said. "We can't trust that. At least that's the way I feel now." He was not arguing the technology away: "I understand that AI is inevitable, I get that. But why are we doing it in a way that doesn't let the citizens speak for what they want?"

Aggy Vanderpool, who teaches environmental science at Lawrence County High School, pressed on the closed-loop cooling the company had described: "If the Muskie center development has been so carefully planned out, I'm curious as to why that basic information has not been made available to the public. Where is the water to initially fill these systems going to come from?"

Boyd County Judge-Executive Eric Chaney, who backed the project alongside Greenup County's Bobby Hall, apologized for how the announcement had been handled, said signing NDAs had "never crossed" his mind as wrong, and told the room to file open records requests. "I don't want to do anything in my life to be distrustful or to lose that trust from anybody in this room, whether you like me or not," he said.

He acknowledged that data centers elsewhere had pushed up electricity rates and drained water supplies, but said Kentucky Power's rules for large load customers protected other ratepayers. He also put the case for taking the risk, in a park he said had spent most of its existence chasing "ghost promises that have stained our community": "For all of us in this room, whether you support this project or you're against it, it's risk. Because risk brings change."

Hall, speaking over jeering, said that "if only one job is created, that's one more job than we had". Not everyone was against it; Greenup County property valuation administrator Tony Quillen compared the decision to Kentucky's bet on the Toyota plant at Georgetown decades ago, saying: "We took a chance then and look at Georgetown today."

The last speaker, Rachel Wilson of Boyd County, set it against the coal cycle: "Most of that memory is boom and then bust, so you want us to get excited about a boom. We're all concerned about how much that boom is going to cost us, and when is it going to bust, and who's going to pay for that bust."
