TeraWulf pays the freight for 482MW Kentucky grid connection

TeraWulf has won Kentucky Public Service Commission approval for a 482MW electrical service agreement, securing the grid connection for its Justified Data Campus in Hancock County. The approval, reported by Data Center Dynamics, gives the developer a permitted, existing interconnection for a campus anchored by Anthropic, the AI lab that signed on as a long-term tenant in July.

The retail electric service agreement puts the full cost of serving TeraWulf's load on the company: market, transmission, delivery, and other load-serving costs, plus customer-specific infrastructure costs and substantial credit-support obligations. It also includes negotiated demand adders and customer charges that deliver incremental payments to Big Rivers Electric Corporation and Kenergy Corp, the two rural cooperatives that will serve the site.

Justified occupies 790 acres that once held a Century Aluminum processing plant, operated from 1969 to 2022. The campus is sized at 480MW while the agreement covers 482MW of delivery, with the first facility due online in 2027. It will draw on an existing grid connection — what CEO Paul Prager called “a former industrial site with existing transmission infrastructure” that the company is putting “back to productive use at scale.”

Prager framed the commission's approval as validation of that model. “Power is the gating factor for AI infrastructure, but how you bring that power to market matters,” he said. “We're paying the costs associated with our load, protecting existing ratepayers, and making a significant long-term investment in Kentucky.”

That model is becoming the price of entry for data center development in rural power markets. As this publication has argued, the power-rights game has shifted from get-in-line to prove-you-can-build, and the Kentucky approval shows what proving it looks like in practice: a developer willing to write checks for the full grid cost of its load, plus a little extra for the host co-ops. The incremental payments to Big Rivers and Kenergy are the piece of the deal that matters most, turning the utility from a watchdog over ratepayer exposure into a financial participant in the project. That may clear more local hurdles than a tax abatement or a jobs promise, because it changes the default question from “what will this cost us?” to “how much do we get?”

TeraWulf intends to repeat the play. It acquired another Kentucky site in May for a 1GW data center, has development ongoing in Maryland, and is planning a second project in New York's Lansing. Each will need the same combination of transmission capacity and local acceptance, and each will have to find its own version of the bargain.

The timing helps. The market for digital infrastructure is eager for projects with power already under contract — Nscale's $3bn US IPO, covered here last week, is betting the $51bn backlog on a 10GW buildout. TeraWulf's approach to that constraint is more granular: buy the grid access one county at a time, and make sure the county gets paid.

The Kentucky commission's decision is a small green light, but it is the kind of green light that compounds. Interconnection approval is the rarest commodity in the data center industry, and TeraWulf now holds a 482MW block of it in a state that wants the jobs and has a cooperative utility structure ready to make the economics work. The next test is whether the same formula clears the 1GW site.
