The Energy Department unveiled a $100 billion private-sector plan to convert a Cold War uranium plant in western Kentucky into an AI computing campus, testing whether massive infrastructure bets can still attract capital after the Stargate venture stalled.

The Paducah blueprint

Brookfield Asset Management will construct a 1.8-gigawatt data center campus for artificial intelligence and high-performance computing, while NextEra Energy builds two gigawatts of natural gas generation paired with 2.6 gigawatts of battery storage. The phased buildout targets completion by 2032 and is projected to generate roughly 8,000 construction roles and 600 permanent operating positions. Power will run on dedicated supplies designed to feed surplus electricity back to the regional grid, a structure intended to shield local ratepayers from cost increases. A closed-loop cooling system will recirculate water continuously, a sharp contrast to the site’s previous occupant, the Paducah Gaseous Diffusion Plant, which was engineered to draw up to 30 million gallons daily from the Ohio River.

The Stargate shadow

The announcement arrives as investor appetite for concentrated AI infrastructure wobbles. Last year, a coalition including Oracle, OpenAI, and SoftBank launched Stargate, a $500 billion four-year program to build hyper-scale campuses across the United States, starting in Abilene, Texas. By January, JPMorgan Chase was struggling to syndicate $38 billion in construction debt for the initiative, with banks spending more than six months trying to place the paper. Buyers balked at the single-tenant risk tied to Oracle leases, and S&P downgraded Oracle to BBB- in July, citing data center spending. The debt ultimately sold at a discount. In April, OpenAI paused its UK Stargate arm, planned with Nvidia and Nscale to deploy up to 31,000 GPUs across northeast England, citing high industrial power prices and regulatory uncertainty. Development will resume only when the "right conditions" return for long-term infrastructure investment.

What the market is pricing

The Paducah deal differs in structure: Brookfield and NextEra are building generation alongside compute, and the grid-export design attempts to socialize less risk onto ratepayers. But the scale, $100 billion in committed private capital, still requires debt markets to absorb significant exposure to a single AI campus. Whether lenders treat this as a diversified energy play or another concentrated tech bet will determine the cost of capital for the next phase.

The grid question

Two gigawatts of gas plus 2.6 gigawatts of storage represents a substantial generation buildout in its own right. If the campus operates as designed, excess power flows back to the grid during off-peak compute hours, effectively using AI demand to underwrite baseload capacity. That model only works if utilization rates hold and if the battery economics pencil out at current storage costs, assumptions that remain untested at this magnitude.
