Analysis
The US Department of Energy is converting a Cold War-era uranium enrichment site in Kentucky into a $100 billion data-center complex that will include its own new natural gas and battery storage power plant, tapping private capital to fund the buildout. The move follows a related DOE decision earlier in July to have engineering contractor Amentum negotiate a lease to develop an AI data center and on-site power plant at South Carolina's Savannah River Site -- another legacy federal nuclear facility.
The pattern is becoming a deliberate federal strategy: repurpose decommissioned or underused nuclear real estate, where power infrastructure, security clearances and environmental permitting are often already partially in place, rather than fighting multi-year permitting battles for greenfield AI data-center sites. Every major hyperscaler has now signed at least one nuclear power deal in 2026 -- commitments that together add up to nearly 10 gigawatts of capacity, enough to power roughly 7 million homes -- including Microsoft's $16 billion, 20-year deal for the Three Mile Island Unit 1 restart and Amazon's $700 million investment in X-energy for small modular reactors.
“Private equity funding for the Kentucky site suggests the government sees this as a repeatable template rather than a one-off.”
What makes the federal-site strategy notable is that it is succeeding at something the US utility industry and government had failed to do for 40 years: making new nuclear and gas generation commercially bankable again, purely because AI data-center demand now justifies the capital cost that standalone power projects never could on their own. Private equity funding for the Kentucky site suggests the government sees this as a repeatable template rather than a one-off.
For infrastructure investors and founders in the AI-power space, federal nuclear real estate reuse represents one of the fastest paths to gigawatt-scale power for AI workloads currently available in the US, sidestepping years of new-site permitting fights that continue to slow greenfield projects like Crusoe's Texas campuses. The bear case is execution risk on projects this large and this novel: repurposing Cold War-era nuclear infrastructure for commercial data centers involves environmental remediation, security transitions and regulatory approvals that have no close historical precedent to model timelines against. What to watch: whether the Kentucky project's private financing closes on schedule, and whether additional DOE sites get identified for the same treatment.
