Amentum Lands DOE Deal for $1GW AI Data Center at Savannah River Site
Event summary
- Amentum selected by DOE's NNSA for phased lease to develop a 1-gigawatt AI data center at Savannah River Site, South Carolina.
- Project includes ~2 gigawatts of on-site energy generation, initially powered by natural gas transitioning to advanced nuclear.
- Deal underscores intersection of AI computing, energy resilience, and national security infrastructure.
- Amentum's expertise in nuclear operations and public-private partnerships cited as key differentiators.
The big picture
This deal marks a strategic pivot in government-backed AI infrastructure, blending computing power with domestic energy security. The project's scale—1GW data center paired with 2GW generation—positions Amentum as a key player in the emerging nexus of AI and resilient energy systems. Similar public-private partnerships are likely to emerge as demand for secure, high-capacity computing grows.
