The US Department of Energy has selected Amentum to develop a 1 gigawatt data center and 2 gigawatts of on-site energy generation at the Savannah River Site in South Carolina, with power initially from natural gas transitioning to nuclear. The project aims to build federal AI infrastructure without burdening utility ratepayers, though the final lease agreement and timeline remain undetermined.
This Wire brief sits within Fusion42's coverage of AI Infrastructure and Cloud Infrastructure.
◆ ◆ The Wire takeaway
If you build power systems, cooling, or networking for data centres, the federal government just committed to a 3-gigawatt site at Savannah River and three others like it — and Amentum now needs to buy components at scale. This is the infrastructure supply chain rewiring itself around US AI policy, not a one-off contract.
