Savannah River Site AI data center and energy campus (Amentum / DC BLOX)

Savannah River Site AI data center and energy campus (Amentum / DC BLOX) is an announced data center project in Aiken County, SC, backed by Amentum-led consortium with DC BLOX (DOE/NNSA site). The project is sized at 1,000 MW. On July 20, 2026 the DOE National Nuclear Security Administration selected an Amentum-led consortium including DC BLOX to develop a behind-the-meter AI data center with integrated on-site generation at the Savannah River Site, one of four federal AI data center sites. Reports cite ~1 GW of data center load with up to 2 GW generated on site (initially natural gas, later nuclear). Lease negotiations commenced after the award; no construction timeline released.
