What the source record says
NNSA (DOE) announced 2026-07-20 that Amentum was selected to enter negotiations for a phased lease to build a ~1 GW AI data center at the Savannah River Site, paired with ~2 GW of dedicated on-site generation (companion record: srs-energy-generation-savannah-river-site-sc). SRS spans Aiken, Barnwell, and Allendale counties, SC; NNSA has identified 10 candidate tracts within the site but has not publicly designated a specific tract, county, or parcel. Coordinates are the SRS site centroid, not a specific tract — precision approximate. Selection for negotiation is NOT a final lease award; subject to successful negotiation, permitting, and federal safety/security review.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
