Opposition and litigation at this site
Nothing on record as of September 10, 2026. No lawsuit, organized opposition, or contested hearing over Savannah River Site AI Data Center (Amentum) in Barnwell County, South Carolina appears in the sources this registry tracks. That is an absence in our sources rather than a finding that none exists, and local opposition often predates any coverage a national dataset would pick up.
If you live near this site and something is happening that this page does not show, that is worth telling us. Send us the document and it goes in the record with the source attached. For sites where opposition is already established, see every contested site we track.
Notes on the record
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.
What the record does not establish, and the document that would
In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.
- Cooling method and water use
- Tax abatements or other public subsidy
- Permanent jobs promised
- Land area
- How the community has received it
- Which utility serves it
Which document closes each gap
- Cooling method and water use
- The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
- Tax abatements or other public subsidy
- The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
- Permanent jobs promised
- The economic development application or incentive agreement, which usually states a job commitment and a clawback.
- Land area
- The rezoning application, the plat, or the deed recorded with the county.
- How the community has received it
- Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.
- Which utility serves it
- The electric service agreement or the utility's filing with the state public utility commission.

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
