Opposition and litigation at this site

Nothing on record as of October 28, 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.

Power and water

About 2 GW of on-site generation, initially natural gas, with plans to move to advanced nuclear. Lease is still in negotiation.

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: Savannah River Site Energy Generation Project (Amentum)). SRS spans Aiken, Barnwell, and Allendale counties, SC. NNSA's solicitation for the site identified 10 tracts totaling 3,103 acres for AI infrastructure projects; as of October 2026 none of the cited sources designates a specific tract, county, or parcel for this project. Coordinates are the SRS site centroid, not a specific tract, precision approximate. The county shown is the one containing that centroid (Barnwell County, per the US Census geocoder, October 2026); it is not a designated project county. 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.

Have one of these documents? Send it to us and we will add it to the record with attribution.

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.
