This is a source-attributed discovery row. It can help you find a place and its citations; it is not a DataCenterData finding that the facility is distinct or currently operating.
This row and xai-macrohardrr-southaven-ms describe the same 2400 Stateline Road West warehouse. It remains available under its stable directory ID but is withheld from map and activity counts to avoid double counting. The licensed source row and its citations remain available here.

The stored 2,000 MW figure describes combined regional xAI compute capacity rather than capacity of this Southaven building. The upstream row remains attributed below, but this value is not repeated as site capacity.

Provider notes
Energy. Private behind-the-meter gas-turbine plant at a former Duke Energy site powering Colossus 2. MS DEQ permitted 41 turbines (~1.2 GW ceiling, Mar 2026); ~495 MW tied to 27 disclosed turbines, up to 59 reportedly run pre-permit. Subject to NAACP/SELC/Earthjustice litigation over unpermitted operation.
Water. The City of Southaven addresses water supply but not the heat-rejection method: xAI is described as a metered municipal customer under "strict capacity management" with its own recycling solutions planned. No source fetched this run identifies evaporative, closed-loop or dry cooling, so coolingType stays unknown rather than being inferred from the liquid-cooled GB300 racks (rack-level cooling is heat CAPTURE, not heat rejection).
Community. Safe and Sound Coalition (lifelong residents) cited lack of transparency; NAACP raised environmental concerns about pollution affecting Southaven and neighboring Memphis communities; residents allege public was not consulted prior to expansion.
These reviews flag conflicting scope, inconsistent source text or support that has not been established. A withheld value may appear in the explanation, but is not displayed as an established field. The upstream row remains attributed under Sources.
- Announced investment: The source note says the $20 billion figure covers xAI’s total Mississippi commitments, including the adjacent power-plant site, not only this building.
What the source record says
Address: 2400 Stateline Road, Southaven, MS 38671 (near Tennessee border); coordinates are approximate for that address. The $20B investment figure covers total xAI Mississippi commitments including adjacent power plant site, not only this building. Facility is distinct from the already-tracked Colossus supercomputer clusters in Memphis, TN. Combined with Memphis facilities, xAI aims for nearly 2 GW total compute capacity. Fix: jobs.sourceIndex corrected from 0 to 1; the specific 145-person figure is reported by Mississippi Free Press (source 1), not the governor's press release (source 0) which states only 'hundreds of permanent jobs.'
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.
