Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.

Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.

Source notes

xAI did not obtain a PILOT or any other formally granted incentive for the Memphis site, unlike the usual Memphis path, so no subsidy is recorded, as a known absence rather than an unknown; the site is instead expected to pay more than $30 million in combined Memphis and Shelby County property taxes. A federal Clean Air Act suit filed 2026-04-14 (NAACP v. X.AI Corp. and MZX Tech LLC, No. 3:26-cv-00074, N.D. Miss.) targets xAI's separate 'Colossus Gas Plant' in Southaven, Mississippi (MZX Tech LLC, 2875 Stanton Road South), not this site or CTC Property LLC; it cites this site's turbine history only as background. Permit-level detail for this site's turbines, including that the permit covers 15 turbines on a permanent basis, is in the companion record CTC Property Gas Turbine Plant (Colossus 1).

About 35 on-site natural-gas turbines (a combined 422 MW per SELC and aerial imagery) supplement a 150 MW grid substation and Tesla Megapack storage. The Shelby County Health Department permitted only 15 turbines; the SELC/NAACP/Young, Gifted & Green appeal of that permit was dismissed as moot by the Memphis and Shelby County Air Pollution Control Board on a 6-1 vote on 2025-12-15 (after the health department and xAI argued most turbines had been removed), ending the appeal-triggered stay and leaving the permit in force; press at the time reported 12 SCR-equipped turbines still active and a permit expiring 2027-01-02. TVA's board voted unanimously on 2026-02-11 to approve an additional 150 MW of firm power, which would double the approved grid allocation to about 300 MW; that approval is contingent on contractual, financial and operational requirements and is a ceiling, not delivered power — as of 2026-09-23 no source reports the second increment energized, and the site is still described as taking 150 MW from the grid. xAI said the Phase-I temporary turbines would be demobilized after grid connection, but 2025 aerial imagery shows 35 on site.
