The record, newest first

  1. TDLR registration DA12-2 lists a $293.7 million fit-out of the first two floors (158,293 square feet), scheduled from September 2027 to March 2028. (Texas Department of Licensing and Regulation, Nov. 21, 2025)

  2. TDLR registration DA12-1 lists a four-story data center with 20 generators, estimated at $542.8 million, with work scheduled from Feb. 19, 2026, to Oct. 12, 2027. (Texas Department of Licensing and Regulation, Nov. 19, 2025)

Conflicts and open questions

  • No source reviewed states the power capacity.
  • The TDLR owner is listed as 'DA12' with an address at 1 Lagoon Drive, Redwood City, Calif., Equinix's headquarters; Equinix's own DA12 page could not be opened, so the developer attribution rests on that address and the DA naming.
  • The scope of DA12-1 includes 20 generators and five generator pads.
