SpaceXAI is building the world's largest integrated supercomputer at the Tennessee-Mississippi state line.
SpaceX announced today that it has acquired xAI.
The turbines, which will be installed at a former Duke Energy power plant site in Southaven, will be used to power xAI’s Colossus 2 data center, located a few hundred meters from Tulane Road, across the state boundary in the Whitehaven district of Memphis.
and the data center came online in January.
In addition, xAI owns a second large property on Tulane Road and has stated that its energy needs for that site exceed 1,000 megawatts.
xAI’s consultants submitted an air modeling protocol to EPA for an installation of 40 to 90 combustion turbines at the Tulane Road site.
After acquiring their second facility just north of the Mississippi state line, property in Southaven’s industrial zone became ideal for further expansion.
The company has two data centers — Colossus 1 and Colossus 2 — in Memphis, Tennessee, just across the Mississippi state line.
Elon Musk’s xAI filed a $659 million permit for expansion to its Colossus 2 site on Tulane Road.
