xAI appears to have assembled a massive battery at its Memphis data center complex. Canary Media reports that the grounds of the Colossus 2 facility contain 720 Tesla Megapack battery containers, which would make it potentially the largest battery installation in the United States.
The exact capacity is unknown. Canary Media could not confirm the figure with xAI, and the company has not publicly specified the size or role of the battery. Still, the presence of hundreds of Megapacks signals a major investment in on-site energy storage.
The battery sits at the center of a controversial AI computing hub in Memphis, where concerns about power demand and emissions have surrounded the facility. Adding large-scale storage could help xAI manage electricity use, but without official details or independent confirmation, the full impact remains unclear.
