Colossus is the name used for a cluster of data centers developed by xAI (later SpaceXAI) in the Memphis, Tennessee–Southaven, Mississippi area. The original facility, Colossus 1, began construction in 2024 at a former Electrolux plant in South Memphis and became operational in July–September 2024. Its primary purpose was to train the company's chatbot Grok; it also supported other projects associated with Elon Musk, including the social network X and SpaceX. ↑ Skidmore, Zachary (May 22, 2025).

"xAI Adds 19 New Gas Turbines Despite Ongoing Lawsuit". In February 2025 an xAI affiliate purchased a large warehouse and adjacent parcels at 5420 Tulane Road (Whitehaven, Memphis) for roughly $80 million. This became the core of Colossus 2 (branded Macrohard on the rooftop). Colossus 1 was built at the former Electrolux factory (3231 Paul R. Lowry Road / Riverport area) in South Memphis. The abandoned industrial building allowed rapid conversion. Construction of the initial cluster of approximately 100,000 Nvidia H100 GPUs was completed in 122 days; the system went live in mid-to-late 2024. Capacity was later expanded to include H200 and early B200 GPUs. Partners included Dell Technologies and Supermicro. Because the local grid connection was initially limited (~8 MW, later upgraded toward 150 MW), xAI deployed temporary natural-gas turbines and Tesla Megapack battery systems.

Elon Musk’s xAI datacenter generating extra electricity illegally, ...

The xAI datacenter in Memphis. Photograph: Steve Jones/Flight by Southwings for Southern Environmental Law Center ... Win for Memphis activists who say ‘Colossus’ facilities add extra pollution to already overburdened communities ... A US regulator ruled on Thursday that Elon Musk’s artificial intelligence company had acted illegally by using dozens of methane gas turbines to power huge datacenters in Tennessee. At full capacity, xAI’s Colossus 1 datacenter uses 150 megawatts of electricity – enough power to run 100,000 homes – and the company plans to expand. Musk set up Colossus 1 in just 122 days during the summer of 2024, record time for getting a datacenter up and running. Colossus 2, which is even bigger at 1m-square-feet, went under construction last year and is located on the border of Memphis in Southaven, Mississippi. At one point, up to 35 of these generators were powering Colossus 1. xAI eventually received permits for 15 turbines at Colossus 1 and is now operating 12 permitted machines at the site. Under the EPA’s new ruling, the permitting for these turbines would fall under federal law. It is unclear how or whether the government will penalize companies who are not in compliance. The EPA spokesperson did not respond to the Guardian’s questions about enforcement. The ruling is a win for community activists in Memphis who have been battling xAI’s use of the portable turbines as long as the generators have been in use. In a post on X, Musk said this supercomputer was named “MACROHARDRR” and would need nearly 2 gigawatts of computing power. Colossus 2 also is also powered by dozens of gas turbines. According to Mississippi Today, the datacenter has 59 generators; 18 of those are considered to be temporary and do not have air quality permits. ... Amanda Garcia, a senior attorney with the Southern Environmental Law Center, which filed the intent to sue xAI alongside the NAACP, said the EPA ruling “makes it clear that companies are not – and have never been – allowed to build and operate methane gas turbines without a permit and that there is no loophole that would allow corporations to set up unpermitted power plants”.
