Tesla Megapack Batteries to Power xAI Colossus Supercomputer in Memphis
The collaboration between Tesla and xAI continues to showcase the synergy among Elon Musk’s ventures, with Tesla Megapack batteries being utilized to power the xAI Colossus supercomputer in Memphis. This partnership aims to ensure power stability and reliability for the facility, highlighting the integration of innovative energy solutions in the tech industry.
Recently, the Greater Memphis Chamber announced that Colossus has been connected to a new 150-megawatt electric substation as part of its first construction phase. This move not only enhances the facility’s capacity but also addresses concerns raised by environmental justice groups regarding the initial use of natural gas turbines.
According to the Chamber, the temporary natural gas turbines that were previously powering the Phase I GPUs are being replaced by Tesla Megapacks. These Megapacks will manage outages and demand surges, improving the facility’s reliability and reducing its environmental footprint.
As xAI continues to rapidly develop Colossus to advance AI capabilities, the shift to Megapacks and grid power reflects a commitment to sustainability and operational continuity. By leveraging Tesla’s energy solutions, xAI aims to mitigate environmental impacts while driving innovation in the AI space.
The deployment of Megapacks also underscores the collaboration among Musk’s various companies, including Tesla, SpaceX, Neuralink, and The Boring Company. This interconnected business ecosystem is exemplified by Tesla’s significant year-over-year growth in energy deployments and its plans to establish a new Megapack factory in Texas.
Tesla Energy reported a 156% increase in deployments in Q1 2025, highlighting the growing demand for energy storage solutions. The integration of Megapacks in powering Colossus not only enhances operational stability but also sets the stage for broader technological advancements and economic impacts.
