SpaceX Turns to Tesla Megapacks to Power AI Data Centers

SpaceX significantly increased its procurement of Tesla Megapack battery systems in the second quarter of the year, deploying the large-scale energy storage units to support its Colossus artificial intelligence data centers located in the Greater Memphis area. The move underscores a growing strategic relationship between two of Elon Musk's most prominent ventures, with each supplying critical infrastructure to the other.

Megapacks are Tesla's industrial-grade battery storage product, designed to store and dispatch electricity at the utility scale. Their use in data center applications reflects a broader industry push to stabilize power supply for AI workloads, which demand consistent, high-density electricity that grid fluctuations alone cannot reliably provide. By deploying backup battery reserves, SpaceX can insulate its compute operations from outages or demand-surge disruptions.

The Colossus facility in Tennessee represents SpaceX's ambition to build serious AI computing capacity outside of traditional Silicon Valley corridors. Memphis and its surrounding region offer land availability and proximity to power infrastructure, factors that have made the mid-South an increasingly attractive destination for hyperscale data investment. The reliance on Megapacks signals that energy resilience, not just raw compute capacity, is a top engineering priority for the project.

The cross-company transaction also raises familiar questions about the financial and governance entanglements that arise when a single executive — in this case Musk — oversees multiple large enterprises that do business with one another. Whether those arrangements reflect genuine market competitiveness or internal preference is a question that analysts and investors in both companies will likely continue to scrutinize.
