In a new video posted to X, Tesla is showing the progress of its first Lithium Iron Phosphate (LFP) cell manufacturing factory in North America. The facility, located in Sparks, Nevada, will be used to produce LFP battery cells for Megapacks and Powerwall.
However, the implications of this new factory extend beyond Tesla Energy. By on-shoring the production of these cost-effective batteries, Tesla is not only securing its energy supply chain but also opening the door to potentially reintroducing LFP-based vehicles in North America.
Megapack First
The immediate beneficiary of the new Nevada LFP facility is Tesla’s Energy division. LFP chemistry is ideal for stationary storage products like Megapack and Powerwall. It offers a very long life cycle, is extremely thermally stable and safe, and is significantly cheaper to produce than nickel-based batteries, partly because it contains no cobalt.
Until now, Tesla has relied on suppliers like CATL in China for these cells. A dedicated, domestic supply will enable Tesla to dramatically ramp up Megapack production to meet North America’s increasing demand for grid-scale energy. On the other hand, Megafactory Shanghai continues to utilize CATL’s LFP batteries and will support the rest of the world.
Tesla first revealed that they were planning to onshore LFP production in North America at the Q1 2025 Earnings Call, which will help them avoid costs, innovate in new technology, and insulate themselves from geopolitical supply chain risks.
A Potential Return for LFP Vehicles?
Another exciting application for Tesla is what this new factory means for Tesla’s budget-oriented lineup. For years, Tesla has been constrained in its ability to offer LFP-based vehicles in North America. While LFP packs are used in other markets for specific standard-range RWD vehicles, tariffs on important Chinese cells made it difficult to import these cells for use in North America.
With a domestic supply of LFP cells produced in Nevada, this tariff-related barrier will be mostly eliminated, pending the sourcing of lithium from a North American site. This is likely to lead to the reintroduction of LFP-based vehicles to the North American market, possibly in late 2026 or 2027.
An American-made LFP pack could lead to a more affordable base Model 3 or Model Y, or potentially help Tesla cut costs on the next-generation Affordable Model even further. This helps to give customers a lower-cost entry point without sacrificing a lot of range, and with the added benefit of being able to regularly charge to 100%.
Mega Nevada
With Mega Nevada now progressing well, Tesla is in an excellent position to continue iterating on its vertical integration and scaling Megapack and Powerwall—two of Tesla’s fastest-growing businesses—further. There are tons of benefits for consumers in the future as Tesla continues down this path, with more affordable Powerwalls for the home, cheaper electricity prices thanks to grid-forming Megapacks, and cheaper LFP vehicles.
