Tesla is gearing up for a major expansion of one of its key Supercharger sites in California, with plans in place to create what could soon be the largest Supercharger station in the world.
The company has recently been granted a conditional use permit to significantly grow its existing Supercharger location in Firebaugh, California. The proposed expansion includes the addition of 232 new charging stalls for cars and 16 dedicated Semi chargers, which would bring the total number of stalls at the site to an impressive 304 once the project is completed.
Currently, the Firebaugh site is equipped with 56 V3 Supercharger stalls that were first unveiled back in November 2020. With the approved expansion, the site will feature a total of 288 charging stalls for passenger vehicles, along with 16 designated Tesla Semi chargers. Additionally, an amenity area is expected to be incorporated into the expanded site, further solidifying Firebaugh’s position as a critical charging hub along California’s busy Interstate 5 corridor.
If the plans come to fruition, the upgraded Firebaugh Supercharger would surpass Tesla’s current largest Supercharger in the world — a 164-stall site in California that opened just a few months ago — by approximately 85%. It would also overshadow Tesla’s upcoming largest Canadian Supercharger, set to open later this month.
Although technical details have not been confirmed by Tesla yet, the expansion is likely to feature next-generation V4 Supercharger stalls. Tesla has been making V4 hardware standard for new installations as it continues to enhance its network to accommodate higher charging speeds, longer cables, and a wider range of vehicle types.
The timing of the expansion aligns with the significant growth of Tesla’s Supercharger network in 2025, which saw a record 6.7 TWh of energy delivered to EVs worldwide. The company has been expanding its charging network to accommodate other automakers, such as BMW, which recently gained access to Superchargers.
Given its central location, Firebaugh is a strategic choice for such a substantial buildout, especially as long-distance EV travel becomes more common and Tesla prepares for increased usage from both passenger vehicles and its upcoming Semi fleet. Once completed, this site has the potential to not only be Tesla’s largest but also one of the most vital EV charging hubs globally.
