Just a few weeks after Tesla fully opened the world’s largest Supercharging Oasis (164 stalls) in Lost Hills, California, a plan for an even larger hub emerged. Once completed, it will exceed 300 stalls, eclipsing all other Supercharging sites.

Firebaugh Supercharger

According to permit filings discovered by MarcoRP (@MarcoRPi1 / X), Tesla plans to significantly expand its existing Supercharging location in Firebaugh, California, near Interstate 5.

The station features 56 V3 Superchargers (capable of delivering up to 250 kW per stall). The document reveals a conditional use permit for an additional 232 Supercharging stalls, which would bring the total to 288. According to MarcoRP, most of the new stalls will be the “true” V4 stalls (rated at up to 500 kW). The first “true” V4 site was launched in September 2025.

On top of that, there will be 16 pull-through stalls for trucks. These stalls most likely will offer a 1.2 MW (1,200 kW) peak power output per stall for the Tesla Semi, using the Megawatt Charging System (MCS) connector.

A massive new Supercharger expansion is coming soon to Firebaugh, California!!

Last month, Tesla was granted a conditional use permit for the addition of 232 stalls in the agricultural lots north of the existing site.

Deploying 288 Superchargers in one location (304 stalls, including Megachargers) would make the Firebaugh location the world’s largest Tesla Supercharger station.

Drive Tesla Canada noted that the Firebaugh location was already the world’s largest Tesla Supercharger when it originally opened in 2020, with 56 stalls. This would be a nice comeback.

It’s worth noting that the upgraded station will not only have several times as many charging stalls but also twice the peak power (500 kW versus 250 kW for cars). These two factors combined could increase daily throughput by an order of magnitude.

The final question is when the plan will materialize.
