Tesla plans to build the world’s largest Supercharger station with 304 stalls, including 16 for Tesla Semis, in Firebaugh, California.
Tesla plans to expand its existing Supercharger site in Firebaugh, California, into the world’s largest with a total of 304 stalls — 288 for passenger vehicles and 16 dedicated for Tesla Semis — once complete.
This represents an 85% increase over Tesla’s current largest site (164 stalls at Oasis in Lost Hills, California). The project, approved via a conditional use permit last month, adds 232 new car stalls to the existing 56 (some sources note the current count as around 72, but the core expansion figure holds). It includes a separate area for Semi operations with its own access routes, plus an amenity building and outdoor seating primarily for truck drivers.
Here are examples of large-scale Tesla Supercharger sites for context:
Firebaugh sits along Interstate 5, a key corridor connecting Southern California ports to Central Valley and Bay Area distribution hubs. This strategic spot has made it a priority since the original site opened in 2020 as Tesla’s then-largest in the US with 56 stalls.
Why Firebaugh and why now
The expansion reflects long-term planning by Tesla’s charging team, coordinated with local utilities and jurisdictions. It accounts for forecasted EV adoption growth, with built-in flexibility to adjust pace based on real demand.
A Tesla Charging team member with years of experience emphasized this deliberate approach.
Here is the post from Tesla’s Max DeZegher, who has been building Superchargers since 2014:
The site’s location supports both consumer travel and commercial trucking, especially as Tesla ramps up the Semi program. Dedicated Megachargers for Semis signal confidence in heavy-duty electric transport along this major freight route.
Reactions from Tesla enthusiasts and observers
Enthusiasts and Tesla-focused accounts quickly highlighted the scale as a bold step in infrastructure for EVs and trucking.

So what
This move positions Tesla far ahead in high-capacity charging, especially as more non-Tesla EVs gain access to Superchargers and Semi deployments increase. It underscores the company’s commitment to scaling ahead of demand along critical corridors, potentially reducing wait times and supporting broader EV and electric trucking adoption in California and beyond.
Firebaugh’s rural setting along I-5 provides ample space for this growth.
