Tesla is planning for a new 300+ stall Supercharger station that will be an expansion of an existing facility, and the company is planning to add a surprise for the Semi.
The Firebaugh, California Supercharger is currently 72 Superchargers, but Tesla filed for an expansion that will add 232 additional plugs for passenger vehicles, and it also plans to add 16 Semichargers.
This will be the biggest Supercharger station Tesla will have to date, just months after it finished the Supercharger Oasis in Lost Hills, California, which has 168 stalls. This will have 304 total Supercharger stalls, and then the additional 16 Megachargers.

Absolutely INSANE size
This is located on I-5, so many semis will be traveling along this route

The Firebaugh Supercharger is located on I-5, which is a major reason for why Tesla has chosen the location for additional Megacharger plug-ins, as Tesla Semi Program Manager Dan Priestley said on X earlier today.
Lots of trucks to electrify on I-5

The project was revealed by MarcoRP, a Supercharger tracker.
The expansion is a massive signal for charging demand, especially as Tesla’s Superchargers are opened to numerous automakers and are no longer exclusive to the company’s EVs. Additionally, the installation of Megachargers is a good sign to come for the Tesla Semi program, which aims to truly ramp up this year.
Tesla plans to launch production of the Semi later this year.
It could also mean Tesla is going to expand its footprint of large-scale Supercharger projects in the coming years, which would be a big boost as EV adoption continues to soar in the United States.
