Tesla’s New 164-Stall Supercharger in California Runs Fully on Solar Power

Tesla just flipped the switch on the largest Supercharger station in the world. The new site sits in Lost Hills, California, right off I-5 between Los Angeles and San Francisco. Anyone who has taken that drive knows how busy this stretch gets, especially during long weekends. Now EV drivers have a charging hub built for real highway traffic.

Tesla confirmed the full launch through its official charging account on X, telling drivers:

“All Superchargers now operational. Safe Thanksgiving travels!”

The scale of this site is in a different league. It covers more than 30 acres and includes 164 Supercharger stalls, which already sets it apart from anything Tesla has built before. There are also 12 pull-through stalls built for trucks and trailers, a nice touch for drivers hauling toys or gear. The energy backbone is even more impressive. The site runs entirely on an 11-megawatt solar system paired with 10 Tesla Megapacks. Those battery units store 39 megawatt-hours of energy, which is enough to keep the station running through nights, cloudy stretches, and peak holiday usage without taking a single watt from the grid.

What makes this build interesting is how self-sufficient it is. Most fast-charging hubs depend on the local utility, which often leads to delays, capped power, or expensive upgrades. Lost Hills avoids all of that. The solar array feeds the site during the day, and the Megapacks take over when the sun drops. It’s basically a closed-loop system designed to stay online regardless of local grid constraints. This setup previews Tesla’s long-term goal of building high-traffic charging sites without adding strain to aging infrastructure.

The construction timeline is another part of the story. Tesla built the entire facility in just over a year and opened the first phase after only eight months. For a project of this scale, covering dozens of acres, connecting more than a hundred charging stalls, and installing a utility-scale energy system, that pace is rare.

For EV owners, Lost Hills signals a shift in how the next generation of charging stations will look and operate. These sites aren’t just rows of chargers anymore. They’re energy hubs with their own solar, their own batteries, and the ability to handle the kind of traffic that used to overwhelm earlier stations. It’s a model that works well in remote highways, regions with weak grid access, and popular travel corridors where thousands of EVs pass through every day.

Tesla hinted that Lost Hills is only the prototype. Similar solar-powered sites are already being discussed for other high-demand areas, and as EV adoption grows, building more off-grid stations like this could take pressure off utility companies and give drivers more confidence during long trips.
