Tesla has officially completed and fully activated what is now the largest Supercharger station in the world, located in Lost Hills, California, along one of North America’s busiest long-distance travel corridors.
After first opening with limited capacity earlier this year, Tesla confirmed this week that all stalls are now online and operational, making the site a flagship example of the company’s solar-powered, off-grid charging future.
Tesla shared the update through its official Tesla Charging account on X, saying: “All Superchargers now operational. Safe Thanksgiving travels!”

A Massive Charging Hub on I-5
The Lost Hills Supercharger sits between San Francisco and Los Angeles, serving one of the most heavily trafficked EV corridors in the world along Interstate 5.
The completed site features:
- 164 Supercharger stalls total
- 12 pull-through stalls for vehicles towing trailers
- 11 MW of solar capacity (ground-mounted plus solar canopies)
- 10 Tesla Megapacks providing 39 MWh of battery storage
Covering over 30 acres, the station operates completely off-grid, relying solely on solar power and energy stored in its massive Megapack system.
When the site first partially opened on July 4, only 84 stalls were live, but Tesla informed drivers at the time that the rest would follow later in the year. Now, that promise has been fully delivered.
Powered by Solar and Megapack Storage
What makes Lost Hills truly different from any Supercharger before it is its independence from the utility grid.
The on-site solar installation generates electricity during the day, while the 10 Tesla Megapacks store excess energy to provide reliable charging even at night or during peak usage hours. In total, the battery system can hold 39 MWh, enough to support high traffic without pulling power from the local grid.
Built at Record Speed
Despite the project’s scale, Tesla managed to build it in just over one year from breaking ground, also opening the first phase after just eight months, a remarkable timeline for an energy installation of this size.
Tesla has already hinted that similar solar-powered Supercharger “oasis” sites could appear in other high-traffic regions in the future, potentially expanding this model into other markets where grid capacity remains a challenge.
