Tesla has just flipped the switch on its most ambitious charging site yet and it’s entirely off-grid. The new Supercharger station in Lost Hills, California, now stands as the largest in the world with a staggering 168 stalls. More than just size, it’s a proof of concept: fast, solar-powered charging without relying on the local utility grid.
Tesla Supercharger station uses solar and Megapacks only

This station didn’t wait around for grid connections. Powered entirely by solar panels and 10 Megapack battery units, the site delivers up to 11 MW of solar energy, backed by 39 MWh of stored capacity. Half the chargers were already live in time for July 4th road trips, and the rest went active just in time for Thanksgiving.
Despite its massive scale, the only utility connection is a small one, intended for future upgrades not current use. Tesla bypassed the wait for utility approval by going off-grid from day one, giving it a serious edge in deployment speed.
Tesla Supercharger station adds trailer-friendly stalls
Tesla didn’t just focus on volume, it added utility. Among the 168 stalls are 12 pull-through spaces designed specifically for towing vehicles. These stalls let drivers charge their trailers without unhitching, a rare but needed feature in EV infrastructure.
Here’s what sets the site apart:
- 168 total Supercharger stalls
- 12 pull-through trailer charging bays
- 10 Megapacks supplying 11 MW solar energy
- Built and activated in just eight months
- No reliance on local power grid
Speed, scale, and solar: Tesla’s charging edge grows
Tesla used prefabricated chargers and an innovative no-pour foundation to speed things up. This cuts down both time and cost, giving Tesla a big advantage when bidding for public charging grants. As charging demand climbs, especially around holidays, this off-grid megastation might just be a sign of where things are headed.
No grid, no problem, Tesla builds faster than the waitlist
Tesla’s record-breaking Supercharger site doesn’t just show what’s possible; it exposes how slow traditional infrastructure can be. With solar, Megapacks, and streamlined construction, the company is charging ahead while others are still stuck in planning.
