Tesla has officially unveiled its “Oasis” Supercharger station in Lost Hills, California, combining massive solar generation and battery storage to deliver a fully off‑grid EV charging solution. The first phase, launched just in time for the July 4 holiday weekend, features 84 operational V4 Supercharger stalls out of a planned 168.
Spanning 30 acres, the facility includes 11 MW of ground‑mounted and canopy solar panels, generating enough power to feed the station and charge vehicles independently of the electrical grid. This renewable energy output is backed up by ten Tesla Megapacks, delivering 39 MWh of storage—sufficient to charge roughly 1,000 EVs per day under ideal conditions.
Tesla’s approach at Oasis marks a major milestone in its long-awaited commitment to sustainable charging infrastructure. While Elon Musk first pledged to power Superchargers with solar and batteries nearly a decade ago, widespread adoption lagged—until now. Oasis represents a significant progression, showcasing how solar and storage can support large‑scale EV charging.
The station is connected to a 1.5‑MW grid connection, but Tesla currently runs Oasis entirely off‑grid. The modular combination of solar, storage, and V4 Superchargers enables load‑shifting and peak shaving, reducing strain on traditional utilities.
Construction began in October 2024, and Tesla completed the first phase in just eight months. The next stage will bring the remaining 84 stalls online, as well as a driver lounge, slated to open before the end of 2025.
Despite the milestone, Tesla and the broader EV industry may face headwinds from recent federal policy changes. A new Republican-backed bill limits solar and energy‑storage incentives while penalizing such infrastructure—potentially jeopardizing further Oasis‑style deployments.
