Tesla Unveils World's Largest Off-Grid Supercharger in California, Powered by Solar and Megapack Storage
Key Insights
Tesla has opened the first phase of Project Oasis in Lost Hills, California, featuring 84 operational Supercharger stalls, with a total of 168 planned.
The site is currently 100% off-grid, drawing all its power from an 11 MW solar array and storing it in 10 Megapack battery units.
This self-sufficient charging station serves as a critical proof of concept for resilient, grid-independent EV infrastructure, reducing strain on local utilities.
The rapid eight-month construction timeframe highlights Tesla's efficient execution in deploying large-scale renewable energy and charging solutions.
Lost Hills, California – Tesla has commenced operations at the initial phase of Project Oasis, the world’s largest Supercharger site, in Lost Hills, California, marking a significant advancement in off-grid electric vehicle charging infrastructure. The site, which broke ground just eight months prior, now features 84 operational charging stalls, with plans to expand to 168 stalls later this year, making it the largest Supercharger facility globally.
What distinguishes Project Oasis is its complete energy independence. The operational phase is currently powered entirely by an 11-megawatt (MW) solar array and supported by 10 Megapack battery storage units. This configuration allows the station to operate 100% off-grid, drawing no power from the local utility grid. This rapid deployment and self-sufficiency underscore a new paradigm for EV charging, demonstrating Tesla’s integrated approach to energy generation, storage, and consumption.
Industry experts note that self-sufficient charging stations offer unparalleled resilience, providing a reliable power source for electric vehicles even during widespread grid outages or periods of peak demand. This capability not only enhances the robustness of EV infrastructure but also alleviates potential strain on existing electrical grids, particularly in regions experiencing rapid electrification. The ability for a site of this scale to operate autonomously represents a critical proof of concept for future energy systems.
According to the Tesla Charging team, the station’s design is a direct response to the increasing demand for sustainable and reliable charging solutions. By capturing solar energy, storing it on-site, and delivering it directly to vehicles, Project Oasis exemplifies a closed-loop energy ecosystem. This model minimizes reliance on fossil fuels and traditional grid infrastructure, aligning with broader clean energy transition goals.
The completion of the remaining stalls and an on-site lounge later this year will further solidify Project Oasis’s status as a benchmark for large-scale EV charging. This project’s swift execution, from groundbreaking to initial operation within eight months, highlights advanced construction methodologies and efficient project management within the renewable energy sector. The implications extend beyond EV charging, offering insights into distributed energy solutions and grid independence for various industrial applications. This initiative is anticipated to influence the development of similar resilient and sustainable charging hubs worldwide.
