Tesla activates world’s largest Supercharger site

Just over a year ago, Max de Zegher, Director of Charging for North America, Europe, the Middle East, Africa, and Asia Pacific at Tesla, announced plans for a massive charging park located halfway between San Francisco and Los Angeles on Interstate 5. The site was intended to feature as many as 168 Superchargers.

Only eight months after breaking ground, in July of this year, the first 84 Superchargers became operational. Images released by Tesla at the time provided an early glimpse of the scale of the covered charging park. Now, Tesla has announced that the remaining Superchargers have also been activated. While the final count is slightly lower at 164 instead of the originally planned 168, this still makes the charging hub, dubbed ‘Tesla Oasis’ by the company, the largest Supercharger site in the world to date. Additionally, each Supercharger is reported to deliver charging power of up to 325 kW.

Marking the site’s activation, de Zegher shared on the platform X: “Our forecasts showed a severe charging infrastructure deficit along the San Francisco – Los Angeles corridor for the 2025 holidays and beyond, creating extreme urgency to bring more Superchargers online.” However, securing a grid connection in time would have been impossible. “With our own solar generation and Megapacks, we have control of our timeline, delivering the needed capacity in under 8 months from construction start,” de Zegher added.

The result: all 164 Superchargers draw their energy from an 11-megawatt photovoltaic system. Most of the solar panels are not installed on the roofs of the charging stations but are instead situated on open land behind the charging park. Excess energy is stored in ten Tesla Megapacks, which provide a combined capacity of 39 MWh and release power as needed.

De Zegher also noted that the charging park operates almost entirely autonomously: “We have a small utility connection but it will mainly be used for future expansions. For almost every day of the year, it’s 100% sunshine powering cars.” However, no specifics were provided about the capacity of the grid connection. Earlier reports in July suggested it was 1.5 MW, which would be sufficient to power just over four Superchargers at full capacity per station.
