Tesla is preparing to build its largest Supercharger station yet, with over 400 V4 stalls, at the Eddie World site in Yermo, California. The project involves six phases, starting with 72 stalls in 2026, to address high demand on the I-15 corridor between Los Angeles and Las Vegas.
Tesla has submitted plans for a significant expansion of its Supercharger network at the Eddie World location in Yermo, California, aiming to create a station with more than 400 V4 charging stalls. This development, first highlighted by Tesla enthusiast MarcoRP on March 6, 2026, will unfold across six phases adjacent to the existing site, which currently features 22 older V2 and V3 stalls limited to 150 kW charging speeds.
Phase 1 construction is set to begin later in 2026, adding 72 V4 stalls, with subsequent stages progressively increasing capacity to exceed 400 stalls. Site plans include expansive parking arrays along Calico Boulevard for Phases 1 through 5, while Phase 6 details remain undetermined. The location, midway along Interstate 15 between Los Angeles and Las Vegas, serves heavy electric vehicle traffic in an area already equipped with over 200 high-power stalls, including 40 at 250 kW and 120 at 325 kW, plus 96 more nearby in Baker. Despite this infrastructure, bottlenecks continue during peak travel periods.
This project surpasses Tesla's current largest Supercharger, the 168-stall facility in Lost Hills, California, powered by solar and Megapack systems. The new station incorporates EV-friendly designs, such as pull-through bays for Cybertrucks and trailers, and integrates retail amenities including a 10,100-square-foot Cracker Barrel, a 4,300-square-foot McDonald's, a 3,800-square-foot convenience store, additional restaurants, drive-thrus, outdoor dining, and lease spaces.
As noted by Sawyer Merritt on March 7, 2026, the initiative marks what will be the world's largest Supercharger, with Phase 1 of the six-phase build starting in 2026. The expansion underscores Tesla's efforts to enhance charging capacity on high-demand routes.
