The News: Tesla has filed plans to expand its Yermo, California Supercharger from 18 stalls to a total of 306 stalls — potentially the largest Supercharger station in the world.
Why It Matters: The I-15 corridor between Los Angeles and Las Vegas is one of the most heavily traveled EV routes in the country. A 306-stall station at Yermo would be a game-changer for road-trippers and reduce wait times dramatically.

Tesla Eyes Yermo for Record-Breaking Supercharger Expansion
Tesla has revealed plans to massively expand its Supercharger station in Yermo, California — a critical stop on the I-15 corridor between Los Angeles and Las Vegas. According to newly surfaced plans, the site would grow from just 18 stalls today to a staggering 306 total stalls, which would make it the largest Supercharger station on the planet.
The expansion breakdown, as reported by The Tesla Newswire, includes 288 additional Supercharger stalls on top of the existing 18, with 12 of those designated as accessible charging spots and 4 configured as pull-through stalls — ideal for owners towing trailers or driving larger vehicles like the Cybertruck.
📊 What Changed
| Metric | Before | After (Planned) |
|---|---|---|
| Total Stalls | 18 | 306 |
| Accessible Stalls | Unknown | 12 |
| Pull-Through Stalls | Unknown | 4 |
| World Ranking | Regional stop | Potentially #1 globally |
Context: Where Does This Rank?
To appreciate the scale of what Tesla is planning, it helps to know where the bar currently sits. Tesla's "Oasis" Supercharger in Lost Hills, California is currently the world's largest operational Supercharger station, with 164 stalls. It opened in late November 2025 and is powered by 11 megawatts of solar generation plus 10 Megapack battery units providing 39 megawatt-hours of storage — making it largely off-grid.
Separately, Tesla has also filed plans to expand its Firebaugh, California Supercharger to a combined 320 charging points (304 passenger EV stalls plus 16 dedicated Tesla Semi Megachargers), according to reports from January 2026. The Yermo plans, if confirmed and completed first, would leapfrog both sites.
📊 Large Supercharger Stations at a Glance
| Location | Stalls | Status |
|---|---|---|
| Lost Hills, CA ("Oasis") | 164 | Open |
| Firebaugh, CA | 320 (total w/ Semi) | Planned |
| Yermo, CA | 306 | Planned |

Important note: These are filed plans, not a completed build. No construction timeline or opening date has been officially announced for the Yermo expansion. Treat this as early-stage infrastructure planning — significant, but subject to change.
🚦 Owner's Action Plan
Verdict: Informational
No immediate action required — this is a future infrastructure project. But here's how to stay ahead of it.
- If you drive the LA–Las Vegas corridor regularly: Bookmark the Yermo Supercharger location in your Tesla app. When this expansion opens, it will dramatically change how you plan charging stops on this route.
- If you tow with a Cybertruck or Model X: The 4 pull-through stalls are specifically designed for you. Watch this location — it could become your go-to stop on I-15.
- If you have accessibility needs: 12 dedicated accessible stalls is a meaningful number. This site is being designed with inclusive charging in mind.
- Monitor the Tesla app and PlugShare for construction updates. Large Supercharger builds typically show up in the app as "coming soon" months before opening.
- Don't reroute your trips yet. No completion date is confirmed. Continue using the existing Yermo and Lost Hills stations for now.
📰 Deep Dive
Yermo's location on I-15 makes it one of the most strategically important Supercharger sites in the United States. The stretch between the greater Los Angeles area and Las Vegas sees enormous EV traffic — especially on holiday weekends when queues at existing stations can stretch to 30+ minutes. A 306-stall facility at this location would effectively eliminate charging anxiety on this corridor for the foreseeable future.
The inclusion of pull-through stalls signals that Tesla is designing this site with Cybertruck towing use cases in mind. The current Lost Hills "Oasis" station also features 12 pull-through stalls, and the positive reception from the towing community appears to be influencing future site designs. For owners who regularly haul trailers or boats to Las Vegas or beyond, this is a meaningful quality-of-life upgrade.
What's notable about this announcement is that Tesla is simultaneously pursuing multiple mega-station projects in California. With Firebaugh already in the pipeline and Yermo now surfacing, the company appears to be systematically targeting its highest-traffic corridors for hub-scale charging infrastructure. This is a different strategic posture than simply adding stalls incrementally — these are destination-grade facilities designed to handle peak demand without compromise. For more on how Tesla's charging network is evolving, we'll continue tracking both projects as they develop.
