Tesla Oasis Supercharger: 5 Numbers That Tell the Full Story

Tesla's Oasis Supercharger in Lost Hills, California just posted its Labor Day numbers — and they're worth paying attention to. Over four days of peak holiday travel on the I-5 corridor between Los Angeles and San Francisco, the station handled thousands of charging sessions without a single driver waiting in line. The data, shared directly by @TeslaCharging, puts some concrete figures behind what this station was designed to do.

1. 6,038 Charging Sessions in Four Days

That's not a typo. Over the Labor Day weekend, Oasis processed 6,038 individual charging sessions across its 164 V4 stalls — an average of roughly 1,510 sessions per day. For context, the station is designed to serve up to 1,000 vehicles daily according to published specs, meaning peak holiday demand pushed well beyond that baseline. The I-5 corridor is one of the busiest EV travel routes in the country, and Oasis absorbed the surge without breaking a sweat.

2. 11.2 Sessions Per Stall on Monday — Zero Wait Times

The single most telling stat from the holiday weekend: on Labor Day Monday itself, the station averaged 11.2 charging sessions per stall with zero waiters recorded. That's the metric that actually matters to drivers. High throughput without queues is the difference between a station that handles volume and one that merely has a lot of stalls. The 164-stall count — including 12 pull-through stalls for vehicles towing trailers — gave the station enough headroom to absorb the Monday peak cleanly.

3. 7 MW of Solar Generated On-Site

Oasis is equipped with an 11 MW ground-mounted solar farm plus solar canopies, and over the Labor Day period it generated 7 MW of solar energy on-site. That's not supplemental power — that's a meaningful share of what the station consumed being produced directly from sunshine in the Central Valley. As @wholemars noted, this is what a self-sustaining charging station actually looks like in practice, not just in a press release.



4. 39 MWh of On-Site Battery Storage Behind It All

The solar generation figure makes more sense when you factor in what's backing it up. Oasis runs 39 MWh of battery energy storage through 10 Tesla Megapacks, according to verified station specs. That buffer is what allows the site to keep charging even when solar output dips — at night, under cloud cover, or during demand spikes that outpace real-time generation. It's the combination of solar plus storage that makes the 7 MW solar figure operationally meaningful rather than just a marketing number.

5. 325 kW Peak Per Stall, Up to 15.8 MW Total Site Capacity

Each V4 dispenser at Oasis delivers up to 325 kW, powered by V3 electronics cabinets. Across all 164 stalls, the station's total peak capacity reaches 15.8 MW — well above the 7 MW solar output, which is why the Megapack storage exists. A December 2025 stress test reportedly pushed 7.5 MW of simultaneous usage across the site. The Labor Day weekend, with its 6,038 sessions and zero-wait performance, suggests the station is operating comfortably within its design envelope even under genuine holiday pressure.

What Oasis demonstrates isn't just that Tesla can build a big Supercharger. It's that the combination of scale, solar, and storage can make a charging stop on a long road trip genuinely frictionless — no circling for a stall, no watching a progress bar while someone else waits behind you. Whether that model gets replicated at other high-traffic I-5 and I-15 stops will be worth watching as holiday travel data from more stations comes in.
