Tesla has been moving Supercharger pricing away from a fixed rate-by-time-of-day model toward pricing that moves with how busy a station actually is right now. If you charge on the road regularly, that shift changes how you should think about when and where you plug in.
Under the older system, Tesla set higher and lower per-kWh rates for specific hours of the day based on estimated busy times, shown on a chart in the app. The newer approach, which Tesla began piloting at 10 North American Supercharger sites in 2025 according to Not a Tesla App, prices a stall based on how many other cars are charging there at that moment, not the clock. A busy station costs more; a quiet one costs less. Tesla also added a “Find Lower Price Charging” feature that points you to a cheaper nearby station if the one you’re at is running a premium rate.
The rollout has grown well beyond that initial pilot. As of November 2025, live congestion-based pricing was active at more than 550 Supercharger stations across Florida, California, New Jersey, Illinois, and New York, per Notebookcheck. Tesla told the outlet that the average rate paid across participating stations hasn’t changed overall, but that fewer drivers are hitting true peak pricing under the new model. Coverage has likely expanded further since then, so check the price shown in your car before you plug in rather than assuming your local station still runs the old system.
A few practical takeaways. Prices lock in once you start a charging session, so what you see on the screen when you plug in is what you’ll pay for that session — it won’t rise mid-charge. If a nearby station shows a lower live price than the one you’re parked at, unplugging and plugging back in at that price (or driving the short distance to the cheaper site) is the only way to capture it; the rate doesn’t drop automatically at your existing stall. And because pricing tracks real-time demand rather than a fixed schedule, the old advice to charge late at night doesn’t guarantee a discount anymore — a quiet Supercharger at 2pm on a Tuesday can be cheaper than a crowded one at midnight on a holiday weekend.
Your best move is the same either way: check the live price and any nearby alternatives in the Tesla app or your car’s touchscreen before you start charging, especially on high-traffic travel days when congestion pricing is most likely to kick in.
