Tesla‘s Supercharger network delivered a record 2.0 terawatt-hours of energy in the second quarter, up 30% from a year earlier, according to figures the company posted on X.
The disclosure landed a day before Tesla is due to report its second-quarter vehicle deliveries, a figure Wall Street expects to show little growth.
That contrast is the story.
Tesla‘s charging arm is posting record throughput at the same moment its core car-sales number is forecast to come in close to flat.
Charging sessions reached 60 million over the quarter, a 32% rise from the same period in 2025, according to the same figures.
The network itself grew about 17% year-over-year, with roughly 2,700 new Supercharger stalls opened during the quarter.
Energy delivered and session volume are climbing at close to twice the pace of the stall count, a gap that points to rising use of each connector rather than growth driven by hardware alone.
Utilization Rises as Waits Fall
The most striking claim in the figures concerns how hard the network is working.
Utilization, measured as charging sessions per stall per day, sits at an all-time high heading into the second half of 2026, on the company’s own chart.
At the same time, the share of sessions in which a driver had to wait for an open stall is near a record low, under roughly 1%.
Running a network harder while congestion falls is difficult to achieve, and the combination is the operational core of what Tesla is presenting.
The improvement is notable because opening the network to other brands had raised the prospect of longer queues.
When Tesla first opened its Superchargers to General Motors drivers, analysts and owners flagged the risk that wait times would lengthen as demand widened beyond the Tesla fleet.
The latest figures suggest capacity additions and faster hardware have so far absorbed that demand.
A Network Opening to Rivals
Much of the added volume reflects the network’s shift from a closed system into shared infrastructure.
Rivian, General Motors and Lucid drivers now reach the network through the North American Charging Standard, joining Ford, Mercedes-Benz and others that have adopted the connector.
Startups have followed, with Slate joining the roster of brands granted Supercharger access late last year.
That broadening base helps explain how session volume can outrun stall growth, since each connector now serves a far larger pool of vehicles.
Tesla operates more than 75,000 Superchargers worldwide across roughly 7,900 stations, and has been phasing out its V3 hardware in favor of the faster V4 cabinet built at its New York plant.
The company has also begun selling white-labeled Superchargers to third parties through its Supercharger for Business program, extending the network beyond sites it owns directly.
A 2025 J.D. Power study found Superchargers remained the most trusted fast-charging option among US electric-vehicle owners, even as satisfaction with public charging fell across the industry.
Estimates and Trip Planning
Alongside the throughput figures, Tesla said the quarter’s charging displaced about 934 million liters of gasoline and avoided roughly 3.8 billion kilograms of carbon-dioxide equivalent.
Those are modeled estimates rather than metered outputs, and the assumptions behind them were not disclosed.
The company also reported 5,000 site maps live and about 58,000 stalls mapped, references to the in-app trip-planning feature that shows drivers stall-level detail before they arrive.
The mapping push fits the wider theme, since reducing uncertainty about stall availability is one way to keep utilization high without adding congestion.
On Pace for a Record Year
The quarterly figure keeps the network on track for its strongest year yet.
Energy delivered in the first half of 2026 already sits near 3.9 terawatt-hours on the company’s annual chart, more than half of the roughly 6.8 terawatt-hours delivered across all of 2025.
Charging has grown into one of the clearest upward lines in Tesla‘s business, expanding steadily as vehicle volume has plateaued.
Tesla is scheduled to report second-quarter deliveries on Thursday, and the consensus compiled by its own investor-relations team from 22 firms stands at 406,024 vehicles, with a median of 408,609.
