EVwire brief: Tesla's Superchargers pumped out a record 2.4 TWh of energy in Q3 2026, 29% more than a year earlier, as the company opened around 2,700 new stalls and grew the network 15% year-over-year.
Charging sessions also rose 29% year-over-year to 69 million for the quarter. Tesla Charging said the network saved 1.1 billion liters (about 291 million gallons) of gasoline and avoided 4.4 billion kg (about 9.7 billion lb) of CO2e over the three months.
This quarter's scorecard also carries a new robotaxi line, listing 7.0 GWh of "Robotaxi Energy" next to a "100% Autonomy Unlocked" figure. Tesla did not explain what the second number refers to.

The network is also busier than ever on a per-stall basis. Tesla's utilization chart shows average sessions per stall per day climbing past 10 at its 2026 peak, the highest point on a chart that goes back to 2019. The share of drivers who have to wait for a stall has moved the other way, dipping to around 0.5%, the lowest level on the chart.
Here's how that trend looks:

Tesla's energy chart puts the year in perspective. Adding Q1's 1.8 TWh, Q2's 2.0 TWh and Q3's 2.4 TWh, the network has delivered about 6.2 TWh so far in 2026, within roughly 0.6 TWh of 2025's full-year total of about 6.8 TWh with a quarter still to go.
