EVwire brief: The Tesla Supercharger network delivered a record 2.0 TWh of energy in the second quarter of 2026, up 30% year-over-year, according to the official Tesla Charging account on X. The network also opened around 2,700 new stalls in the quarter, a 17% year-over-year increase in its footprint.
Quarterly charging sessions climbed 32% year-over-year to 60 million. The network also saved 934 million liters of gasoline and avoided 3.8 billion kg of CO2e over the three months.
Tesla highlighted a newer in-app feature on the scorecard as well: 5,000 Supercharger site maps are now live, covering more than 58,000 mapped stalls.
Here's Tesla's Q2 2026 Supercharger scorecard:

Even as the network expands, it is getting more out of each stall. Tesla's utilization curve shows average sessions per stall per day rising from around 3 to 4 in 2019 to roughly 8 by 2026. Over the same stretch, the share of drivers who have to wait has fallen the other way, from peaks near 2 to 2.5% down to about 0.5 to 1% today.
Here's how that trend looks:

Step back further and the network's energy output has grown exponentially. Tesla delivered close to 7 TWh across all of 2025, and 2026 is already well on its way, with roughly 3.8 TWh banked through the first half, Q1's 1.8 TWh plus Q2's 2.0 TWh.

Context:
The Q2 numbers build on a strong start to the year. In Q1 2026, the network delivered 1.8 TWh (up 22% year-over-year), opened about 2,500 stalls, and logged 53 million charging sessions, while saving 823 million liters of gasoline and avoiding 3.4 billion kg of CO2. The full Q1 2026 scorecard is here.
Set side by side, Q2 extends the climb on nearly every line: energy up from 1.8 to 2.0 TWh, sessions from 53 to 60 million, and both growing faster year-over-year than they did in Q1, energy at 30% versus 22% and sessions at 32% versus 26%. The site-map count is new to the scorecard this quarter.
