Tesla plans to deploy a public charging network for its Tesla Semi truck, starting with 46 stations in 2027, according to a new presentation.

At a new presentation at the ACT Expo this week, Tesla’s head of the Semi program, Dan Priestley, revealed several new details about the long-awaited electric semi-truck.

During the presentation, Priesley claimed that Tesla Semi trucks have already cumulatively traveled 7.9 million miles (12.7 million km).

He didn’t disclose how many trucks contributed to this total mileage, but he did add that “more than 26 Tesla Semi trucks” have each traveled over 100,000 miles.”

These numbers have been updated from a previous presentation in September 2024, when Priestley said the Tesla Semi fleet had traveled 7.5 million miles and that a single truck had traveled 250,000 miles (400,000 km) over the last 1.5 years.

Tesla also confirmed that the truck is going to be equipped with a 25 kW Power Take Off (PTO) at the back to power external systems, like a refrigerated trailer, for example (via Jake Guerra on LinkedIn):

Priestley also revealed a few more details about Tesla’s planned expansion of its charging network for the Tesla Semi.

The company currently operates the Supercharger network. It is the most extensive EV fast-charging network in North America, but it is geared toward passenger electric vehicles and not practical for bigger commercial vehicles, like Tesla Semi.

Tesla has already deployed Megachargers, its charging station for electric semi trucks, at its own installations and those of a few customer-partners who have been testing the Tesla Semi, but now it plans to deploy public charging stations to enable long-haul trucking with the electric truck.

Priestley said that Tesla is now aiming to deploy 46 Megacharging stations as part of its public charging network by early 2027.

It is not clear whether the locations on the map accurately represent the plans, but it appears likely based on previously reported Megacharger information.

The presentation follows an update released by Tesla this week about the Tesla Semi factory in Nevada.

The automaker aims to start volume production of the truck in 2026.

Tesla Semi was first supposed to enter production in 2019, but it has been significantly delayed as Tesla tried to deliver on the promise of range and capacity.

It appears that the automaker may be able to deliver on those, but at a significantly higher price than previously announced, as we recently reported.
