Tesla has filed pre-permits for its first public Semicharger station in San Antonio, Texas, marking a potential expansion of its charging network for the all-electric Semi truck, according to details reported by Supercharger sleuth Marco on X.
The proposed site at the Flying J Travel Center off Interstate 10 at North Foster Road will include eight dedicated charging stalls. Until now, Tesla’s Megacharger network has largely been confined to private facilities, serving the company’s operations and early partners, including distribution hubs such as PepsiCo’s Modesto facility and Tesla’s Gigafactories in Nevada and Austin.
The San Antonio project would represent the first installation of Tesla’s Semi charging hardware for public or third-party fleet use. By situating the station at a Flying J truck stop along Interstate 10—one of the busiest freight corridors in the United States—Tesla aims to integrate Semi charging into established long-haul routes, ensuring coverage in a key trucking hub.
The Tesla Semi, first delivered in late 2022, offers up to 500 miles of range per charge and is designed to reduce fuel and maintenance costs compared with diesel trucks. Wider access to public charging stations could encourage adoption among fleet operators that do not have resources to develop private charging depots.
Tesla has outlined plans to build 46 public Megacharger locations by early 2027 across California, Nevada, Arizona, New Mexico, Texas, and Georgia, with additional sites in Illinois. While the company has not shared an official construction timeline, the filing of pre-permits typically precedes city approvals and site work, indicating the San Antonio station could serve as a model for future public Semicharger installations.
