Tesla Opens Electric Truck Megacharger Hub for Semi Customers

Tesla has inaugurated its first publicly accessible Megacharger station for Semi customers in Ontario, California. While two other Megacharger locations in the US exist, they primarily serve Tesla’s internal fleet. The Ontario hub marks a key step in expanding Tesla’s electric truck infrastructure for commercial operators.

Ontario Megacharger Now Operational

Located at 4265 E Guasti Road, the new Megacharger is open to Tesla Semi owners and offers 750 kW of charging power, with the technology capable of delivering up to 1.2 MW. The hub joins Tesla’s existing internal sites at the Gigafactory Nevada and Carson, California, near the Port of Long Beach.

Tesla recently updated its “Find Us” map to show over 60 new Megacharger locations across 15 states, providing the most comprehensive overview of the charging network for its electric truck program. Including the three existing megawatt-scale hubs, the network will total 65 charging locations along major freight corridors from the West to East Coast. Texas leads with 19 planned stations, followed closely by California with 17.

Expansion Plans and Pilot Travel Partnership

Construction is planned at selected Pilot Travel Center locations in California, Georgia, Nevada, New Mexico, and Texas, beginning in the first half of 2026. Each hub will feature 4–8 chargers using Tesla’s V4 technology capable of up to 1.2 MW, designed to restore most of the Semi’s 800 km range in about 30 minutes.

Initially, the chargers are reserved exclusively for Tesla Semi customers, though the network could open to third-party trucks in the future. Pilot operates around 900 sites across 44 US states and five Canadian provinces, with locations chosen based on heavy-duty charging demand.

Tesla Semi Production and Market Launch

The infrastructure build-out signals that the Tesla Semi is approaching its market launch in 2026, after years of delays. Production will take place next to Gigafactory Nevada, with an annual capacity of 50,000 units. The Semi, first unveiled in 2017, was initially promised for 2019 but faced repeated delays.

The Semi is not only intended for the US market; Europe is also in line for deliveries. The truck attracted attention at the IAA in Hanover, showcasing significant demand and anticipation ahead of its official launch.

The launch of the Ontario Megacharger represents a major milestone for Tesla’s electric truck ambitions. With an expanding network of high-power charging stations, Tesla is preparing the ground for its Semi trucks to operate efficiently across North America, supporting sustainable freight operations and faster adoption of electric commercial vehicles.
