Tesla opens its first Semi Megacharger station in the United States

Tesla has just taken an important step forward in deploying charging infrastructure for its Semi electric truck with the opening in Ontario, California, of its first public Megacharger station. Located at 4265 E Guasti Road, the facility is already operational for Semi fleet owners.

For now, the Megachargers available there deliver 750 kW, below the 1.2 MW that Tesla’s technology is capable of delivering, but it will probably only be a matter of time before they reach their full potential.

Until now, the company had two operating Megacharger stations, one at the Nevada Gigafactory and another in Carson, California, near the Port of Long Beach. However, both were reserved exclusively for Tesla’s internal use or, at best, for a small group of partners. The new Megacharger station in Ontario is open to all owners of a Tesla Semi, anticipating the start of large-scale series production of this electric truck.

More Megacharger stations on the way

Tesla recently updated its location map on its US website, adding more than 60 new Megacharger stations set to open soon in 15 US states. The rollout is concentrated along the main logistics corridors, from the West Coast to the East; Texas accounts for the largest number with a total of 19 planned facilities, while California follows closely with 17. All these new stations are listed as “coming soon“, with no specific opening dates.

After several years of delay since its unveiling in 2017, Tesla is finally preparing to begin large-scale commercialization of its Semi electric truck in 2026. Production will take place in a plant dedicated to this purpose next to the Nevada Gigafactory, whose construction was completed at the start of 2025 and where the installation of the assembly lines is currently being finalized. Once it is fully operational, the plant is estimated to have an annual production capacity of 50,000 units.

Finally, it should be noted that the commercialization of the Semi truck will not be limited to the North American market. Tesla has already confirmed its intention to sell it in Europe as well, although some time later, probably in 2027.
