Tesla plans to operate public Megacharger charging sites at three new electric truck depots managed by Forum Mobility in California, although Tesla will not own the sites. The arrangement indicates that expansion of Tesla Semi’s charging network relies on partnerships with depot operators, alongside sites that Tesla builds or owns directly.
Where will the charging sites operate?
According to Forum Mobility, Tesla will operate charging at the FM Francis depot in Ontario, and at FM Adeline and FM Coliseum in Oakland. The fourth depot, FM Santa Fe in Rancho Dominguez, has its contracted capacity reserved for fleets comprising more than 330 Tesla Semi trucks, while also remaining available to the broader container-hauling industry.
All four depots use pull-through lanes that allow drivers to charge the truck without disconnecting the trailer. They also combine Megawatt Charging System (MCS) ports with traditional CCS ports. Forum says MCS chargers can add up to 60% of a truck’s range in about 30 minutes.
FM Francis is particularly significant because it is located in Ontario itself, where Tesla opened its first public Megacharger station in March. Forum also added two Tesla chargers supporting MCS to the FM Harbor depot at the Port of Long Beach, a site that has been operating since December 2024 and includes 44 CCS ports and 9 megawatts of capacity.
An operating model different from owning the sites
Under this model, Tesla manufactures the Semi truck and the Megacharger, but operates the charging equipment at sites owned by Forum Mobility. This allows the company to generate revenue from operating the chargers without managing the properties that host them.
Tesla sells the Megacharger hardware for $188,000 and charges $0.08 per kilowatt-hour at charging sites operated by third parties, according to the information provided in the article. That rate is 20% lower than the Supercharger for Business price. The equipment also operates under the open MCS 3.2 standard, allowing electric trucks from Daimler, Volvo, and Scania—not only the Tesla Semi—to charge.
Why does this expansion matter?
Forum Mobility says its additional heavy-duty charging capacity will reach 30 megawatts, while its portfolio includes 25 transportation-company customers and more than 40 megawatts of operating or under-construction capacity. Its depots are concentrated near Oakland and Long Beach, where container-hauling trucks operate on short, predictable routes—conditions suited to electric vehicles.
The deal demonstrates in practice how charging infrastructure for heavy-duty vehicles can expand through depots dedicated to fleets, rather than relying exclusively on standalone public stations. Tesla’s map currently shows 66 planned Megacharger sites, while the Forum partnership points to one of the avenues that could fill part of that plan.
However, the announcement alone does not establish when the three sites will begin operating or the details of their availability and final pricing for drivers. Part of FM Santa Fe’s capacity is also tied to specific fleet contracts, even as the site has been announced as available to the broader container-hauling community. Forum plans subsequent sites in areas including the Inland Empire, Central Valley, Las Vegas, Phoenix, Houston, Dallas, Seattle/Tacoma, and Chicago, and the California sites were partially funded by government and regional grants.
