Tesla will operate public Megacharging equipment at four Forum Mobility truck depots in California, part of a broader buildout of the Megawatt Charging System (MCS) network that supports the Tesla Semi, according to a September 17, 2026 announcement from Forum Mobility.
Where the new chargers are going
Tesla will run public Megacharging at three sites — FM Francis in Ontario, and FM Adeline and FM Coliseum in Oakland — while a fourth depot, FM Santa Fe in Rancho Dominguez, has reserved fleet capacity for more than 330 Tesla Semi trucks without Tesla-operated public chargers. Together the four sites add roughly 30 megawatts of heavy-duty charging capacity, per Forum Mobility’s release, and the depots feature pull-through lanes so drivers can charge without detaching a trailer.
How it fits Tesla’s existing Semi charging
Forum Mobility already runs an MCS-equipped depot at the Port of Long Beach, FM Harbor, which has been operational since December 2024 with 44 CCS ports and 9 megawatts of capacity; two Tesla MCS Megachargers were recently added there. Combined with the new depots, Forum Mobility says it will have more than 40 megawatts of CCS and MCS charging online or under construction, serving 25 carrier customers. Forum Mobility’s MCS stalls are rated to add up to a 60% range boost in about 30 minutes, according to the company, though actual charge times will vary by truck and conditions.
The California buildout follows Tesla’s September 16 announcement that it plans to launch a public Megacharging network in Europe as well, starting with 21 sites across Germany, France, the Benelux countries, the UK, and Sweden, timed to the Semi’s planned launch there next year.
What it means for owners
None of this changes the passenger-vehicle Supercharger network directly — Megachargers use a different connector and are built for Class 8 trucks like the Tesla Semi. But the pace of depot announcements shows Tesla and its infrastructure partners are scaling MCS charging in parallel with Semi production, rather than waiting until after the truck ramps up. Owners who follow Tesla’s broader charging buildout can expect Megacharger and Supercharger expansion to keep proceeding on separate, if related, tracks over the next year.
