What changed
Forum Mobility said it held a November 5 ribbon-cutting for two new v4 Megawatt Charging Standard chargers at FM Harbor, its existing Port of Long Beach electric-truck charging depot. The company said the event included the first customer charge sessions for a production-model Tesla Semi at the site.
Forum Mobility's network page lists FM Harbor as operational and accepting reservations. It identifies the depot as a 9-megawatt site with 44 existing 360-kilowatt charging ports; the November announcement adds two MCS chargers to that operating location.
What it means for drivers and fleets
The new equipment gives participating fleets a higher-power charging option at an already operating port-area depot. Forum Mobility says the chargers can restore up to 60% of a compatible truck's range in 30 minutes, but that is a company performance claim rather than a guaranteed result for every truck, battery condition or duty cycle.
This does not create a CDL rule, vehicle mandate or dispatch requirement. Drivers and fleet managers still need confirmed reservations, access terms, pricing and vehicle compatibility before planning a charging stop.
What remains planned or uncertain
Forum Mobility says the two Long Beach chargers are the first portion of 30 megawatts of MCS capacity it plans to bring online in coming months. The company also says four additional California depots are under construction in Rancho Dominguez, Ontario and two Oakland locations; those separate sites are not being reported as open.
Forum Mobility also reports 25 carriers with contracted capacity, reservations associated with more than 330 Tesla Semis and more than 40 megawatts of CCS and MCS charging online or under construction. Those customer, reservation, cost and future-capacity figures are company claims and were not independently audited for this update.
