Tesla Semi Charges at FM Harbor as Forum Marks Two-Charger MCS Launch

Forum Mobility marked the launch of two v4 Megawatt Charging Standard chargers at its FM Harbor depot in the Port of Long Beach with a customer’s production-model Tesla Semi charging at the site. The company’s November 6 announcement dates the ribbon-cutting to November 5.

This was not the opening of the depot itself, and the announcement does not establish November 5 as the chargers’ first day with power. Forum had already reported adding two Tesla MCS Megachargers on September 17. The new account adds the ceremony and inaugural production-truck charging sessions to that earlier hardware announcement.

Installation and launch are different milestones

Forum’s September release said FM Harbor had been operational since December 2024. It described the existing facility as having 44 CCS charging ports and 9 MW of overall capacity. Those are site-level figures from that announcement, not a specification for each new MCS charger or a measured charging rate for the truck at the November event.

A fleet plan is not a delivery total

IMC Logistics supplies a separate piece of fleet context. Its own newsroom announcement describes a plan to deploy 50 Tesla Semi battery-electric trucks in California for short-haul port operations and longer inland routes. The page carries a September 24 publication date and a November 4 update date.

That deployment plan should not be read as confirmation that all the trucks have arrived. Nor does a customer charging session establish Tesla’s broader production rate. The useful distinction is between a fleet’s stated procurement plan and a truck actually using charging infrastructure.

Charging capability versus measured performance

Forum says the MCS equipment is compatible with the production Tesla Semi and advertises recovery of up to 60% of range in 30 minutes. Its November release does not provide a session log, starting battery level, energy delivered or observed peak power. The advertised charging claim is therefore not a measured result from the ribbon-cutting.

For a dispatcher, that difference matters. A charger specification can inform a route plan, but it cannot establish how long a particular loaded truck will need to stop. Useful operating evidence would connect the truck’s arrival charge, energy added and departure time with the actual freight assignment.

What carriers can verify next

Forum’s current network map lists FM Harbor as operational and accepting reservations. It separately labels the Ontario, Adeline, Coliseum and Santa Fe locations as in development. An operating location and a planned network expansion should not be counted as the same thing.

The map also still describes FM Harbor’s established charging-port configuration without a separate MCS entry. For carriers considering the new equipment, that makes direct confirmation of booking terms and access more useful than assuming every listed port supports the same truck.

For Tesla, the development is a concrete customer-use milestone at a named freight depot. The next meaningful evidence would be repeat charging sessions and service availability, rather than another extrapolation from orders or charger specifications. Forum’s release documents the event; it does not yet supply those operating results.
