Heavy-duty electric trucks hauling freight out of the Port of Long Beach are now plugging into Tesla's Megawatt Charging System, as Forum Mobility rolls out new charging infrastructure meant to keep zero-emission semis moving across California. The company has begun installing Tesla's Megacharger units at FM Harbor, its flagship depot near the port, with more depots planned in Rancho Dominguez and Oakland over the next year.
Forum Mobility has begun installing Tesla's Megacharger units with MCS at FM Harbor, according to evwire.com. The depot has been operational since December 2024, and at the time it opened it offered nine megawatts of power and 44 fast-charging dispensers, per truckingdive.com. That outlet also reported the site has capacity for hundreds of trucks per day near a port that handles 7,000 trucks daily.
A Second Southern California Depot Takes Shape
Forum Mobility's next major build is FM Santa Fe in Rancho Dominguez, which will feature 14 MCS pull-through charging lanes when it opens in the first quarter of 2027, evwire.com reported. Electrek, describing the same project, put the planned charger count at 14 megawatt-class units with capacity to support more than 200 zero-emission trucks' daily charging needs, according to electrek.co.
The demand behind that build-out is already lining up. Forum Mobility has 100 Tesla Semis on order across four operators serving Southern California port freight routes, evwire.com reported. Electrek's account names two of those fleets specifically: Big F Transport, which committed to 40 units, and NICA Container Freight Line, which ordered 20, with both expected to begin operations from the Rancho Dominguez depot in early 2027. Big F Transport already operates nine Daimler eCascadia electric trucks from a Port of Long Beach facility, per the same account.
How Forum Mobility's Business Model Works
Forum Mobility's approach spans the whole supply chain around electrification. The company owns and operates the trucks, builds and runs the charging depots, and leases the vehicles to drayage companies, evwire.com reported, a structure meant to lower the barrier for smaller trucking operators to go electric. Backing that expansion is a $400 million joint venture with CBRE Investment Management to build out the charging-depot network, according to mgrid.org.
The company is also planning four additional shared depots during 2026 and into 2027, per electrek.co's reporting, though specific locations beyond Rancho Dominguez and Oakland were not detailed in that account.
Oakland Gets Two Depots of Its Own
Up north, Forum Mobility is building two electric-truck charging depots in Oakland — FM Adeline and FM Coliseum — according to Forum Mobility. FM Adeline, located at 1407 Middle Harbor Rd in the Port of Oakland, will feature four ultra-fast MCS pull-through lanes and four CCS bobtail charging stalls, the company said. FM Coliseum, at 5051 Coliseum Way, will have 16 pull-through lanes with ultra-fast MCS chargers.
Both Bay Area sites are planned to run 24 hours a day, seven days a week to serve carrier needs, the company said. Forum Mobility is also developing what it calls the Market Acceleration Program with the Port of Oakland, aimed at reducing the costs of electric trucks for carriers serving the port.
Part of a Bigger Tesla Charging Push
The Long Beach and Oakland projects fit into a broader Tesla Megacharger rollout. Tesla updated its Find Us map with 64 new Megacharger locations across 15 states to support the Semi, electrek.co reported, bringing the total shown to 66 locations, including two already operational. California accounted for 17 planned sites — the second-highest total among states listed, behind Texas's 19 — though electrek.co noted all 64 planned sites were listed only as coming soon, without specific opening timelines as of that February report.
Interest in the Tesla Semi itself appears to be building alongside the charging network. The truck accounted for 965 of 1,067 applications to California's Clean Truck & Bus Voucher program between January 2025 and February 2026, according to electrek.co. Still, the scale of the shift remains small: electric heavy-duty trucks make up fewer than 300 of the roughly 1.8 million trucks in California subject to the state's clean-fleets and clean-trucks rules, per Canary Media.
Rivals Are Racing to Build Too
Forum Mobility isn't alone in chasing California's electric-truck charging gap. WattEV announced plans to build three more electric-truck charging depots in the state using $75.6 million in federal grants, Canary Media reported, with a combined total of 258 charging points. Two of those sites, in Gustine and Taft, will include 17 megawatt chargers alongside 175 standard DC fast chargers. Separately, TeraWatt Infrastructure has $1 billion in financial backing to develop charging hubs for light- and heavy-duty electric vehicles nationwide, the outlet noted.
WattEV has also ordered 370 Tesla Semi trucks for California operations, with deliveries of the first 50 expected as early as 2026 and the full fleet operational by the end of 2027, according to cbinsights.com. Tesla has separately struck a deal with Pilot Travel Centers to begin constructing Semi chargers at select locations in California, Georgia, Nevada, New Mexico and Texas starting in the first half of 2026, per electrek.co.
On LinkedIn, Forum Mobility said its customers have made reservations for hundreds of Tesla Semis and that its depots are planned to feature Tesla-compatible Megawatt Charging System charging — a sign the company sees the infrastructure build-out and truck orders moving in tandem as California pushes toward zero-emission freight, as first detailed by the Charlotte Observer.
