Tesla Megacharger Sites Expand at Three California Depots

Tesla Expands Public Megacharging Across Three California Depots

Tesla will operate public Megacharger sites at three of four new Forum Mobility electric truck depots in California, expanding access to heavy-duty charging infrastructure. Forum Mobility has reservations for more than 330 Tesla Semis and plans to add another 30 MW of charging capacity across its depot network. The public Megacharging locations will be at FM Francis in Ontario, FM Adeline in Oakland, and FM Coliseum in Oakland. The fourth site, FM Santa Fe in Rancho Dominguez, is reserved for Forum's future fleet of Tesla Semis rather than public charging operations.

Forum Mobility Depots Combine MCS and CCS Charging

All four Forum Mobility depots use pull-through charging lanes designed so electric truck drivers can connect to charging equipment without disconnecting their trailers. The facilities combine the new Megawatt Charging System, or MCS, with conventional Combined Charging System, or CCS, ports. This configuration gives operators access to different charging standards within the same depot environment while supporting the operational requirements of heavy-duty trucking. The approach is particularly relevant for fleets that need to minimize charging-related handling and keep tractor-trailer operations moving efficiently during depot visits.

Existing Long Beach Depot Demonstrates Tesla MCS Deployment

Forum Mobility has already deployed two Tesla MCS Megachargers at its FM Harbor depot at the Port of Long Beach. The charging equipment has been operating there since December 2024 alongside 44 CCS ports and a total site capacity of 9 MW. That installation provides an operating example of the charging configuration Forum is extending to its newer facilities. The expansion across Ontario, Oakland, and Rancho Dominguez therefore builds on an existing heavy-duty charging deployment rather than representing the company's first use of Tesla's MCS equipment.

Tesla Megacharger Pricing Supports Third-Party Charging

Tesla sells its Megacharger hardware to companies for USD 188,000 and retains USD 0.08 per kWh from charging conducted at third-party sites. The stated energy charge is 20% below Tesla's Supercharger for Business rate. This commercial model allows Tesla to participate in charging operations beyond facilities dedicated exclusively to its own vehicles. Forum Mobility's decision to deploy the equipment at multiple depots consequently creates a public charging network in which Tesla hardware can serve a broader heavy-duty trucking market.

MCS 3.2 Opens Charging to Multiple Truck Brands

The Megacharger hardware operates on the open MCS 3.2 standard, which expands compatibility beyond Tesla vehicles. Under this standard, the charging equipment can also charge electric trucks from Daimler, Volvo, and Scania. That interoperability is significant for commercial fleets because operators may use vehicles from multiple manufacturers while relying on shared charging infrastructure. Forum Mobility's combination of MCS and CCS ports therefore supports a broader range of electric truck configurations and reduces the need for a depot to depend on a single vehicle manufacturer's charging ecosystem.

Industry Impact & Outlook

The expansion gives heavy-duty electric trucking operators additional public charging capacity while demonstrating how MCS infrastructure can be deployed across multi-brand commercial vehicle networks. Forum Mobility's planned 30 MW addition also indicates that depot-scale charging is becoming an important part of the infrastructure required for larger electric truck fleets. The use of open MCS 3.2 hardware could allow the same charging sites to serve vehicles from several manufacturers, while the dedicated Tesla Semi depot preserves capacity for Forum's own future fleet. Further deployment will depend on fleet demand, depot utilization, and the continued expansion of compatible electric trucks.

Frequently Asked Questions

Where will Tesla operate public Megacharger sites for Forum Mobility?
Tesla will operate public Megacharger sites at three Forum Mobility depots in California, including FM Francis in Ontario and FM Adeline and FM Coliseum in Oakland. The fourth depot, FM Santa Fe in Rancho Dominguez, is intended for Forum Mobility's future Tesla Semi fleet rather than public charging. The four facilities use pull-through lanes and combine MCS equipment with CCS ports to support heavy-duty electric truck charging without requiring drivers to disconnect their trailers.
