Tesla’s Semi Megacharger network is getting another major boost, with Forum Mobility preparing to break ground on four new heavy-duty electric truck charging depots in California.
According to Forum Mobility, the four facilities will add approximately 30 MW of charging capacity across Northern and Southern California, with both traditional CCS chargers and the newer Megawatt Charging System (MCS).
Tesla will have a direct role at three of the new locations, operating public Megacharging at Forum Mobility locations in Ontario and Oakland. All three will be public and open to commercial carriers, rather than being reserved exclusively for Tesla’s own Semi fleets.
The fourth site will be in Santa Fe, New Mexico, which already has contracted fleet offtake covering more than 330 Tesla Semis. Despite that commitment, Forum says public charging access will remain available to other commercial operators.
The new depots will feature pull-through MCS lanes, allowing trucks to charge without disconnecting their trailers. According to Forum, MCS hardware can add up to approximately 60% of a truck’s range in about 30 minutes.
Forum is also expanding its existing Megacharger infrastructure at their depot at the Port of Long Beach. That facility has been operational since December 2024 with 44 CCS ports and 9 MW of capacity, and has now received two Tesla Megachargers.
While the network is growing in the U.S., it may soon be coming to Canada. As Drive Tesla previously reported, Tesla has been planning a Canadian Semi Megacharger rollout along Ontario’s Highway 401 corridor, laying the groundwork for the Semi’s eventual arrival north of the border.
Tesla has also been working to speed up deployments with pre-assembled Megacharger stations, which arrive largely assembled and can significantly reduce on-site construction work.
