Tesla Semi Megachargers Go Live at the Port of Long Beach

Tesla Semi drivers now have two new Megachargers available at the Port of Long Beach, where Forum Mobility marked the opening with a charging session featuring a customer's production-model electric truck. The V4 Megawatt Charging Standard (MCS) units are installed at FM Harbor, Forum's flagship electric truck charging depot, where the chargers can restore up to 60 percent of a truck's range in 30 minutes.

Tesla Charging highlighted the opening on X, pointing Semi buyers toward its business charging program and describing private charging sites as a way to improve ownership costs and the operating experience.

What the Long Beach site delivers

• Two V4 Megachargers now operational at FM Harbor, Port of Long Beach
• Recovery rate: up to 60% of truck range in 30 minutes
• Forum's cost claim: electricity for truck charging at a cost 40% below diesel (fuelling costs only, not total ownership)

Forum's wider buildout

For Forum, the Long Beach installation is part of a much larger expansion aimed at trucking companies shifting to electrification. The company currently has another 30 MW of charging infrastructure under construction at four California depots — Rancho Dominguez, Ontario, and two in Oakland — with further locations in development across California's Inland Empire and Central Valley, plus Las Vegas, Phoenix, Houston, Dallas, Seattle/Tacoma, and Chicago.

Forum says 25 carriers have contracted charging capacity, and its customers hold reservations for more than 330 Tesla Semis.

The Canadian angle

For Canadian fleets, the Long Beach opening is a milestone in the broader Semi charging story that already has a domestic footprint. Tesla has introduced Semi Charging for Business in Canada, which offers both high-power Megachargers and slower Basechargers — giving operators a choice between quicker stops and longer periods parked at their own depots. Earlier this year, Tesla also deployed its first pre-assembled Megachargers in Canada, factory-built units that cut on-site construction and electrical trenching.

The Long Beach depot is a useful template for what Canadian fleet operators can expect as the Semi charging network matures: dedicated private sites, megawatt-class hardware, and a total-cost-of-ownership pitch built around the gap between electricity and diesel.
