Tesla lands the largest-ever Semi electric truck order: 370 units worth $100 million

US electric freight operator WattEV announced it will place an order with Tesla for 370 Semi electric trucks, with a total value of as much as $100 million. This is not only Tesla Semi’s largest single order to date, but also the largest truck procurement project in California to date. The deal will accelerate the progress of zero-carbon freight transport along the North California and Central California port corridors, and it marks an important milestone for the electrification of heavy freight in the United States.

WattEV places an order for 370 Tesla Semi electric trucks at $100 million

US electric freight operator WattEV recently announced that it has signed a procurement contract with Tesla (Tesla) worth approximately $100 million to order 370 Tesla Semi electric trucks. This is not only the largest single electric Class 8 heavy truck procurement in California’s history, but also the biggest order Tesla Semi has received since its commercialization, becoming an important milestone in accelerating the adoption of zero-emission long-haul freight.

WattEV CEO Salim Youssefzadeh said publicly at the annual ACT Expo industry event that during the public tender evaluation process, Tesla Semi won in all three core categories—cost, performance, and supply capability—thereby becoming the final choice. He also emphasized that WattEV adopts a “vertical integration” business model that combines vehicle deployment, megawatt-class charging infrastructure buildout, and end-to-end leasing services, offering freight operators a one-stop solution with zero capital risk.

First batch of Semis will be delivered in phases, with 300 trucks going into WattEV’s electrification plan

According to the contract, the first batch of 50 Tesla Semis is expected to begin delivery in 2026, while the remaining vehicles will be deployed gradually by the end of 2027. More than 300 of them will be used in WattEV and the Port of Oakland’s joint electrification program to support port drayage and regional freight routes, aligning closely with California’s policy goals of freight decarbonization.

WattEV itself also has hands-on experience operating electric trucks. Previously, the company accumulated millions of miles of electric truck operating experience in Southern California, including early participation in Tesla Semi pilot programs deployed at the Port of Los Angeles and the Port of Long Beach—laying a solid operational foundation for this large-scale expansion.

Megawatt-class charging network built in parallel; 30 minutes to add 300 miles of range

The key to supporting this large-scale deployment lies in advancing the charging infrastructure buildout in sync. WattEV plans to build megawatt charging system (Megawatt Charging System, MCS) hub stations in places including Oakland, Fresno, Stockton, and Sacramento. Each charging session takes about 30 minutes to add roughly 300 miles of range, making the recharging time comparable to the time required for traditional diesel trucks to refuel.

Among them, the Oakland charging station has recently officially started construction. As a core node connecting Northern California and Central California freight corridors, the station links the port with inland logistics hubs. Building this charging network will also be an important incentive to attract more fleet operators to adopt electric trucks in the future.

Tesla Semi production ramps up; the industry is optimistic about the outlook for electric freight trucks

Currently, Tesla Semi is actively increasing capacity at its Nevada factory, aiming to significantly boost shipment volume in 2026. Multiple fleet operators across the US have given Tesla Semi high marks based on real-world operations, highlighting strong torque, operating costs significantly lower than those of diesel vehicles, and advanced active safety features.

Industry observers point out that as diesel trucks face dual pressures—rising fuel costs and increasingly stringent regulations—operators offering “turnkey” electric solutions like WattEV are expected to substantially lower the conversion threshold for freight operators, thereby accelerating the overall market’s electrification.

For California, this project will help improve air quality around ports and major roadways, and provide a replicable infrastructure blueprint for heavy-vehicle electrification. For Tesla, this order not only demonstrates its expanding influence in the commercial vehicle market, but also symbolizes that electric trucks are formally crossing the testing stage and entering a new era of scaled commercial deployments.
