Tesla Semi Fleet Orders Surge: WattEV Commits to 370 Electric Trucks for Port of Oakland

In a major milestone for electric trucking, WattEV has placed an order for 370 Tesla Semi trucks—the largest single order for the battery-powered heavy-duty vehicle to date. More than 300 of these units are specifically allocated to a joint zero-emission program with the Port of Oakland, signaling a rapid shift toward sustainable freight logistics.

"This order reflects the growing confidence in the Tesla Semi's performance and its ability to meet the rigorous demands of port operations," said Mike Roeth, executive director of the North American Council for Freight Efficiency. "The scale of this deployment will provide invaluable real-world data on total cost of ownership and charging infrastructure."

The Deal at a Glance

WattEV, a California-based electric truck fleet operator, confirmed the order in a statement released Tuesday. The trucks are expected to begin deliveries in early 2024, aligned with Tesla's ramp-up of Semi production at its Nevada Gigafactory.

"Our partnership with the Port of Oakland is designed to demonstrate that zero-emission trucking is viable today," said WattEV CEO Salim Youssefzadeh. "With over 300 Tes Semis in their drayage fleet, we can cut thousands of tons of CO2 annually."

Background

The Tesla Semi was first unveiled in 2017 and has seen numerous production delays. Tesla officially handed over the first production units to PepsiCo in December 2022, but volume manufacturing only began in late 2023. The Class 8 truck boasts a range of up to 500 miles on a single charge and can accelerate to 60 mph with a full 82,000-pound load in 20 seconds.

The Port of Oakland has been under pressure to reduce emissions from its drayage operations, which account for a significant portion of local air pollution. The port's Seaport Air Quality 2020 and Beyond plan aims to transition to zero-emission trucks by 2030. The WattEV order represents a critical step toward that goal.

WattEV already operates a fleet of electric trucks, including the Kenworth T680E and Peterbilt 579EV, but the Tesla Semi order marks its biggest commitment. The company is also building a network of charging depots in Southern California and the Bay Area to support these trucks.

What This Means

The order underscores a pivotal shift in the freight industry. With over 370 units on order, Tesla's Semi program is moving beyond pilot programs into mass deployment. "This is not a trial—it's a commercial-scale operation," said John Gartner, a senior analyst at Guidehouse Insights. "If WattEV can operate these trucks profitably, it will open the floodgates for other fleets."

The concentration of trucks at the Port of Oakland also creates a dense charging ecosystem. WattEV and the port plan to install multiple megawatt-level chargers capable of replenishing the Semi's battery in under an hour. This infrastructure could serve as a model for other port cities.

For Tesla, the order validates its heavy-truck strategy. The company has struggled to produce the Semi at scale, but CEO Elon Musk recently stated that the factory is "running at full speed." With WattEV's commitment, Tesla has secured enough orders to keep the line busy for months to come.

However, challenges remain. The high upfront cost of electric trucks—estimated at over $200,000 for the Semi—requires significant subsidies or operational savings to make economic sense. WattEV is leveraging state and federal grants, including funds from the California Air Resources Board, to offset costs. The success of this program will depend on the reliability of the trucks and the charging network.

"The real test will be in daily operations," said Gartner. "Can these trucks handle the stop-and-go of port traffic, the weight of containers, and the heat of California summers? If they can, this order could be a turning point for the entire industry."
