WattEV announced on Tuesday the deployment of 370 Tesla Semi trucks, marking the largest single electric truck order in California history and representing a revenue of approximately $100 million.
The first 50 units are scheduled for delivery in 2026, with the full fleet expected to be operational by the end of 2027.
The announcement was made by WattEV’s CEO Salim Youssefzadeh, at the annual ACT Expo industry trade show in Las Vegas.
“We selected the Tesla Semi based on cost, performance and availability after issuing a public request for proposals,” Youssefzadeh said.
He highlighted that the move came as the Tesla Semi is “entering mass production and drawing strong reviews from fleet operators nationwide.”
WattEV’s vertically integrated model – combining vehicle deployment, megawatt-class charging infrastructure, and full-service leasing – offers “a turn-key path for carriers without any capital risk,” the CEO noted.
The Long Beach-based company is a provider of heavy-duty truck charging infrastructure and electric Trucks-as-a-Service (TaaS) — offering fleet operators access to zero-emission vehicles without requiring upfront capital investment.
The company previously operated Nikola battery-electric trucks, purchasing a combined 36 units from the now-bankrupt Arizona-based manufacturer across 2023 and 2024.
Port of Oakland Partnership
More than 300 of the Tesla Semis will be deployed under a joint program with the Port of Oakland, anchoring zero-emission freight operations across key California corridors.
Delivery of the first 50 units coincides with WattEV’s planned opening of truck-charging stations at the Port of Oakland and in Fresno, both equipped with Tesla‘s Megawatt Charging System (MCS) chargers.
The company says the MCS chargers are capable of providing 300 miles of range to a Semi in approximately 30 minutes, comparable to a conventional diesel fill-up.
Additional depots are scheduled to open this year in Stockton, with a Sacramento location breaking ground in 2026.
The charging hub buildout aligns with Tesla‘s own expansion of its Megacharger network.
The company deployed its first public Megacharger in Southern California earlier this year.
Additionally, US fuel retailer Pilot Travel Centers has announced plans to install Tesla Semi chargers at travel centers along major US highways, with initial locations planned across California, Georgia, Nevada, New Mexico, and Texas.
Growing Fleet Interest
The WattEV order comes days after California-based Forum Mobility confirmed a 40-unit Tesla Semi order from freight operator Big F Transport, which will operate the trucks from a depot in Rancho Dominguez expected to open in the first quarter of 2027.
Both announcements follow the first Tesla Semi rolling off the high-volume production line at Gigafactory Nevada last week, marking the transition from pilot builds to industrial-scale manufacturing.
The Semi is being built at a dedicated 1.7-million-square-foot factory adjacent to Gigafactory Nevada in Sparks, designed for an annual capacity of 50,000 trucks.
Tesla has signalled that the ramp will be gradual.
“You should expect that initial production of Cybercab and Semi will be very slow, but then ramping up, and going exponential towards the end of the year and certainly next year,” CEO Elon Musk said during the company’s first-quarter earnings call.
The order adds to a growing list of fleet commitments for the truck.
DHL confirmed an order beyond “just a handful” of Semis for 2026 delivery, while AiLO Logistics and Mone Transport have recently completed operational pilots with positive efficiency results.
DHL Supply Chain reported energy consumption of 1.72 kWh per mile on a fully loaded 390-mile route, while ArcBest logged 4,494 miles over three weeks at 1.55 kWh per mile.
A separate cross-country test by Mone Transport recorded 1.64 kWh per mile across 4,700 miles.
Second-Gen Semi
The Tesla Semi entering volume production is a significantly updated version compared to the original units delivered to PepsiCo in late 2022.
The second-generation truck sheds roughly 1,000 pounds compared to its predecessor and achieves 1.7 kWh per mile — a 15% efficiency improvement — while maintaining a 500-mile range.
The truck delivers 800 kW of drive power and supports peak charging speeds of 1.2 MW, with Tesla stating that the majority of its range can be recovered in a 30-minute charge session.
Tesla‘s Semi is rated for a gross combination weight of 82,000 lb. (37,195 kg) and a range of up to 500 miles (805 km) on a single charge.
The truck is present at the ACT Expo event, held in Las Vegas this week.
Tesla owner David Moss, who attended the event, shared on X that he was able to ride in the production version of the Semi.
Moss, who visited the display featuring both Standard Range and Long Range models, shared photos and a short interior video from the cab.
While Moss was not allowed to record video during the ride itself, his posted images and brief cabin footage provide one of the clearest public looks at the production Tesla Semi’s interior to date.
According to his posts, the large central touchscreen displays vehicle status information, including charge level and remaining range, alongside a full navigation map, multiple camera feeds, and various controls.
He also highlighted the Tesla-branded steering wheel, standard pedal layout, power-adjustable driver’s seat, dual sun visors, multiple coat hooks, and a large mono wiper.
