Electric trucking company WattEV has placed an order for 370 Tesla Semi Class 8 trucks — the largest single electric truck deployment in California history, valued at approximately $100 million. The first 50 units are scheduled to arrive in 2026, with the full fleet operational by the end of 2027.
Port of Oakland at the Center
More than 300 of the 370 ordered Semis will be deployed under a joint program with the Port of Oakland, electrifying drayage and regional freight routes across Northern and Central California. WattEV selected the Tesla Semi after running a public request for proposals process, ultimately choosing it based on cost, performance, and availability — a meaningful signal that Tesla's Class 8 truck is competitive on commercial procurement terms, not just spec sheets.
The remaining trucks will serve regional freight corridors, extending WattEV's footprint beyond its existing six operational depots in Southern California.
Charging Infrastructure Comes With It
The order isn't just about trucks. WattEV is building out the charging backbone to support the fleet, with new truck-charging stations opening at the Port of Oakland and in Fresno. Both locations will be equipped with Tesla's Megawatt Charging System (MCS) — capable of delivering roughly 300 miles of range in about 30 minutes. Additional depots are planned for Stockton later this year, with Sacramento breaking ground in 2026.
WattEV operates on a "Truck-as-a-Service" (TaaS) model, bundling vehicle deployment, megawatt-class charging infrastructure, and full-service leasing into a single offering for freight operators. That model lowers the barrier for fleet operators who don't want to manage charging infrastructure themselves — and it puts Tesla Semi in front of customers who might otherwise have stayed on diesel.
Why This Order Matters for Tesla Semi's Momentum
The timing is significant. Tesla Semi is now entering mass production, with high-volume manufacturing underway at a dedicated factory adjacent to Gigafactory Nevada. A 370-unit commercial order — structured with real delivery milestones rather than vague commitments — is exactly the kind of demand signal that justifies that production ramp.
California's drayage market is one of the most scrutinized in the country from a regulatory standpoint, with the California Air Resources Board pushing hard toward zero-emission requirements at ports. WattEV's deployment at Oakland puts Tesla Semi directly in the path of that regulatory tailwind, and a successful execution here would be a visible proof point for fleet operators watching from the sidelines.
With deliveries beginning next year and the full fleet expected online by late 2027, this deal gives Tesla Semi a concrete commercial timeline to point to — and WattEV a first-mover position in one of the most strategically important freight corridors on the West Coast.
