WattEV Orders 370 Tesla Semi Electric Trucks in $100 Million Deal

Tesla has landed one of the biggest orders yet for its Semi electric truck. WattEV, a company building out electric freight services and charging infrastructure in the US, announced it is adding 370 of the electric big rigs to its fleet. The deal is worth an estimated $100 million, and the project represents one of the largest rollouts of Class 8 electric trucks in California.

Deliveries are set to begin in 2026 with the first 50 Tesla Semi units, and the entire fleet should be in service by the end of 2027. More than 300 of these trucks are earmarked for a program tied to the Port of Oakland, moving goods between the port area and regional logistics routes. In this kind of operation, fast charging matters just as much as the trucks themselves.

WattEV is already rolling out a network of charging depots across California. At its Port of Oakland site, the company says it can charge up to 25 medium- and heavy-duty electric trucks simultaneously at up to 240 kW—or six trucks at up to 1.2 MW. That infrastructure is designed to slash charging downtime to roughly 30 minutes.

For Tesla, this order is a big deal because Semi deliveries have been limited so far. The company highlights that the truck can recoup up to 60% of its range in 30 minutes and that its three electric motors provide the muscle for heavy hauling. Still, the real question is when high-volume production will kick in: earlier reports have indicated that mass production of the Semi in Nevada is slated to ramp up in 2026.
