WattEV has ordered 370 Tesla Semi Class 8 electric trucks, making it the largest single electric truck deployment in California. The order comes just days after the first Tesla Semi rolled off the high-volume production line at the new dedicated factory adjacent to Gigafactory Nevada. Over 300 of the trucks will be deployed under a joint program with the Port of Oakland. The announcement was made at the ACT Expo trade show in Las Vegas. The first 50 Tesla Semis are scheduled to start in 2026, with the full fleet operational by the end of 2027. This order signals a commercial validation for Tesla's Semi program.
