WattEV orders 370 Tesla Semis in largest California EV truck deployment

WattEV announced an order for 370 Tesla Semi Class 8 electric trucks, making it the largest single electric truck deployment in California. More than 300 of the trucks will be deployed under a joint program with the Port of Oakland.

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, marking a significant early win for Tesla’s commercial truck ambitions.

From Nikola to Tesla

WattEV is no stranger to electric trucking. The company was one of Nikola’s biggest commercial customers, taking delivery of 14 Nikola Tre BEV trucks in May 2023 and purchasing an additional 22 units later that year — totaling at least 36 Nikola electric trucks in its fleet.

That bet didn’t age well. Nikola filed for Chapter 11 bankruptcy in February 2025 and was down to a single employee by December 2025. The company’s remaining hydrogen truck assets were acquired by Hyroad Energy in a bankruptcy auction.
