Massive Order for Tesla Semi Signals Shift Towards Electric Truck Adoption
Trucks are accelerating their journey towards electrification, and Tesla has made a significant move with the unveiling of its Semi. Following this momentum, Catalyst Mobility (formerly CALSTART) and Smart Freight Centre have announced an order of 2,500 vehicles from Elon Musk’s brand, though the exact number of Semis remains unknown. This marks the largest electric truck order ever placed in the United States.
ZET SCALE Alliance Drives Demand
Both companies will acquire these electric trucks through ZET SCALE (Zero-Emission Truck Shipper-Carrier Alliance Leading Electrification), a program jointly managed by the organizations. Founding members of the alliance include Microsoft, Red Bull, and PepsiCo, with a stated goal of surpassing 10,000 trucks.
Mercedes-Benz has also secured a deal, selling 50 electric eActros 600 trucks (545 hp and 500 km range) to Amazon, slated to begin operation this year. This could be a crucial step forward in decarbonizing heavy road transport, potentially sparking a wider adoption trend.

Tesla’s New Factory and Competitive Selection
Tesla recently inaugurated the plant in Sparks, Nevada, dedicated to manufacturing its electric trucks, with plans to produce 50,000 annually. According to ZET SCALE, Tesla consolidated transportation volumes from its associated companies and initiated a competitive bidding process for vehicle supply. “You can have good technology and still not have a market,” stated Michael Berube, President and CEO of Catalyst Mobility. “What differentiates ZET SCALE is that demand was organized so that manufacturers could price at scale. That’s how costs come down and clean trucks move beyond the pilot phase.”
However, the alliance clarified that Tesla wasn't the sole or initial option. They evaluated various offers based on price, range, payload capacity, and production capabilities. Dan Priestley, Tesla Semi Program Director, stated, “The Tesla Semi is designed to offer a lower cost per kilometer than a diesel truck.”

Alternative Manufacturers and Environmental Concerns
ZET SCALE’s objectives are particularly compelling as they amplify the cost operational advantages and predictability offered by electricity on a large scale. Kenworth, RIDE, and Volvo were designated as alternative manufacturers for carriers requiring different vehicle types. Catalyst did not specify how many of the 2,500 trucks will be Tesla Semis. Environmental organizations like Natural Resources Defense Council (NRDC), Sierra Club, and Transport & Environment used the announcement to urge.
