San Diego Gas & Electric (SDG&E) says the maiden voyage of their Class 8 heavy-duty electric semi marks the first time an electric semi has crossed the border hauling a standard load, marking an important milestone as the two nations move toward a net zero future.

The electric semi truck – one of 11 Peterbilt 579EV Class 8 trucks bought by San Diego-based Bali Express last year – made its first trip to Mexico carrying an unspecified load of goods through the Port of Entry at Otay Mesa, which connects Southern California to the city of Tijuana, Mexico.

Bali Express’ electric trucks will utilize SDG&E’s recently activated HD charging infrastructure to provide “reliable and affordable” electric freight options for medium and heavy-duty EVs crossing the US/Mexico border.

The SDG&E-powered chargers were partially funded through a $200,000 grant from the California Energy Commission’s Clean Transportation Program. That program has put more than $1 billion to alternative fuel and vehicle technology projects designed to improve public health while bringing both environmental and economic benefits to communities throughout the state.

Those sentiments were echoed by San Diego Mayor Todd Gloria. “The historic crossing of this electric freight truck symbolizes San Diego’s commitment to innovation, cross-border cooperation and our binational community,” said Gloria, in a statement. “We’re not just reducing emissions, we’re building a cleaner future for people living near our border, and leading the way in international trade and environmental responsibility.”

Meanwhile, Executive Director of SDG&E Caroline Winn called the new charging corridor, “an example of how collaboration can create new and innovative ways to rethink how to move transportation systems toward electrification.”

The Peterbilt 579EV trucks have an 82,000 lb. GCWR and is powered by the same 670 hp Meritor 14Xe “epowertrain” used in the PACCAR Kenworth t680e that debuted back in 2022. That system integrates electric motors and drive axles into a single unit, making it easy for manufacturers to electrify their fleets by maintaining existing (re: ICE) axle mounting hardware.

The big Petes have approx. 150 miles of range and are capable of fully charging their massive, 400 kWh batteries in about 3 hours.

Electrek’s Take

The California Air Resources Board (CARB) has approved a landmark plan to end the sale of gas-powered vehicles by 2035. And, while California is just one state, it’s important to remember that, as California’s fleets go, so too go the fleets of Mexico, Arizona, Colorado, Washington State, and others.

If we’re lucky, the whole country will be electric-only well before then.
