WattEV is expanding its electric truck charging network with the development of three new depots in California. The projects are supported by more than $24 million in state grant funding aimed at improving heavy-duty freight electrification infrastructure.

Depot Locations

The new charging sites are under development at the following locations:

  • Otay Mesa: Near the U.S.-Mexico border in San Diego County

  • Baker: Along the I-15 corridor between Southern California and Nevada

  • Port of Long Beach: Expanding capacity at the container port

Together, the sites will add 29 Megawatt Charging System (MCS) units. The stations are expected to handle approximately 100,000 charging sessions per year. Funding is provided through a program from the California Transportation Commission to develop zero-emission freight infrastructure along high-traffic corridors.

“The inflection point in freight electrification is arriving with the introduction of trucks capable of megawatt charging at scale,” said Salim Youssefzadeh, CEO of WattEV. “We see 2026 as the turning point, and we are building ahead of demand to ensure that all major freight corridors in California are ready.”

Site Details

  • Otay Mesa (7 MCS chargers): Located less than 1,000 feet from the U.S.-Mexico border in a high-traffic international trade area. Developed with San Diego Gas & Electric (SDG&E), the site is intended to support frequent cross-border freight activity.

  • Baker (10 MCS chargers): Positioned along I-15 to serve long-haul freight traffic between Southern California and Las Vegas. Development is in partnership with Southern California Edison (SCE).

  • Port of Long Beach (12 MCS chargers): Adds new charging capacity at one of the country’s largest cargo hubs. The installation features Silicon Carbide-based medium-voltage power rectifiers developed by WattEV’s technology division, Charge America. The use of proprietary Solid-State Transformer (SST) technology removes the need for traditional step-down transformers, which may lower installation costs and simplify site development. Charging cabinets are installed between lanes in a layout similar to conventional diesel fueling stations.

Each location is designed to support vehicle charging times of 30 minutes or less. Their placement is intended to align with regional transportation and freight movement strategies.
