With CARB-certified Class 8 battery electric trucks (BETs) now commercially available, understanding large-scale fleet deployment is critical. JETSI is among California’s first pilot projects to demonstrate the feasibility of deploying at least 50 BETs within a single fleet. The project offers valuable lessons for scaling zero-emission technologies. The trucks will achieve at least 150–200 miles per charge, operating primarily in drayage and short regional haul services. Support systems include charger management software, demand response, uptime services, maintenance plans, and solar-plus-storage solutions. South Coast AQMD leads this regional effort with MSRC, SCE, and the ports of Los Angeles and Long Beach. Fleet partners NFI and Schneider will each deploy 50 trucks; NFI will also install 1 MW of solar and 7.7 MWh of battery storage.
