A new analysis from the International Council on Clean Transportation (ICCT) forecasts a sharp increase in charging infrastructure requirements for zero-emission medium- and heavy-duty vehicles (ZE-MHDVs) in the United States, updating its first national estimates published in 2023.
The July 2025 report uses updated traffic, technology, and policy data to project needs for 2030 and 2035 under three adoption scenarios—Reference, Compliance, and Market Potential—reflecting low, moderate, and high levels of electric truck uptake.
Under the moderate Compliance scenario, the U.S. will need nearly 180,000 chargers to support about 411,000 electric trucks by 2030. That number climbs to 586,000 chargers for 1.49 million vehicles by 2035, requiring daily electricity consumption to quadruple from 40,600 MWh to 151,000 MWh. Overnight chargers, typically lower-powered units installed at depots, are expected to make up about 565,000 (96%) of installations, though fast and ultrafast public charging will remain essential for long-haul operations.
The study identifies major "hot spots" for charging demand along key freight corridors, especially in California’s Inland Empire, the Phoenix metro area, and eastern Texas. California alone could account for 21% of national ZE-MHDV energy needs in 2030.
Even in the most conservative Reference scenario, fleets would require more than 130,000 chargers and 9,500 MW of nameplate capacity by 2030. In the most aggressive Market Potential scenario, the country could need 960,000 chargers by 2035.
ICCT warns that multi-year grid upgrades will be critical, particularly for facilities exceeding 2 MW capacity. It also stresses that strategic siting balancing public charging between truck stops and commercial fueling sites could reduce strain on local utilities and speed deployment.
The findings underscore the urgency for utilities, regulators, and fleet operators to coordinate investments to ensure the nation’s charging network can meet the accelerating pace of truck electrification.
