Fleet Charging Corridors

node spacing · MCS · Texas Triangle · AFIR

A truck corridor is a chain of depots spaced to the truck's real range. Most US freight lanes are shorter than one Semi charge, so the first corridors need few nodes, but each one needs a substation's worth of power.

Freight lane lengths compared with electric truck range: Ports of Los Angeles and Long Beach to the Inland Empire about 60 miles; Houston to San Antonio on I-10 about 200 miles; Houston to Dallas on I-45 about 240 miles; Dallas to San Antonio on I-35 about 275 miles; Los Angeles to Phoenix on I-10 about 370 miles; Laredo to Dallas on I-35 about 430 miles. Reference lines mark the Tesla Semi Standard Range of about 325 miles and Long Range of about 500 miles. The three Texas Triangle legs fit within one charge of a Long Range Semi. One 30-minute stop on a 1.2 MW charger adds roughly 300 miles to a loaded Class 8 truck, and US hours-of-service rules already require a 30-minute break after 8 hours of driving.

Finding

Electric truck corridors are a spacing problem solved by the driver's mandatory break, and the binding constraint is megawatts at each node

US hours-of-service rules require a 30-minute break after eight hours of driving, and a 1.2 MW Megacharger delivers roughly 600 kWh in that time, about 300 miles for a loaded Class 8 truck at 1.7-2 kWh per mile. Each leg of the Texas Triangle is 200-275 miles, inside one charge of a Long Range Tesla Semi.

So a corridor needs nodes at the lane ends and one or two in between for resilience, not a charger every exit. The hard part is power. A node with four to eight megawatt stalls draws 5-10 MW, a medium-voltage service that takes one to three years to deliver in most US utility territories. That is why corridors form around depots that already exist - port drayage yards, Tesla and Pilot truck stops, Greenlane's sites - rather than as single planned projects. The federal National Zero-Emission Freight Corridor Strategy (2024) staged hubs from ports outward, but funding and rules have since been pulled back, and private operators now set the pace.

Europe legislated its corridor: the Alternative Fuels Infrastructure Regulation (AFIR) requires truck charging pools of at least 3,600 kW every 60 km on the TEN-T core network by 2030, and Milence, the joint venture of Daimler Truck, Traton and Volvo, is building to it. China built corridors around battery swap on fixed heavy-haul routes. Texas, with Greenlane on I-45, Tesla Megachargers on I-10 and the most planned Semi sites of any state, is where a US regional corridor is closest to complete - see Texas EV charging infrastructure (AustinIO).
