Truck Stop Electrification for Heavy-Duty Trucks

Truck stop electrification reduces fuel costs and diesel emissions.

Electrified parking spaces (EPS), also known as truck stop electrification (TSE), provide truck drivers necessary services, such as heating, air conditioning, or power for appliances, without the need for engine idling.

The U.S. Department of Transportation (DOT) estimates there are about 5,000 truck stops in the United States. Options for truck stop electrification include single-system electrification and dual-system electrification, also known as "shore power."

Single-System Electrification

In single-system electrification, off-board equipment at the truck stop provides internet access, heating, ventilation, and air conditioning (HVAC). These HVAC systems are contained in a structure above the truck (called a gantry) or on a pedestal beside the truck. A hose from the HVAC system is connected to the truck by a window adaptor and, in some cases, to a computer touch screen that enables payment.

These stand-alone systems are generally owned and maintained by private companies that charge an hourly fee. To accommodate the HVAC hose, an inexpensive window template may be required in the truck.

Dual-System Electrification

Dual-system electrification, also known as "shore power," requires both onboard and off-board equipment so trucks can plug in to electrical outlets at the truck stop. To use dual-system electrification, trucks must be equipped with AC equipment or an inverter to convert 120-volt power, electrical equipment, and hardware to plug in to the electrical outlet. Necessary electrical equipment might include an electric HVAC system.

Truck stop outlets are owned by the truck stop or by a private company that regulates use and fees. The truck owner or trucking company owns and maintains the onboard equipment.
