ABSTRACT
Truck Stop Electrification (TSE) is an approach currently being deployed to reduce heavy truck idling at truck stops
and rest areas. Drivers of the nearly 500,000 long-haul trucks in the United States must rest for specific periods
prescribed by the U.S. Department of Transportation’s Hours of Service regulation. Long-term idling is prevalent in
the heavy truck sector to provide heating and cooling to the sleeper cab. However, idling increases fuel and
maintenance costs, emissions, and noise. Recognizing this, local jurisdictions have developed regulations to restrict
long-term idling. Popular options to reduce idling include auxiliary power units and fuel-fired heaters. Both have
significant operational, environmental or cost disadvantages compared to TSE. TSE is the preferred approach to
anti-idling because of zero on-site air emissions and minimal noise emissions. The paper reports on the path to the
current state of the industry, ongoing TSE activities, and analysis of data collected from commercial TSE facilities
to determine the technology’s environmental impacts. The results indicate that TSE can significantly reduce on-site
emissions as well as net airshed emissions.
