Locations for truck stop electrification (TSE) have previously been determined by economic factors (where the installations can be subsidized by government agencies and where providers of this technology can generate the most revenue). These locations may not necessarily coincide with the optimum locations from a national perspective, which includes factors such as the development of a network of TSE facilities, locations that would have the greatest potential of reducing idling and, locations where the reduction in emissions would have the greatest benefit. The goal of this project was to develop and apply a methodology to identify optimum locations for deploying TSE sites across the nation. A total of 15 major truck corridors along the interstate system of the U.S. were identified and prioritized using criteria such as corridor length, major activity centers, truck volume, truck growth rates, nonattainment areas, existing TSE sites, number of truck stops, average temperatures, and major intersections. Each corridor was divided into sections or zones of approximately 20 miles in length that were also prioritized using the same criteria. Based on zone rankings and spacing criteria, a set of primary and secondary zones were identified for installing TSE facilities along each corridor. After determining the zones for implementation, it would be up to the TSE providers to negotiate deals with the truck stops within those zones (only one truck stop per zone should be implemented). This research provides both an approach and optimum locations for implementing TSE sites across the nation.
