Idle Reduction Projects in Kentucky

Mercer Transportation, Heavy Duty Trucking

Louisville, KY

Headquartered on 14 acres in downtown Louisville, Kentucky, Mercer Transportation Company operates throughout the continental United States, Canada and interline service to and from Mexico offering flatbed, dry van, drop deck and special equipment.  Mercer Transportation manages the deliveries of approximately 2,000 class 8 tractors and trailers.  Over 75% of these heavy-duty diesel trucks use plug-in electric auxiliary power units while stopped in Mercer’s downtown Louisville location, reducing engine idling, saving fuel, and improving the city’s air quality.  This on-site power provides interior truck power and ac/heating eliminating diesel engine idling.

There are 49 electrical outlets on the Mercer property, enabling long-haul drivers to plug in their trucks rather than run their engines to power their electrical systems.  This on-site power provides interior truck power and ac/heating eliminating diesel engine idling. Mercer also encourages its drivers to invest in auxiliary power units so they never need to idle, even when parked somewhere inaccessible to an electric outlet.
