Abstract
Retard energy regenerated from an electrical motor during braking action is reinjected into a power system via trolley lines. The retard energy may be transmitted to a bidirectional electric substation and returned to a utility grid. The retard energy may also be transmitted to an auxiliary energy storage system, such as an ultracapacitor system or a battery system. Installing trolley lines for mining haul trucks on a downhill slope may be used to capture and re-use substantial quantities of retard energy.
