Investigated the peaking phenomenon, the tendency for electrical energy users to consume at high rates for brief periods during the day, by analyzing the electrical energy consuming behavior of 3 families. A continuous data collection system to monitor consumption of electrical energy was installed in the homes of the families. Information, feedback, and incentives were evaluated for their effects on peak energy consumption. A combination of feedback plus incentives was most effective and reduced peaking about 50%. Removal of experimental treatments resulted in a return to pretreatment patterns of consumption.
