Abstract:

Energy efficiency is defined differently for various purposes, making calculating end-user energy efficiency controversial in the context of demand-side management. One fundamental issue is that pure measurements of energy efficiency cannot be obtained without influence from confounding factors (i.e.: weather or equipment maintenance). Thus, several efficiency index decomposition analysis methods have been used to remedy the lack of uncontaminated data. However, most index decomposition analysis is done at an industrial level, which provides a better-controlled environment than that of the end user's level. Required information at an end user's level is much more difficult to collect making index decomposition analysis impractical. As the result, evaluation of energy efficiency associated with demand-side management programs becomes subjective. An assessment of whether the energy savings and actual peak load reduction varies by instituting demand-side management programs or not, and how different types of customers respond to them, is proposed in this study by using supplemental statistical analysis to reduce the influence of unwanted confounders.
