The experimental approach for the service quality of electricity is represented in this paper for better insight of its determinants. This approach is particularly used to segregate the different aspects of electricity services in the National Capital Region. EFA as an independent method is used to filter out the dimensions of service quality. The five dimensions of service quality are chosen and data are collected by two step questionnaire, a set of two hundred responses is selected randomly. Although, this study is confined to electricity services provided by electricity companies in NCR, the study provides an excellent scope for the researchers to explore different areas of service quality.
