The aim of this work discusses basic concepts associated with the load factor (LF) and demand factor (DF) and the adequacy of their use by electricity utilities. The knowledge and management of these electrical parameters is rather important, as they contribute for the improvement of the efficiency and security of the system as a whole while promoting reduction on energy costs. The method used to estimate these quantities is based on the Chauvenet statistical tests capable to detect and remove possible discontinuity on the sample data observed to follow normal distribution. The LD and DF were estimated for various clusters of similar clients of a given distributing utility. Estimations were obtained through a survey involving clients of the selected utility to capture information on the end-users and their nominal power demanded at both, the low and high voltage levels. In parallel to the survey, the utility measured and monitored the energy consumption of the clients participating in the study. As a conclusion, the study revealed that the electricity utilities do not have access to update information (stratified by segments of clients) on the electrical parameters. A dynamic scheme to make available updated information related to load factor and demand factor proved to be extremely useful and is highly recommended.
