The objective of this research is to discuss the conceptual basis and define the criteria for the installation of a Centralized measurement system in the Baixada Fluminense, concession area of the electricity utility of Rio de Janeiro (Light). The study estimates the energy consumption and the average revenue that results from the implementation of the proposed facility to replace the traditional measurement system in place. The sub area of concession selected was defined based on the following two characteristics: area associated with high rate of electricity losses and vulnerability of the power grid exposed to the community. The methodology used to develop the work included a literature review on systems of electricity metering and a study of the socioeconomic profile of the selected region. The impact of the proposed technological change on the energy consumption was statistically evaluated based on the nonparametric Wilcoxon test. Based on real data from municipalities located in the region, an analysis of energy consumption behavior was carried out before and after the technology alternative was implemented.
