Purpose: The objective of this research was to examine the relative efficiency of the economic and financial performance of Brazilian open and closed energy distribution companies.  Methodology: This research is classified as descriptive, quantitative and documentary. As a strategy of the study, data envelopment analysis - DEA, BCC model, focusing on results was adopted. The sample consisted of 33 DMU's represented by the large electric power distribution companies that were in operation in 2017. Results: The results obtained indicate that 9 (27.27%) among the 33 companies reached the efficiency frontier and that, among these, only 2 were publicly held companies, however, these two alone were references more often to the inefficient ones, accounting for 50 , 8% of benchmarks. Among the nine efficient companies, seven (77.78%) are closed companies, revealing that the IPO was not a determining factor to achieve economic efficiency, however, once such efficiency is achieved, the practices of the two public companies may be most inefficient companies. Contributions of the Study: Previous studies involving data analysis in the electric power sector did not consolidate in the same efficiency study all four profitability indicators studied in Matarazzo (2010). Therefore, this research allowed to increase the knowledge about the study of efficiency from economic indicators using data envelopment analysis. Considering still relevant the analysis of efficiency focusing on economic performance, which consists of the indicators of profitability, either for the shareholder through the analysis of ROE and ML or for the managers of the companies, through ROA and GA, which ends up being relevant to society, given the indispensability of this economic segment in any community
