This paper comprises a suggested modus operandi to analyze the efficiency of the Brazilian electrical sector distributing companies based on the econometrics study of information and data that directly affect distributing companies´ efficiency, such as operational cost, amount of employees, energy volume supplied, and some qualitative indicators, such as percentage of energy losses, average duration of the supply suspension to the consumer per year in hours (DEC) and average quantity of the supply suspension to the consumer in a year (FEC). Besides these, some social-economic indicators are considered, such as monthly income and demographic density of each company. House electrical devices and a privatization's dummy variables were also created. The analysis starts with the definition of production and cost frontiers, followed by the study of variables that have an influence on each of these and estimation of the production and cost frontier functions, through the Stochastic Frontier Method.
