Avaliação dos custos adicionais das faturas de energia elétrica devido ao seu uso irracional.

Abstract

A methodology to analyze electric energy bills, based on the Brazilian legislation, is presented. The objective is to persuade consumers to use electric energy economically and rationally. Emphasis is given to power factor regulation, energy demand taxation and the effect of load factor on the energy costs. The analysis of the historical data is one of the most important topics of energy management. In this respect, the electrical energy bills, which present a synthesis of data inherent to its use, constitute an essential management tool. The methodology is applied to the analysis of 170 consumer bills. The analysis shows that several consumers could have reduced their costs by more than 50%.
