Planejamento de Redução de Custos Para Energia Elétrica Por Meio de Uma Análise Multicritério de Eficiência Energética: Um Estudo de Caso Para Um Centro Universitário

Abstract

The analysis of the electric bill, in many situations, is neglected by many consumers who adopt incorrect structural tariff modalities and other factors, causing electric bills with high values. The multicriteria analysis facilitates the cost reduction of the consumer's electric bill, which results in several fields of work related to energy efficiency, seeking reduction in the referred invoice, being able to have a discount of up to 100% of the total value, freeing the consumer to deal with electricity bills. The criteria covered in this article are the correct demonstration for choosing the tariff flag, the correct use of capacitor banks to adjust the power factor and the implementation of a photovoltaic system "on grid". This study shows the energy efficiency analysis methodology applied in a University Center, showing that it is possible to reduce annual expenses on the electricity bill by 63.72%
