Análise e ajuste contratual em uma unidade consumidora do grupo A: estudo de caso

Abstract

This work addresses the analysis of the electrical energy usage pattern at Supermercado Alves in search of energy optimization opportunities. Using Excel software as a tool, our methodology involved an assessment of two periods, examining energy bills records, with the aim of profiling the supermarket's consumption. Subsequently, we applied technical criteria for contractual adjustments to minimize financial waste. These adjustments included obtaining an appropriate contracted energy demand and the installation of photovoltaic panels for increased energy savings. Our research also included comparisons among three tariff options: Horo-Sazonal Verde, Horo-Sazonal Azul, and Optante B, where, in the case of the latter option, the use of the diesel generator would no longer be necessary. Our studies highlighted that the tariff change can lead to significant savings in the supermarket's electricity bills. It is worth noting that the establishment does not encounter low power factor issues. The results obtained demonstrate the need for studies focused on electrical energy optimization, including a more in-depth examination of contractual regulations. To validate the study's efficiency, tables and graphs with in-depth monthly analyses were conducted. These can provide viable alternatives to reduce energy consumption and assess its economic feasibility.
