Eficiência energética empregando as modalidades tarifárias para obter economicidade: estudo de caso em instituição pública de ensino

Abstract

This work aims to study a specific case of a consumer unit from the public sector, IFG Valparaíso de Goiás campus, regarding the costs of electrical energy based on tariff modalities to meet the principles of economy and energy efficiency in the appropriate use of electrical energy. The study proposes to determine the best tariff classification for IFG in Valparaíso de Goiás (IFG-VAL). The proposed methodology involved analyzing the contracted demand, consumption, and associated costs graphically using the MATLAB software, based on the consumption history of the last 14 months and the costs of possible tariff classifications. From this scenario, it was possible to understand the cost-benefit relationship of tariff modalities, simulate future scenarios, and estimate possible contracted demands. In this context, the study provides an analysis of the current contract of the organization and new options for demand contracts applied to tariff modalities, their respective time-of-use rates, and suggestions for demand contracts. The work successfully concluded, considering the situations analyzed in the simulations, which tariff modality is best for IFG in Valparaíso de Goiás, and it suggests a similar analysis for other campuses.
