Análise de viabilidade da migração tarifária de consumidores industriais para tarifa branca em conjunto com geração distribuída e banco de baterias

Abstract

Over the years, electric power, an essential and indispensable input in society's daily life, has become increasingly costly for the end consumer, especially for the industry, considering that the energy bill ranks among the top three costs for businesses. Reducing this cost is a fundamental action as it leads to savings in production expenses, thus generating greater competitiveness in the market. In order to achieve this reduction, measures need to be adopted. Changing tariff modality and distributed generation combined with a storage system are some of the current options. Based on this, this project conducted an analysis applied to three industrial consumers in tariff group B, considering three distinct scenarios in order to obtain the costs of electric power in each of them. The scenarios considered included the use of white tariff, distributed generation, and battery storage systems, and at the end, the energy costs in each scenario were compared to find the one with the lowest cost. The conclusion drawn from these results was that changing from a conventional tariff to a white tariff results in reductions in the energy cost. However, the scenario that utilizes distributed generation to fully supply the industrial consumption presented the lowest energy cost. Regarding systems that use lithium batteries to store the energy generated by the photovoltaic system, they showed lower energy costs for application during the intermediate and peak periods of the white tariff compared to the regular tariff itself. The systems that use lead-acid batteries were not viable according to the project's purpose. [resumo fornecido pelo autor]
