Análise de caso para uso de tarifa convencional, tarifa branca e instalação de sistema fotovoltaíco on-grid: cálculo de economia e payback

Abstract

The high demand for electricity is a factor present in the current scenario worldwide and the increase in energy costs lead to the search for other ways of energy generation and even the reduction of consumption by consumer units. Based on this, ANEEL (National Agency for Electrical Energy) created the tariff modality called White Tariff, which aims at lower energy costs at times when total consumption by the system is lower and more expensive costs at times that are higher. However, since there are numerous options such as distributed generation and the Free Energy Market, it is valid to carry out analyzes to understand if the profile of that consumer unit fits with the White Tariff or if it would be more advantageous to create an energy generating unit, maintaining in the conventional tariff profile. The present work aims to carry out a case study of a security company located in Curitiba and evaluate the costs by making a comparison keeping the consumer unit with the conventional tariff profile, using the White Tariff and implementing a photovoltaic system to meet the demand of energy of this company, in addition to performing a calculation of savings and payback considering if this company is installed in other cities in each Brazilian region: Manaus, Fortaleza, Cuiabá, Rio de Janeiro and Curitiba.
