Estudo de viabilidade de migração para o mercado livre de energia: caso UTFPR campus Cornélio Procópio

Abstract

The continuous increase in electricity consumption in Brazil, combined with the country's dependence on hydroelectric sources and the tariff fluctuations caused by water crises, has led large consumers to seek more economical and sustainable alternatives for energy supply. This scenario makes it essential to analyze new contracting models that can offer greater stability and efficiency in energy use, especially for institutions with high consumption levels. The Brazilian electricity market has been undergoing a transformation driven by the gradual opening of the Free Energy Market (ACL). This model allows consumers to choose their suppliers and directly negotiate prices and conditions, increasing competitiveness and encouraging the use of renewable sources. In 2025, the ACL surpassed 75,000 consumer units, demonstrating significant growth and a rising interest among large consumers in joining this model. This study aims to analyze the economic feasibility of migrating the UTFPR - Cornélio Procópio Campus from the Regulated Contracting Environment (ACR) to the Free Contracting Environment (ACL). To achieve this, an automated spreadsheet was developed to compare the electricity bills of both environments, projecting medium-term savings while considering the necessary adaptation and contracting costs associated with the migration. The results indicate that the migration to the ACL presents potential for significant cost reduction and greater predictability in the institution's energy consumption. In addition to economic benefits, joining the free market promotes the acquisition of energy from incentivized renewable sources, contributing to sustainability goals and reducing environmental impacts, thus reinforcing the institution's commitment to energy efficiency and the responsible use of resources.
