Estudo da viabilidade de migração para o mercado livre de energia: caso do IFPE campus Recife

Abstract

Bearing in mind the importance of the previous study of the economic viability related to the change in the energy contracting environment, the present work sought to carry out a case study regarding the migration from the Regulated Contracting Environment (ACR) to the Free Contracting Environment (ACL), considering the Federal Institute of Pernambuco (IFPE) on the Recife campus as a consumer, with the aim of analyzing whether said change is economically viable. The methodology addressed was based on the breakeven point method, whose purpose is to obtain the cost of energy in the ACL in which the expenses are equivalent to the expenses in the ACR. In view of this, data generation was carried out considering the contracting of incentivized energy with discounts of 50% and 100% in the Tariff for the Use of the Distribution System (TUSD), obtaining an average breakeven point value of R$502,71/MWh for the 50% discount case, and R$695,53/MWh for the 100% discount case. These values, when compared to market values, were considerably favorable for joining the ACL, since the highest value verified in the ACL was R$190,00/MWh for the case of a 50% discount, and R$326,01/MWh for the 100% discount case. In addition, having the calculations related to the annual savings, considering all the expenses related to the migration of environment, it was found that migrating to the ACL would bring the consumer total savings, over five years, of R$94.378,17 in the case of a 100% discount, while in the case of a 50% discount, staying in the ACR was presented as more advantageous, with a total saving of R$18.283,29 over the five years. Thus, it is concluded that, for the considered consumer, the most advantageous option is the adoption of 100% incentivized energy
