Análise migratória de uma universidade do Oeste do Paraná ao ambiente de contratação livre de energia elétrica

Abstract

The Free Contracting Environment (ACL) represents 39% of total electricity consumption in Brazil, with a growth of 20% in the last 12 months. Currently, there are 69 thousand Consumer Units (CUs) eligible to join the ACL, and the expectation is that, from 2024, with the opening of the market for the high voltage group, another 106 thousand UCs will become eligible. The advantages of participating in the ACL include the possibility of choosing the energy source used, cost optimization and the elimination of charges and subsidies present in the regulated environment. The difference in prices and discounts obtained by free consumers arises from the freedom of negotiation and the absence of charges associated with the regulated environment, providing greater competitiveness and savings in electricity consumption. With the significant number of consumers still in the regulated environment, the tendency is to have more and more free consumers, making it a market in great expansion and requiring professionals to analyze and make migration reports available to those interested and who can migrate according to the current legislation. This work aims to analyze the economic viability of migrating a University of Western Paraná within the Regulated Contracting Environment, to its classification as a special consumer in the Free Contracting Environment. For this work, historical data on consumption and demand from the University were used, in addition to data on taxes and tariffs from the National Electric Energy Agency (ANEEL), specific to Companhia Paranaense de Energia (COPEL). Data was also obtained from a commercial proposal from an energy supplier to simulate the billing values in the ACL according to ANEEL guidelines in 2023. With an initial investment of approximately 40 thousand reais, the simulations were conducted in four hypothetical scenarios over the course of 60 months, allocated to joining the CCEE and adapting the Billing Measurement System (SMF). The scenarios include: Scenario 1 - TE's ANEEL adjustment, Scenario 2 - TUSD's ANEEL adjustment, Scenario 3 - ACL price adjustment, and Scenario 4 - expected adjustment, including sub-scenarios. Analysis of variations in the economy over 5 years. In Scenario 3, the sub-scenario without variations and price adjustment was selected reflecting stability in current prices, the migration savings over 5 years are between 24.19% and 31.30% in relation to the regulated environment. When comparing the results obtained in the scenarios, the critical values of important adjustments to maintain the advantage of the ACL were highlighted. The University's migration to the ACL revealed economic benefits, highlighting the elimination of subsidies and charges present in the regulated environment, in addition to discounts associated with the use of renewable energy sources. The strategy of energy consumption from renewable sources, with 50% encouraged, demonstrated a reduction in electricity expenses over 5 years of migration. In the sub-scenario with price stability of Scenario 3, savings vary between R$691,909.60 and R$988,074.71.
