Análise do impacto econômico das novas propostas de regulamentação da ANEEL para micro e minigeração distribuída. Estudo na Universidade Tecnológica Federal do Paraná (UTFPR), campus Pato Branco - PB

Abstract

In 2018, the National Agency of Electric Energy (ANEEL) initiated a new review of Normative Resolution (REN) 482/2012, which regulates the Micro and Mini Distributed Generation (MMGD) market and the Compensation System of Electric Energy (SCEE) in the Brazil. As a result of the process, proposals were made to change the SCEE to Remote Distributed Generation (GD) and Local Distributed Generation, which were based on not compensating any component of the electricity tariff.In the proposal for GD local, the Wire B component of the Distribution System Use Tariff (TUSD), which represents 28% of the net tariff in the Brazilian average, is no longer compensated. Thus, the valuation of generation changes, making it interesting and necessary a study to assess the economic impact this can have on new MMGD projects. With electricity consumption and generation data from the Federal University of Technology - Parana (UTFPR), campus Pato Branco (PB), which has a local photovoltaic mini-generation system, an analysis of the economic impact of the possible change is carried out, evaluating some economic viability indicators, such as the Net Present Value (VPL), the Internal Rate of Return (TIR) and the discounted payback, in the current rule and in the new proposed rule. As a result, it was found that the increase in discounted payback due to the new rule proposed by ANEEL, even in the most unfavorable scenario of simultaneity between consumption and generation, is not significant to change the feasibility and attractiveness of the photovoltaic project at UTFPR, campus PB. Also, the simultaneity between consumption and generation was not a preponderant factor for the analysis. Thus, new GD local projects continue to be viable and attractive for the new rule proposed by ANEEL.
