ANÁLISE DE VIABILIDADE ECONÔMICA PARA A IMPLANTAÇÃO DE SISTEMAS DE GERAÇÃO DE ENERGIA SOLAR FOTOVOLTAICA E EÓLICA PARA O ABASTECIMENTO DO MUNICÍPIO DE JANAÚBA - MG E REGIÃO

Abstract

Over the years, the environmental factor has become paramount, and as a result, there has been an increased focus on the implementation of sources of electrical power generation from renewable and clean sources of energy. In Brazil, the majority of the energy matrix is still composed of non-renewable sources of energy, but this is changing increasingly, mainly due to government incentives through credit programs. Specifically, in Minas Gerais, the electrical matrix is still heavily dependent on hydroelectric power, but this is also being changed due to the large energy potentials from other sources such as wind and sun, which are considered renewable sources of energy. The Janaúba region, located in the northern of Minas Gerais, as demonstrated in various surveys, presents a large wind and solar energy potential for power generation, however, there is still no relevant information on the economic viability of the implementation of these two sources. In this sense, this work aimed to analyze this problem, bringing relevant information through simulations made in the System Advisor Model (SAM) software, which presents various feasibility analysis mechanisms, including the Levelized Cost of Energy (LCOE), which provides data such as energy cost per kWh, bringing the possibility of economic comparison between the implementation of both sources, with the aim of supplying the city of Janaúba and region. From the simulations made in SAM, it was possible to conclude that there is economic viability for the implementation of both sources, and in comparison to one system to another, a difference of 1.66% was found, favoring the wind power generation system in terms of LCOE, showing to be more viable, due to having a higher productive capacity factor in the considered 20-year interval.
