Barreiras e potencialidades à difusão de geração fotovoltaica, conectada à rede de distribuição, no estado do Tocantins

Abstract

In countries like Germany, Japan, the United States and China, the photovoltaic power generation occupies a prominent place among their main electric energy generating source. In Brazil, the photovoltaic power generation is being timidly introduced. However, it does not stand out as an electric power source in its energetic matrix. There are evidences that its development inertia is related to economic, regulatory, institutional and market barriers. In an attempt to find the factors that prevent its dissemination in the State of Tocantins, this research seeks to engender knowledge about the main hindrances to the use of that source, through a case study, with the application of the systemic thinking method. It aims to meet the increasing demand of electric power and making it possible a popularization of the renewable sources. In the first phase, a better understanding of the studied topic was carried out. Thereupon, some interviews with specialists were performed. They provided the comprehension of the current situation of the photovoltaic systems diffusion in the state, thus confirming the existence of obstacles and creating a basis for the preparation of systemic mini structures that, subsequently, were consolidated into a single structure, presenting the data encountered. The obtained results demonstrated the problems confronted by the distributed photovoltaic generation in the state, reaffirming the existence of economic, institutional and market barriers among others, what obstruct the spreading of that source. Actions to eliminate or minimize those obstacles were proposed.
