Difusa˜o de sistemas de microgeração fotovoltaica em áreas rurais: estudo de caso

The expansion of distributed energy resources, in particular distributed micro and distributed minigeneration systems, are transforming the energy infrastructure of the electricity sector. In dealing with these changes, the models of predictive dissemination of technologies prove to be fundamental instruments support the decision-making process for improving the legal framework and public policies. In this sense, this article is addressed to the study of the diffusion of photovoltaic microgeneration systems in rural areas. The influences introduced by the new credit compensation system of Law No. 14,300 of january 2022 are evaluated, as well as tax incentives in the electricity tariff to the rural agricultural underclass. The study is based on data from a rural electrification cooperative in the state of Rio Grande do Sul. As a highlight point, the results obtained indicate that changes in credit clearing rules have importante impacts, especially in the rural farming underclass of the cooperative under study, with a 28.16 % reduction in the prospected adoption rate of photovoltaic microgeneration systems.
