Electrical Engineer from the Federal University of Rio Grande do Sul - UFRGS. He has a specialization in Mechanical Engineering from UFRGS and in Economics, Regulation and Competition in Public Services from the University of Barcelona. He has experience as a teacher in the field of electricity, as a planner for the expansion, grants and regulation of electricity transmission systems. Since January 2007 he has been a Specialist in Regulation of Public Energy Services, a career server at ANEEL - Agência Nacional de Energia Eletrica. Actually he is a Studying of an Academic Master's Degree in Renewable Energies, since 2019, at the Federal University of Paraíba - UFPB.
Brazil is currently undergoing changes to regulations on distributed generation (DG), specifically for solar energy micro-generation. The changes proposed by the Brazilian Regulatory Agency suggest that only the cost of energy be compensated to investors. The service costs and other charges related to energy tariffs must be divided among consumers. Investors with existing installations and class entities have contested these proposals, calling them “sun-fees”. To date, no scientific papers have been published discussing these changes. The new regulations propose an end to cross subsidies, where all consumers (even those who do not have DG) pay for the transmission and distribution systems. This study compares the economic feasibility of micro-generation before and after implementing the new standards proposed by the regulatory agency. We used data on average electrical energy demand, energy price, and solar radiation in different regions. The national averages were used as a base comparison with other scenarios. The results show that projects are viable for all analyzed scenarios, however, after implementing the proposed changes, the discounted payback time is extended. This, however, does not make projects unfeasible.
