Dimensionamnto e análise de viabilidade econômica de uma fazenda solar de 3,12MWp diante dos novos cenários de cobrança proposto pela ANEEL

Abstract

This work presents an economic viability analysis of building a kind of solar farm photovoltaic plant with shared generation and remote self-consumption, as ANEEL norm 687/2015 defines it. By 2019, it was expected a regulation change, which created a large instability for the future of distributed generation in Brazil. The analysis describes the 2015 and 2019 ANEEL concepts and evaluates the impact that each alternative has on project viability indexes. The proposed solar farm will be established in Araxá/MG, so that the local climatic aspects are regarded. In addition, the equipment set is considered, namely the energy generation source of 3.12MWp capture power and 2.5MVA connection power. Considering the photovoltaic generation system’s data of irradiation, temperature, and losses, the estimated generation is calculated making use of the software PVsyst. Finally, bearing these generation data and relating them to both the overall investment costs, like those of acquiring all the equipment needed, operating costs (including maintenance), taxes, and the proposed discount in the retail price, it is shown the outcome of the investment indexes, net present value, internal rate of return, and investment payback. Moreover, these results compare the old and new ANEEL norms to see the better economic viability.
