Projeto Técnico e Viabilidade Econômica de Usina Fotovoltaica em Indústria Metalúrgica

Abstract

This work proposes a technical project and economic feasibility for a photovoltaic generation system with distributed generation to be installed in a metallurgical industry in the city of Goiânia. Distributed generation is seen as an alternative to expand the energy potential with low investment in infrastructure. The proposed model takes into account the specific needs of consumption and physical characteristics of the installation location, as well as the requirements for approval from the power utility company. The methodology employed in this study consisted of an analysis of the economic feasibility related to the implementation of a photovoltaic plant in a metallurgical industry. Initially, the load survey was conducted, using the company's consumption history as a basis, duly recorded with the electric power utility. Subsequently, the PVSyst software was used to size the photovoltaic system. In this context, detailed calculations were performed to determine the necessary power, a careful selection of equipment, and the quantity required to ensure the desired energy efficiency. The next step involved an analysis of economic feasibility, including the evaluation of costs associated with the system implementation, cash flow projection over time, and the estimation of savings to be achieved. Additionally, the payback period for the investment was calculated. The analysis culminated in the preparation of a statement that encompasses the cost- benefit relationship of the project at hand. The conclusion reached is that photovoltaic systems, even considering the new tariff rules, constitute highly advantageous solutions for energy savings and the mitigation of challenges arising

4 from the growing energy demand. These systems not only offer attractive profitability but also notable longevity, reinforcing their position as highly recommended alternatives for companies, such as the metallurgical industry under consideration, seeking to optimize their energy resources sustainably and economically.
