Análise de viabilidade econômico-financeira de energia fotovoltaica em parques industriais

Abstract

Renewable energy alternatives stand out as sustainable possibilities for the reduction of greenhouse gas emissions, diversification of the energy matrix, efficiency in industrial energy management and stimulation of sustainability as a strategic environment. This work aims to analyze renewable energy alternatives that are economically and financially viable in industrial parks. Therefore, the study contributed to the advancement of knowledge in the use of renewable energy alternatives in industrial processes and administrative areas, and consequently, reduce the participation of non-renewable sources in the energy matrix. The study described the scenario for the participation of renewable energy alternatives in the industrial energy matrix, highlighting the potential for expansion of these energy sources to encourage the process of decentralization of energy supply between the increase in production and economic development. The identification of the availability and costs of each of the renewable energy alternatives mapped in the industrial parks was achieved with the construction of the data, the generation potential of each energy and the technical interest in the analysis of the production managers. The renewable energy alternative selected for economic feasibility analysis was the photovoltaic solar energy. The photovoltaic solar energy project proves to be feasible for the industrial parks analyzed, without considering values of specific investments in roofing infrastructure. In Location B and D, the necessary internal industrial area is sufficient for technical needs. In the plants in Location A and C, there is insufficient internal area of the plants to install the photovoltaic solar panels. However, the internal area available at companies is a determining factor as a variable for the success of a photovoltaic energy project. As for the economic engineering results for the Location A, the Net Present Value (NPV) is the lowest compared to other countries and the discounted payback was estimated at 117 months. In Location B, the investment for the installation of the photovoltaic solar project is the largest and the discounted payback was 133 months. In Location C, the NPV of the project is equivalent to R$ 13,887,681.42 and the discounted payback was 45 months. In Location D, the project's NPV is equivalent to R$ 5,941,318.69 and the discounted payback was 66 months. The results show sensitivity and scenario analyzes for the four industrial parks analyzed.
