Estudo da viabilidade econômica para a instalação de sistemas fotovoltaicos nos campi do IFG Itumbiara e Uruaçu

Abstract

This paper presents an economic feasibility study for the installation of photovoltaic systems connected to the grid on the campuses of the IFG in the municipalities of Itumbiara and Uruaçu, aiming to make up for all the energy demand of these institutions. The study was carried out using data on energy consumption, referring to tariffs for the year 2016, and all the analysis regarding the electric energy compensation system was based on normative resolutions 482/2012 and 687/2015 of ANEEL. Featuring the electricity monthly consumption were carried out the way of calculations to obtain the scaling of minimum power for compensation of all consumption, given that energy bills are one of the biggest expenses in most public institutions of higher education . The results of the analyzes indicated an annual energy savings for the Itumbiara campus of R $ 168,474.41, equivalent to a reduction of 93.51% in the amount billed. For the Uruaçu campus, the annual savings reached R $ 202,140.13, reaching a reduction of 99.94% in the energy bill. The economic valuation was performed through discounted Payback and Net Present Value (NPV) methods, which signaled the economic viability of the project with a financial return of the project in about 11 years for both campuses.
