ANALYSIS OF THE ECONOMIC VIABILITY OF THE INSTALLATION OF A PHOTOVOLTAIC SYSTEM AT JORGE DE ABREU REGIONAL HOSPITAL IN SINOP-MT

Abstract

Brazilian consumers have the possibilit y to produce their own energy using renewable sources or qualified cogenerat ion and even provide the surplus for the distribut ion net work of their localit y, as determined by Normat ive Resolut ion no. 482/2012 issued by the Nat ional Electric Energy Agency (ANEEL). In view of this, the use of photovoltaic systems for electricit y generat ion has grown surprisingly reaching the mark of 8 gigawatts of installed power on Brazilian soil in the year 2021 [1]. In Brazil, public agencies represent 0.1% with 4.7MW installed [1], and 0.38% in the state of Mato Grosso [14]. Thus, aiming at the rise of electricit y generat ion in public buildings due to the possibilit y of reducing the electric bill costs, the present work deals with the dimensioning, budget quotat ion and economic feasibilit y analysis regarding the installat ion of a grid-connected photovoltaic power generat ion system to meet the energy demands of Jorge de Abreu Regional Hospital in the cit y of Sinop, Mato Grosso state, Brazil. After carrying out the necessary research based on the techniques present in the economic sciences, as Minimum Attract iveness Rate (MRA), Net Present Value (NPV), Internal Rate of Ret urn (IRR) and calculat ion of Payback, the present work considered a grid-connected solar energy generat ion system of 585 kW to supply the hospital’s average monthly consumpt ion of 93.829 kWh/month. The investment analysis showed that the project for the implementat ion of the photovoltaic system will have its NPV viable as of the 4th year of installat ion and the Payback (ret urn on investment), observing the monetary correct ions, of approximately four years and five months, thus configuring the system as economic financially.
