Análise de viabilidade econômica da implementação de luminárias led na iluminação pública: estudo de caso no município de Massapê-CE

Abstract

This study aims to develop a feasibility study for the introduction of LED luminaires, replacing metallic vapor luminaires in part of the public lighting system of the city-state of Masape Che. In this sense, this work has the general objective of identifying the main factors that justify the replacement of current metal halide lamps by LED lamps. Therefore, it is necessary to conceptualize the equipment used in public lighting to understand its operation, analyze the advantages of LEDs in relation to metallic vapor lamps and analyze, through simulations, the economic viability of replacing it with IRR (Internal Rate of Return ). tools and refund. Based on exploratory research, based on primary and secondary sources and with a qualitative and quantitative approach, the study shows that the replacement of light fixtures will mean a reduction of 56.47% in the monthly demand for electricity in the streets, squares and avenues analyzed. considering the amount that will be saved and including the costs of labor, thanks to the economic feasibility simulations with the TIR and recovery tools,it will be possible to analyze whether the project will be economically viable or not.
