Estudo de caso: análise de viabilidade econômica da implantação de luminárias LEDs em trechos do sistema de iluminação pública da cidade de Forquilha-CE

Abstract

This work presents an analysis of the economical feasibility of replacing conventional luminaires in some of the main public thoroughfares in the city of Forquilha by LED luminaires. Faced with the increasing demand for electricity and more efficient lighting technologies, it is important to evaluate the feasibility of adopting new technologies in public lighting, seeking to reduce costs and reduce system demand. It is presented a methodology capable of estimating the energy consumption by surveying the consumption data of the public lighting system in the municipality of Forquilha - Ce, in comparison to the consumption of the efficiency proposal, and the acceptance of the new technology with the help of TIR and payback economic tools, study the feasibility of project implementation. The results show that with the change of luminaires with conventional lamps by LED luminaires, the energy demand in the analyzed segments had a drop of 21.45 kW and a reduction in the monthly cost with energy of 48.58%, that is, almost half of the energy currently consumed is saved. Taking into account the economical value, disregarding the labor and maintenance costs of the existing luminaires, economic viability simulations were performed with the TIR and payback tools and showed economic viability of the project.
