Assessment of the Technological update of Public Lighting in Brazil

In recent years, Brazil has experienced several crises of electric energy, and in the face of this situation, there is a concern to apply consumer reduction actions based on the government program PROCEL. Public lighting, in particular, is one of the areas where energy efficiency actions can be applied through technological updating of lighting equipment. This study, therefore, aims to evaluate the impact of such a change in the electric sector. For that, pilot projects were considered with complete technological update of this park by LED technology. In this context, it was evaluated the reduction of the electric energy consumption and thus, presented a 10-year projection scenario in order to verify the benefits of the technological update in terms of electric energy consumption and reduction of the energy demand with some economic considerations and, consequently reduction in the energy bill of final consumers. In addition, this projection can be used to discuss the reduction of CO2 emissions, as upgrading of public lighting by LED technology will bring savings in consumption and energy production.
