Energy Efficient Public Lighting in Vila Nova de Gaia, Portugal

Type: CaseStudy

Case Study (32 KB PDF)

Summary

ENERGAIA is supporting and promoting the reduction of public lighting energy consumption in Gaia municipality. In the preliminary study it was found that the best technical solution is the installation of flux control systems. Typically, flux control systems can save up 20% to 30% of energy, and also increase the life span of the lamps up to 30%.

In a first stage of the project it is planned the installation of 30 flux control equipments that will induce energy savings up to € 50.000,00 per year. The total investment is about € 250.000,00 that will lead to a payback of 5 years without considering savings in maintenance costs.

Results

In the first year (2003) it is expected 330 MWh savings and in the second year (2004), after the installation of the 30 flux control systems, 650 MWh savings. It is expected for the first year an economic savings of € 25.000,00 and for the second year (2004) a saving of nearly € 50.000,00. With a reduction of 650 MWh per year ENERGAIA will avoid the emission of 320 tonnes of CO2 per year.
