Telemanagement of public lighting systems - EcoEnlight

Almada, Portugal

The EcoEnLight project was implemented by the municipality of Almada between 2011 and 2013. This project was focused on improving the energy efficiency of Almada’s public lighting system, which accounts for more than 60% of the municipality’s energy consumption. During the EcoEnLight project, a smart telemanagement system for Almada’s public lighting system was procured and implemented. This tele-management system allows to remotely manage public lighting intensity in Almada by adjusting the luminous flux of all the lights throughout the day. This way, a more efficient and tailored energy consumption coming from the public lighting system can be ensured, which fully takes into account the needs of the citizens who use Almada’s roads during day and night. Thanks to the EcoEnLight project, the city has been able to reduce the energy needs for public lighting by roughly 40%. This represents a reduction of nearly 0.6 GWh and 300 tons of CO2eq. The savings estimations, which include maintenance and electricity cost savings, pointed to an average of €80,000/year. More than €464,000 were invested in the EcoEnLight project in total. Roughly 1500 light points were refurbished which means roughly 5% of all the public lighting in Almada. The success of the
EcoEnlight approach led to the development of the EcoEnlight II project which is currently under preparation and on the pipeline for financing of 3335 light points (this time adding to the tele-management system the replacement of lamps to LED lighting). An overall investment of roughly €1,500,000 for annual saving of €170,000 and a payback period of 8 years. At the end of this intervention more than 15% of the public lighting in Almada will be highly efficient.
