Efficient and adaptive led public lighting integrated in évora smart grid

Lighting accounts for 19% of electricity consumption worldwide and 14% in the EU [1]. In Continental Portugal an estimate of 19% of global energy consumption is related with general lighting systems [2]. EDP Distribuição, shortly EDP D, (EDP Group), Portugal, as the main Distribution System Operator (DSO) in Continental Portugal, operates the Street Lighting Network (SLN) with a total energy consumption of 1,5 TWh, 3% of Portugal´s global energy consumption. As a DSO, fully committed to respond to the energy efficiency demands, to ensure a sustainability growth of Quality of Service (QoS) and to answer the needs and expectation of clients, EDP D has been systematically upgrading the network with new efficiency technology and testing new emerging technical solutions to mitigate risk, namely, the impact in maintenance, management and operational process.
