Public street lighting (PSL) with its multiple roles, is nowadays a central concern in smart and sustainable cities, urban and rural area, and street planning. However, PSL consumes a considerable amount of energy. Energy efficiency and conservation (EE) as a component of demand side management (DSM) concept have emerged for electrical energy consumption management. This paper focuses in this context, addresses and discusses the DSM activities in the street lighting sector (SLS). Firstly, three scenarios of street lighting systems are simulated with the already used conventional lamp, i.e. High Pressure Sodium (HPS), namely solar islanded street lighting, solar/grid connected, and solar/storage/grid connected street lighting system. Secondly, the three scenarios are simulated using Light Emitting Diodes LED technology, which is used as a means of load management and energy efficiency measures. To determine the optimal configuration in each scenario and to find the best between these three scenarios, the technical-economic feasibility analysis based on the net present value (NPV) and cost of energy (CoE) is carried out by using HOMER software. Based on the results obtained, the public street lighting system that uses LED lamp in all scenarios has the lowest CoE, NPV, and consequently electricity bill cost, and their use reduces the energy consumption by 30%. The second scenario is the most economical one with NPV($), CoE($/kWh), RF(%) and annual electricity bill cost ($) of (2033-1053), (0.091-0.19), (129,948-82,46) and (78.3-47.6), when using HPS and LED technologies.
