The City of Belgrade has launched tendering for the provision of services to conduct a feasibility study with a preliminary project for the implementation of a public lighting remote control system in order to improve energy efficiency.
The application deadline is May 20, and the study is to include:
– A review of the existing public lighting system.
– Verification of the current energy situation – calculation of annual consumption.
– Drafting of the proposal for modernization by introducing a remote control system.
– Calculation of the costs necessary for the modernization of the public lighting system.
– Calculation of the expected energy savings and maintenance costs reduction based on the review of the current state of the public lighting system and system simulation with new modernized equipment.
Public lighting consumes 350 GWh per year, which is 2.3% of business and 1.1% of total electricity consumption in Serbia
In the tendering documentation, the City of Belgrade said that energy efficiency in all sectors is one of the main priorities. Electricity consumption for public lighting stands at 350 GWh per year, which is 2.3% of business electricity consumption and 1.1% of total electricity consumption in Serbia.
The electricity bill and maintenance costs of public lighting can be reduced significantly through the introduction of a monitoring and management system, the City said.
Examples of good practice have shown that it is possible to achieve 20% to 40% electricity savings by introducing public lighting management equipment and new light sources.
Therefore, the introduction of a new control system for the monitoring and management of public lighting presents itself as a significant concept of saving energy, as well as ensuring a high-reliability public lighting system, the tendering documentation reads.
The public lighting control system is a solution that allows remote control, for example switching on and off groups or individual lamps (as requested by the customer), remote diagnostics, and the regulation of their luminous flux (dimming).
The system should allow two-way communication – the ability to send a command, but also to receive information on the current status of the lamp, as well as confirmation that the command is executed. In this way, energy could be saved in late night hours when traffic is not heavy or whenever there is a need.
Another great advantage of the control system is the reduction of maintenance costs, according to the tendering documentation.
