The luminaires must have zero light upward. The luminaires will have electronic ballast and a efficiency of 95%. 2. Installation of solar lamps for sidewalk lighting: The possibility of using renewable energy sources to supply street lighting on sidewalks has been evaluated. It is possible to use a solar lamp with a built-in battery with a power of 20W, without the need for additional power supply. The measure will save 12% of total energy consumption after ECM. 150pcs will be installed. solar lamps placed on the existing pillars along the streets: Marin Boev, Georgi Dimitrov and Rayko Daskalov. 3. Introduction of a street lighting control system, resulting in a reduction of the lighting power in hours with reduced movement between 0 and 5 hours. When the street lamp is switched on, it will start operating at 100% of its power, at 00:00 it will decrease to 50% and at 05:00 it will be switched on again at 100%. This will lead to normal lighting with significant energy savings The envisaged project is 683 990.35 BGN for a period of 18 months. The activities are implemented in cooperation with the Norwegian partner Executive Decision Support AS.
