Description
The project proposal covers part of the street lighting of Pazardzhik connected to a total of nine power points located on the following main streets - G. Benkovski Blvd., Gen. Gurko Street, Plovdivska Str., Kocho Chestimenski Str., Tsar Osvoboditel Str., Bulgaria Blvd., Stefan Stambolov Str. The project proposal includes the implementation of Energy Saving Measures (ESM) relating to: replacement of existing LVL and CFL lighting with LED lighting; introduction of Automation and Control System and Monitoring of electricity consumption from external lighting; and the introduction of a renewable energy facility for outdoor lighting in the city. The introduction of a Street Lighting Automation and Control System (ACS) and Consumption Monitoring (CM) will directly affect the energy savings of the street lighting system, thus further optimizing the cost of lighting maintenance and will create the opportunity to achieve additional savings in electricity. The introduction of RES to power the luminaires will provide an opportunity to: reduce conventional power consumption and reduce greenhouse gas emissions generated. The overall objective of the project proposal is to improve the lighting environment, reduce electricity consumption and reduce operating costs. The specific objectives of the project proposal are:
1. Improving the energy efficiency of street lighting and reducing electricity consumption from the street lighting system.
2. Maximize the time to accumulate energy losses, but without increasing the cost of maintaining network traffic.
3. Reduction of direct costs of the Municipality for street lighting with high quality of lighting provided.
4. Ensuring the safe movement of motor vehicles, increasing the safety of pedestrians during the dark hours of the day and creating a comfortable night atmosphere.
Summary of project results
The main part of the lighting fixtures in the street lighting system of Pazardzhik municipality before the start of the project activities includes old high-pressure sodium lamps (HPS) with an installed power of 84W, having a weak luminous flux with high energy consumption. Before the implementation of the project, the lighting operates throughout the dark part of the day, without the possibility of dimming or turning off some of the lighting fixtures. Information about their condition is obtained by subjective assessment by the municipality staff through on-site inspections. The control gear in the lighting fixtures is electromagnetic, which leads to large losses of electricity in the system. The implementation of the project aims to carry out an energy-efficient reconstruction of street lighting, covering part of the territory of the city of Pazardzhik, by replacing the existing high-pressure sodium lamps (HPS) and compact fluorescent lamps (CFLs) with LED luminaires, introducing an Automation and Control System and monitoring of the consumption of electrical energy from outdoor lighting, as well as introducing a facility for producing energy from renewable sources for the needs of outdoor lighting in the city.
As a result of the successful completion of the project, old HPS and CFL luminaires have been replaced with new high-efficiency LED luminaires, an Automation and Control System and Monitoring of the consumption of electrical energy from outdoor lighting have been introduced, as well as a facility for producing energy from renewable sources for the needs of outdoor lighting in the city.
Reduction of electricity consumption for lighting, respectively of the municipality''s costs for its purchase, as a result of the technological renovation and modernization of the outdoor artificial lighting systems. Ensuring the standards for lighting of high, medium and low-traffic roads in the city, including in front of administrative buildings, schools and kindergartens, health facilities, hotels, etc. The introduced Street Lighting Automation and Management System (SAM) and Consumption Monitoring (CM) has a direct positive impact on electricity savings, by further optimizing lighting maintenance costs and creating the opportunity to achieve additional electricity savings. By introducing a facility for producing energy from renewable sources to power the lighting fixtures, an opportunity has been provided to reduce the consumption of conventional electricity supply and to reduce the generated greenhouse gas emissions.
