Description
The overall objective of this project proposal is to increase energy efficiency and improve living conditions in the Municipality of Vratsa by technological upgrading and modernization of an external artificial lighting system. The main activities are the replacement of 927 pcs. luminaires, installation of 380 pcs. solar lamps for sidewalks, supply and installation of new resources for monitoring energy consumption and equipment to the management system as well as project management, exchange of experience and good practices, publicity and visualization, etc. Expected results are improved EE in the city, reduced CO2 emissions, energy and money savings, contemporary and modern street lighting, which will have extended life and reduced maintenance costs. The safety of people and motor vehicles will be increased. The overall objective of this project proposal is to increase energy efficiency and improve living conditions in the Municipality of Vratsa by technological upgrading and modernization of an external artificial lighting system. Specific objectives of the project proposal are: • Energy savings and reduction of CO2 emissions through modernization of street lighting in Vratsa Municipality - with saved 693,474 MWh/y energy and 818.30 t/y CO2 emissions will contribute to the achievement of Bulgaria''s and the EU''s environmental and climate protection goals. • Reduction of light pollution and electricity losses. • Increasing the production of energy from renewable sources by 10.31% by installing 380 pcs. solar lamps for sidewalks. • Improving the quality of street lighting in the city of Vratsa by replacing old cushioned street lamps and inefficient CFLs with new LED lighters. • Creating conditions for safety and security of the movement of citizens and motor vehicles during the dark part of the day and last but not least creating a comfortable and aesthetic night atmosphere in the urban environment.
Summary of project results
The problems that are intended to be solved with the implementation of the project are: to increase the energy efficiency of street lighting in the territory of the city; to reduce greenhouse gas emissions; to reduce the municipality''s electricity costs; to improve the quality of street lighting and increase the percentage of illumination; to improve road safety for drivers and pedestrians at night; to increase the production of energy from renewable sources; to increase the expert capacity of the municipality''s employees in the field of renewable energy, energy efficiency and energy management. In addition to reducing direct electricity costs after the implementation of the project activities of the measures, financial savings are also expected from reducing the annual costs of operation and maintenance of the outdoor artificial lighting system. These savings are due to the elimination of the need to replace lamps and the significantly less frequent replacement of lighting fixtures, including labor and material costs.
Old lighting fixtures replaced, with the total length of streets covered by the street lighting project being 12.958 km. Solar lamps installed on existing poles. Street lighting control system introduced by installing an additional control module in each lamp. Reduced lighting power during off-peak hours between 0 and 5 a.m. Current information signals damage or theft of electricity. The option to choose automatic or manual control is provided. New means of monitoring electricity consumption delivered and installed. The option to monitor consumption in real time and permanently record data through advanced cloud technology is provided.
Modernized and reconstructed street lighting. Replaced 927 old depreciated street lighting fixtures, operating with NLVN with new LED lighting fixtures with power from 40 to 100W, min. 120-140lm/W, light distribution - with 0.0% upward luminous flux emission. Installed 380 solar lamps for sidewalk spaces. Introduced a street lighting control system by installing an additional control module in each lamp. Delivered and installed new means for monitoring electricity consumption. Implemented measures for the effectiveness of the energy efficiency investment related to the amount of saved greenhouse gas emissions - 1351.60 BGN/tCO2.
Summary of bilateral results
Improved bilateral cooperation with interested stakeholders in the field of energy efficiency to present good practices and future development of the city and the municipality in this regard.
