As part of this project, the necessary construction and assembly works will be carried out to improve the energy efficiency of external lighting. A circular and a hive. Katowice/Kościuszki on national road 81 in Żory. The scope of the investment depends on the characteristics planned for modernisation of the lighting infrastructure and includes, among others, replacement of luminaires with energy-efficient LED type, installation of control and street lighting management systems and partly replacement of columns and booms (due to the lack of possibility of installing luminaires on existing poles and masts). As a result of the project, the energy efficiency of external lighting will be improved and thus the costs of maintaining municipal infrastructure (by saving electricity costs) and greenhouse gas emissions will fall. The potential additional effect of the project is the increase in road safety and the safety of residents.
