The project concerns the replacement of 92.28 % of all luminaires with accessories for energy-saving LED lighting, throughout the Skarżysko-Kamienna Municipality. The installation of energy-efficient lighting will reduce the energy intensity of the public sector and the demand for energy. Reducing energy consumption and CO2 emissions will improve air quality, thus protecting the environment and reducing municipal lighting costs. We'll increase the safety of residents, drivers. The city’s aesthetics will improve. The optimal option III of the implementation of the project based on the results of the energy audit was chosen. It assumes 92 units of control points outside the trafo stations, reducing the luminous flux, applying a fixed stream (CLO) throughout operation and upgrading: 4 706 sodium and mercury fixtures for LED luminaires, replacement: 3 371 booms with accessories, 132 pcs. Astronomical clocks. This investment is included in the Low-Emission Economy Plan and the Municipal Revitalisation Programme. Implementation of the project from 30.09.2019 to 30.12.2021 Design in accordance with the priority axis. 3 Efficient and Green Energy, Action 3.4 Low-carbon strategy, support for sustainable multimodal urban mobility ROP 2014-2020 projects for energy-efficient street lighting modernisation, for OSI and with the requirements of the competition rules. As a result of the project, 4706 units of lighting sources are planned to be modernised. Energy saving electric. 2240.77 MWh/year, estimated annual decrease in greenhouse gas emissions. 1806.06 tonnes of equivalence. CO2; in both indications, it accounts for 71 % of the savings. In addition, all mandatory horizontal output and result indicators and the amount of heat saved are included in the project.
