MESOGEOS S.A. undertook, in consortium with AKTOR FM S.A. and GLOBITEL S.A., the “Maintenance and upgrade of the street lighting in the main roads of the Attica Region in order to save energy and reduce operating costs”. The relevant tender was conducted through an Open Process of the National System of Electronic Public Procurement (ESIDIS), by the Region of Attica, by the Directorate of Project Development Planning and the Directorate of Metropolitan Infrastructure Management. The value of the relevant contract, signed on April 20, 2021, amounts to € 37,000,000 and is financed by the Operational Program “Attiki 2014-2020” (NSRF 2014-2020). MES ENERGY S.A., as a subsidiary of MESOGEOS S.A. with extensive experience in energy saving applications such as LED lighting, has undertaken the Project Management and Asset Management of the project for 10 years.

The object of this contract is, first of all, the collection of data and the recording of the existing street lighting information, as well as the design and mapping of the specifications of the new street lighting system and the conduction of the necessary phototechnical study. This is followed by the supply and installation of 23,790 pieces of LED technology luminaires with a power of 150W to 1000W, which will replace the existing energy-intensive luminaires using Sodium lamps. It is worth mentioning that the existing luminaires require an annual light bulb replacement, whereas the new LED luminaires operate seamlessly for 10,000 hours, i.e. for over 20 years, thus reducing the maintenance requirements. The new luminaires are equipped with a wireless controller in order to be able to fully integrate into an IOT (internet Of Things) Management System. In addition, the supply, installation, configuration and commissioning of an IOT street lightning Management System will be realised, in order to achieve the management and control of the street lightning of the main roads of the Attica Region. The remote management system consists of the devices and procedures used by the end user to receive information related to the operation of the street lighting, as well as to give instructions concerning the configuration of its operating profile. For example, through the management system, the illumination level of the luminaires, their connection to motion sensors etc can be controlled. The three mentioned companies will also be responsible for the provision of operation and maintenance services for the lighting system for 10 years.

Through the above interventions, an annual saving of street lighting electricity cost of at least 65% is expected in the Attica Region, corresponding to 1.5 million € per year in favor of the citizens. An additional advantage that arises, apart from the energy saving and the improvement of the footprint of the Attica Region on the environment, is the improvement of lighting quality and visibility, which will improve road safety in the main streets of the Region. The advantages however, do not stop here, as the luminaires are fully controlled via a remote control system, which means that it is possible to receive data concerning their situation in real time, and therefore potential damage can be treated faster.

The upgrade of the lighting bodies began on December 6, 2021, on Poseidonos and Kifisias Avenues, and the better lighting quality is already evident. Similar works will follow in the most important avenues of Attica, such as Kifisou, Siggrou, Marathonos, Vouliagmenis, Alimou and Katechaki, as well as in the streets around the centre of Athens, such as Panepistimiou, Amalias, Vasilissis Sofias and Pireos.
