The urgent need for a transition to a zero-carbon economy by 2050 goes beyond the ability of the Distribution System to maximize the penetration of green energy. Existing targets set at national and European level make this need important (e.g. European Union target "A climate-neutral EU by 2050" and the National Energy and Climate Plan (NECP) for 2030 implementation). Already, the penetration of RES has increased significantly in recent years and its rate of increase is increasing. This penetration poses significant challenges to Distribution Networks as their development over time cannot support the maximization of this penetration. To make this possible, it is necessary to overhaul the distribution network and transform the way the system operates. It is clarified that a distribution system is defined as any system that includes electrical lines of medium and low voltage networks between automatic circuit breakers or medium voltage switches in transmission substations and/or primary substations and that are used for the distribution of electricity from generating units or other entry points up to the point of delivery to customers or other users, and any electrical equipment, devices and meters in relation to the distribution of electricity. The proposed project will allow the required real-time observability, control, and flexibility to be achieved so that networks can not only connect but integrate users, and green energy can flow seamlessly. In other words, the proposed project is expected to achieve the required supervision and control of the Distribution Network by achieving more efficient management and optimization of the Distribution System. In addition to the timely and effective integration of RES and emerging technologies into the system (storage, demand response, electricity traffic), the automation of the Distribution System is a key condition for improving the reliability and safety indicators of the network as well as ensuring the proper functioning of the Competitive Electricity Market (CERA Regulatory Decision 01/2015 on market design). The Automation and Modernisation of Medium and Low Voltage Networks (includes the majority of contracts declared for co-financing outside the contract entitled ‘Supply, delivery, installation, regulation and control of a new IT infrastructure for the National Distribution Control Centre’, andThe installation and operation of a modern SCADA/ADMS system and the simultaneous establishment and operation of the National Distribution Control Centre (EKED).With the implementation of the project, the following results/deliverables are expected:Modernisation of the Medium and Low Voltage Networks with the installation of the new switchgear and switchgear to be installed in an EAC Distribution System to collect information.Development of a complete infrastructure for the EKED, i.e. regional equipment and new IT infrastructure for the SCADA/ADMS system; Full operation of the EKED on a 24x7 basis (The operation of the EKED is not co-financed) Installation of the tools/applications for the management of the Distribution System, the proper functioning of the Competitive Platforms of the Electrical System, the Integration System and the ANEWC system with the integration of the rest of the Electrical System. It is clarified that end-users are defined as consumers, self-consumers (who produce for their own consumption), producers, energy storage facilities directly connected to the grid, etc., with each perhaps having different benefits. However, if we refer to the benefits in general, these are:Economic benefit: as the projects will be co-financed, most of the project costs (around 70%) will be covered by the JTF. Otherwise, these costs would be charged to customers' bills. Regarding the charging of project costs to network users, it is clarified that the implementation of upgrade and development projects related to EAC networks is a requirement of the Regulatory Decisions and relevant European legislations. If the projects are not co-financed, they are all counted together as "network charges" and charged to each user's account. If a project will be co-financed, then its cost is not included in the calculations of the relevant charges to users. Possibility to reduce the electricity costs of final customers: the possibility of timely and unrestricted installation of self-generation, the service of competitive electricity markets, the possibility to participate in flexibility programmes and services with their flexible sources (production, storage, recharging point for electric vehicles, but also other loads), enable final customers to eliminate their electricity costs.Provide better quality of service: final customers will enjoy a better quality of service: reduction of power cuts, reduction of downtime, improvement of power quality (overvoltages, undervoltages, etc.), better information and service in case of failure, and even reduction of grid connection time for appli
