The activity is focused on construction, renewal, and strengthening of border and cross-border high and medium voltage lines and modernization of a substation near Tvrdonice. Installation of smart elements (remote control, continuous measurement components) is also part of the activity.
Examples of specific activities:
The activity includes the construction of two substations, as well as upgrading transformer stations to "smart transformer stations" and installation of a significant number of smart elements for control and monitoring in distribution networks throughout the whole area covered by the project.
The activity aims to build a communication infrastructure between transformer stations, substations and the medium voltage network, including installation of smart elements, in order to enable effective data collection, communication among grid elements and for subsequent data sharing and remote management
The main output of this activity will be the establishment of a modern monitoring center and the implementation of several strategic IT solutions (both hardware and software) focused on data distribution.

Last month, we visited the infrastructure sites of two flagship projects supported by CEF Energy: ACON Smart Grids (Czechia-Slovakia) and Danube InGrid (Slovakia-Hungary). Both share the common goals of fostering the integration of the electricity market across borders; ensuring quality, safety and reliability of electricity supply; and enhancing the integration of decentralised Renewable Energy Sources (RES), new energy consumers, and e-mobility.
Both projects stand out for its work in modernising and improving the distribution grid''s efficiency at different locations in the Czech and Slovak territories, from the construction of overhead lines, underground cables, primary and secondary substations and border and cross-border overhead lines; to the installation of smart automatic and remote-controlled elements, new communication systems and integrated IT solutions. All these novelties result in an increase on the observability and controllability of the grid, allowing for a faster and more accurate reaction in case of failure, reducing disconnection times, and increasing the efficiency in the management of the grid.
In recent years, some of the regions covered by these two projects have been experiencing some societal changes, with more citizens moving from big cities to new residential areas. The new households are equipped with home renewable energy solutions (such as photovoltaic panels, electric heating, e-mobility) promoting greener behaviours, self-consumption and reducing both carbon footprints and energy costs. This shift, driven by the energy crisis and rising prices, has increased the demand for connecting new decentralised renewable electricity generation sources among households and enterprises, needing further development of the electrical distribution infrastructure to match this demand.
In this context, we were glad to attend the inauguration of the 110/22 kV Mierovo smart substation, which is part of the Danube InGrid project and built to cover the growing demand for integrating renewable energy sources to the grid, in particular in the Western Slovakia region.
Olivier Silla, Head of Department at CINEA, attended the event and said:
"Danube InGrid started four years ago as an innovative smart grid initiative between Slovakia and Hungary. By now, the modern-digital infrastructure implemented already represents a transformative step towards a more secure, flexible, and decarbonised electricity system in the two Member States, while bringing immediate benefits to local communities."
"The smart grids projects ACON and Danube InGrid show that by working together, Czechia, Slovakia and Hungary are not only improving their own energy security but also contributing to a stronger and safer European grid and energy network. It is a clear example on how European programmes such as Connecting Europe Facility are instrumental to build such infrastructure projects that are key in the clean energy transition," said Oliver Silla.
Both ACON Smart Grids and Danube InGrid have received the status of PCI (Project of Common Interest), what allows them to benefit from an accelerated permit granting process and improved regulatory treatment as well as to access CEF Energy funding.
ACON Smart Grids is benefiting from CEF Energy funding since 2018 with over EUR 91 million. The project is expected to be completed by December 2024. More information: https:// or LinkedIn
Danube InGrid is co-funded by CEF Energy since 2020 and has received EUR 102 million. The project should be completed by December 2025. More information: https://danubeingrid / or LinkedIn

Bratislava, 10 October 2023AGENDA
Panel 1. Developing smart grids projects for Energy Transition, followed by Q&A session
Scope: Considering the big volume of investments needed in the following years to modernize/ digitalize the grid and to increase efficiency and flexibility in order to ensure further integration of RES.
What are the challenges (regulatory, financial, technical, etc.) in place to develop smart grids projects at TSO and DSO levels?
What actions and by whom need to be taken to increase the number of smart grids projects with a better focus of RES integration and a reinforced cross-border cooperation among TSOs and DSOs?
Panel 2. Searching for synergies/means to enable smart grids projects, followed by Q&A session
Scope: In the first Smart Grids PCIs summit it was concluded that a better way of cooperating/communicating is needed among the stakeholders of the smart grids projects community. The format, e.g. the Summit, and scope should be discussed. Available technologies and replicability of solutions, best practices of implementation, financial instruments could be among those enablers for the smart grids projects. The panel is invited to contribute to these points by sharing the views and experiences.
