Danube InGrid
Smart grid Project of
Common Interest of the European Union
Phase 2
🪧Under construction🪧
About the project
The project contributes to the implementation of the PCI 12.3 Danube InGrid, which aims to efficiently integrate the behavior and actions of all market users connected to the electricity networks in Hungary (HU) and Slovakia (SK), by developing modern infrastructure and adopting smart grid technologies to support the increasing demand of consumers, prosumers and distributed renewable energy sources.
The project aims to reinforce and digitalize the distribution grid in Slovakia by modernizing and upgrading the electrical infrastructure.
The project covers constructing new and upgrading existing medium-voltage (110/22 kV) substations and lines and installing new communication equipment and smart components in 22 kV lines and secondary substations, such as optical fibre, 4G systems, and monitoring and remote-control devices. The scope also includes the development of ICT-based control systems, such as a meteorological data exchange platform and an anti-drone monitoring system.
The overall objective of Danube InGrid 2nd Phase is to contribute to establishing a smart electricity grid integrating the behaviour of producers, consumers, and prosumers, achieving a stable, efficient, and sustainable power system, ready to meet the evolving challenges of the European Energy sector.
- The Danube InGrid 2nd phase is on the current PCI list of the European Union 12.3 Danube InGrid
- The Danube InGrid 2nd Phase is co-financed by the Connecting Europe Facility (CEF) of the European Union Action no. 12.3-SK-W-M-24-DanubeInGrid2ndPhase
- Danube InGrid 2nd Phase value: 65,76 million EUR
- Danube InGrid 2nd Phase CEF co-financing: 32,88 million EUR
- Danube InGrid 2nd Phase Implementation period: 2024 – 2028
Project promoters
Project activities
Danube InGrid: 2nd Phase includes
- Expansion of transformer capacities at six existing 110/22 kV substations: Gemerská Hôrka, Lemešany, Košice Juh, Kechnec, Rožňava, and Lubeník
- Construction of a new 110/22 kV substation in Lučivná
- New 2×110 kV underground cable line between Vajnory and Žabí Majer
- Approx. 100 km of 22 kV lines equipped with optical fibre
- Installation of approx. Sixty 22/0,4 kV smart secondary substations
- Expansion of meteorological Danube InGrid data platform
- Implementation of an anti UAS system security system
Project goal
The main goal is to develop a smart, resilient, and sustainable electricity distribution grid by:
- Increasing grid capacity to accommodate growing RES and e-mobility demand
- Improving cross-border energy flows and system flexibility
- Enhancing cybersecurity and operational efficiency through digital tools
- Enabling data-based network management
These efforts contribute to national and EU 2030 climate targets, reinforce cross-border electricity cooperation, and help the EU achieve its Green Deal objectives.
The project will enhance the security and quality of electricity supply in both the West and East of Slovakia, while also supporting the integration of renewable energy sources and e-mobility.
