General information

  • The aim of the Danube InGrid (Danube Intelligent Grid) is to integrate more renewables to the distribution grid by the application of smart technologies and manage them in a smarter way along with keeping the security and high quality of supply for the electricity consumers in the CEE region.
  • Project Danube InGrid will adopt smart grid technologies both internally and on cross border level for the evolvement of modern energy infrastructure. It will efficiently integrate the behavior and actions of all market users connected to the electricity network, mainly consumers, prosumers and generators with the goal of integration of large amounts of electricity from renewable and/or distributed energy sources. Gaining and utilising experience in smart technologies in North Western Hungary and Western Slovakia, will be beneficial for electricity system users and distribution and transmission system operators.
  • The Danube InGrid project is on the 4th PCI list of the European Union. 
  • The Danube InGrid project is co-financed by the Connecting Europe Facility (CEF) of the European Union.
  • Project value: EUR 291 million
  • CEF co-financing: EUR 102 million
  • Implementation period: 2020 - 2025

Project benefits

  • The main benefit is to provide better and more economically efficient delivery of electricity supply for the strategic industrial areas and final consumers of both Western Slovakia and North Western Hungary.
  • The project will improve connection of more new renewable energy generators, quality of electricity supply, security of supply, network connectivity for all users and reduction of negative environmental impact.

Project goal

  • The main goal of the Danube InGrid project is to develop a smart grid in the CEE region in order to integrate more renewable generators to the distribution grid, with keeping high quality and security of supply for the energy consumers in the Western Slovakian and North Western Hungarian Region.
