Elia and Energinet’s collaboration is advanced following preliminary study on hybrid interconnector between Belgium and Denmark

System operators Elia (Belgium) and Energinet (Denmark) are to continue collaborating on the implementation of what could become a world first: the first undersea connection between two artificial energy islands which will be able to exchange power between the two countries and at the same time transport electricity from offshore wind farms to the mainland.

  • A preliminary study has shown that the project is both socioeconomically and technically feasible and will result in significant CO2 reductions at a European level.
  • The project could be a world first: if it goes ahead, it will serve as a subsea connection between two artificial energy islands in the northern and southern parts of the North Sea that will also transport the energy from wind farms to the mainland.
  • The hybrid interconnector will be called Triton Link, after the ancient Greek god of the sea.
  • Elia Group will also partner with Energinet via its German subsidiary 50Hertz on a similar project that will link Denmark and Germany.
