Actors-Factors-Sectors

  • Technology challenges: deep sea, long lengths, infrastructure

requirements in the continental parts

  • Market challenges: reliable assessment of interconnections’ impact in

a changing electricity and energy market environment

  • Geopolitical risks: transmission infrastructure requires long-term

financial-political-social stability

  • TSOs-ENTSO-E: leadership role in the future development of

interconnections’ infrastructure

  • Internal – International – Intercontinental: steps and enablers
