In March, the European Parliament and Council have adopted the ‘Regulation on Guidelines for Trans-European Energy Infrastructure’. This legislation is another step towards the European objective of an internal energy market which will support the integration of renewable energies and promote the interconnection of energy networks. Integral part of the legislation is the identification of ‘Projects of Common Interest’ (PCIs) which will be subject to a European permitting regime and eligible for European funding. Many of the projects that are proposed for the first list of PCIs are subsea cables. The implementation of these projects will thus be another building block towards an expansion of offshore grid infrastructure in Europe, and towards improved international cooperation to achieve this.
