On 19 October 2011, the European Commission (EC) adopted the proposal for a Regulation on "Guidelines for trans-European energy infrastructure". It aims at ensuring that strategic energy networks and storage facilities are completed by 2020. To this end, the EC has identified 12 priority corridors and areas covering electricity, gas, oil and carbon dioxide transport networks. It proposes a regime of "common interest" for projects contributing to implementing these priorities and having obtained this label.
On 17 November 2010, the EC presented its energy infrastructure priorities for the next two decades, aimed at making networks fit for the 21st century. In the Communication, the EC defines EU priority corridors for the transport of electricity, gas and oil. This map of priorities will serve as a basis for future permit granting and financing decisions on concrete EU projects.
