Modern infrastructure with adequate interconnections and reliable networks is crucial for an integrated energy market where consumers can get the best value for their money. On 14 October 2013, the European Commis-sion adopted a list of 248 key energy infrastructure projects.

The list includes 132 projects in the field of electricity transmission and storage, 107 projects in the field of gas transmission, storage and liquefied natural gas (LNG), seven oil projects and two smart grids projects.

These Projects of Common Interest (PCIs) benefit from accelerated licensing procedures as well as improved regulatory conditions and may access financial support from the Connecting Europe Facility. Under this multi-annual programme, a budget of 5.85 billion has been allocated to trans-European energy infrastructure development for the period 2014-20.

For a project to be included in the list, it has to comply with the following criteria: significantly benefit at least two Member States, contribute to market integration and further competition, enhance security of supply, and reduce CO2 emissions. Once completed, the projects will help Member States to integrate their energy markets, diversify their energy sources and bring an end to the energy isolation of some of them. The projects will also enable the grid to take up increasing amounts of renewables and as a result contribute to reducing CO2 emis-sions.

The crucial role PCIs play in the security of supply in Europe was emphasized in the European Commission Communication of 28 May 2014 on a European Energy Security Strategy. Out of the 33 key security of supply infrastructure projects identified in this report, 31 are also projects of common interest.

The list of PCIs will be updated every two years, in order to integrate new vital projects and remove those that have become obsolete.

Updates of the project fact sheets assembled in this publication are available on-line via the interactive map located at: http://ec.europa.eu/energy/infrastructure/pci/pci_en.htm
