Regulation (EU) No 347/2013 of the European Parliament and of the Council of 17 April 2013 on guidelines for trans-European energy infrastructure and repealing Decision No 1364/2006/EC and amending Regulations (EC) No 713/2009, (EC) No 714/2009 and (EC) No 715/2009 is intended to facilitate the timely development and interoperability of trans-European energy networks (TEN-E).

The regulation gives priority to twelve strategic trans-European energy corridors and areas (for electricity, gas, oil or thematic areas, such as smart grids or a carbon dioxide network) and provides criteria to identify projects of common interest (i.e. cross-border projects or projects which benefit two or more Member States) necessary to implement them, which may be eligible for EU funding under the "Connecting Europe Facility" financing instrument. The regulation also provides for new, more transparent and accelerated procedures to grant permits for such projects, which should generally not exceed 3.5 years. In addition, it lays down rules on the possible cross-border allocation of construction costs for infrastructure projects of common interest.
The Commission will adopt a first EU-wide list of projects of common interest on the basis of regional lists by 30 September 2013. Subsequent lists will be drawn up every two years. Six months after the adoption of the first list, the Commission will establish a publicly accessible infrastructure transparency platform containing information on projects of common interest. No later than 2017, the Commission will publish a report on the implementation of these projects.

The regulation will enter into force on 15 May 2013.
