Article 4 of Regulation (EU) No. 347/2013 defines a Project of Common Interest (PCI) as one that has significant benefits for at least two member states, contributes to the integration of the electricity markets and to greater competition within the European Union, improves the security of energy supply, increases the amount of electricity generated from renewable energy sources (RES) and reduces CO2 emissions.
This Regulation sets out that in order for an electricity transmission and/or storage project to be eligible as a PCI, it must be included in the Ten-Year Network Development Plan (TYNDP) drawn up by ENTSO-E in compliance with Reg. (EC) no. 714/2009, which is the step immediately prior to the PCI selection process conducted by the European Commission. At the end of the process to select PCI projects, the European Commission publishes the list of the projects selected (PCI Union List), pursuant to EU Regulation no. 347/2013.
The third PCI list was published in November 2017 on the European Commission's institutional website for energy infrastructure. Having obtained the opinions of the European Parliament and of the Council, the list came into effect on 7 April 2018.
Following the process to select the projects submitted for inclusion in the third PCI list, the following development projects proposed by Terna were identified.
