“ANNEX VII The Union list of projects of common interest (“Union list”), referred to in Article 3(4)

A. PRINCIPLES APPLIED IN ESTABLISHING THE UNION LIST

(1) Clusters of PCIs

Some PCIs form part of a cluster because of their interdependent, potentially competing or competing nature. The following types of cluster of PCIs are established:

• a cluster of interdependent PCIs is defined as a “Cluster X, including the following PCIs:”. Such cluster has been formed to identify PCIs that are all needed to address the same bottleneck across country borders and provide synergies if implemented together. In this case, all the PCIs have to be implemented to realise the EU-wide benefits;

• a cluster of potentially competing PCIs is defined as a “Cluster X, including one or more of the following PCIs:”. Such cluster reflects an uncertainty around the extent of the bottleneck across country borders. In this case, not all the PCIs included in the cluster have to be implemented. It is left to the market to determine whether one, several or all PCIs are to be implemented, subject to the necessary planning, permit and regulatory approvals. The need for PCIs shall be reassessed in a subsequent PCI identification process, including with regard to the capacity needs; and

• a cluster of competing PCIs is defined as a “Cluster X, including one of the following PCIs:”. Such cluster addresses the same bottleneck. However, the extent of the bottleneck is more certain than in the case of a cluster of potentially competing PCIs, and therefore only one PCI has to be implemented. It is left to the market to determine which PCI is to be implemented, subject to the necessary planning, permit and regulatory approvals. Where necessary, the need for PCIs shall be reassessed in a subsequent PCI identification process.

All PCIs are subject to the same rights and obligations established under Regulation (EU) No 347/2013.

(2) Treatment of substations and compressor stations

Substations and back-to-back electricity stations and gas compressor stations are considered as parts of PCIs if they are geographically located on transmission lines. Substations, back-to-back stations and compressor stations are considered as stand-alone PCIs and are explicitly listed on the Union list if their geographical location is different from transmission lines. They are subject to the rights and obligations laid down in Regulation (EU) No 347/2013.

(3) Definition of “No longer considered a PCI”

The phrase “No longer considered a PCI” refers to projects from the Union list established by Regulation (EU) No 1391/2013 that are no longer considered PCIs for one or more of the following reasons:

• according to the new data the project does not satisfy the eligibility criteria;

• a promoter has not re-submitted it in the selection process for this Union list;

• it has already been commissioned or is to be commissioned in the near future and so it would not benefit from the provisions of Regulation (EU) No 347/2013; or

• it was ranked lower than other candidate PCIs in the selection process.

Such projects are not PCIs, but are listed with their original PCI numbers on the Union list for the sake of transparency and clarity.

They may be considered for inclusion in the next Union list if the reasons for not-inclusion in the current Union list no longer apply.

(4) Definition of “PCIs with double labelling as electricity highways”

“PCIs with double labelling as electricity highways” means PCIs which belong to one of the priority electricity corridors and to the priority thematic area electricity highways.
