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:

        1. 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;
        2. 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
        3. 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)Projects that are no longer considered PCIs and projects that became part of other PCIs

        1. Several projects included in the Union lists established by Delegated Regulation (EU) No 1391/2013, Delegated Regulation (EU) 2016/89, Delegated Regulation (EU) 2018/540 and Delegated Regulation (EU) 2020/389 are no longer considered PCIs for one or more of the following reasons:
          • the project has already been commissioned or will be commissioned by March of 2022 and so it would not benefit from the provisions of Regulation (EU) No 347/2013,
          • according to new data the project does not satisfy the general criteria,
          • a promoter has not re-submitted the project in the selection process for this Union list,
          • a Member State to whose territory the project relates has not granted its approval, or
          • the project was ranked lower than other candidate PCIs in the selection process.

          These projects (with the exception of the projects commissioned or to be commissioned by March 2022) may be considered for inclusion in the next Union list if the reasons for non-inclusion in the current Union list no longer apply.

          Such projects are not PCIs, but are listed for reasons of transparency and clarity with their original PCI numbers in Annex VII(C) as Projects no longer considered PCIs.

        2. Furthermore, some projects included in the Union lists established by Delegated Regulation (EU) No 1391/2013 and Delegated Regulation (EU) 2016/89 became during their implementation process integral parts of other (clusters of) PCIs.

          Such projects are no longer considered independent PCIs, but are listed for reasons of transparency and clarity with their original PCI numbers in Annex VII(C) as Projects that are now integral parts of other PCIs.
