Commission Delegated Regulation (EU) 2026/764of 1 December 2025amending Regulation (EU) 2022/869 of the European Parliament and of the Council, as regards the Union list of projects of common interest and projects of mutual interest

Commission Delegated Regulation (EU) 2026/764 of 1 December 2025 amending Regulation (EU) 2022/869 of the European Parliament and of the Council, as regards the Union list of projects of common interest and projects of mutual interest THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EU) 2022/869 of the European Parliament and of the Council of 30 May 2022 on guidelines for trans-European energy infrastructure, amending Regulations (EC) No 715/2009, (EU) 2019/942 and (EU) 2019/943 and Directives 2009/73/EC and (EU) 2019/944, and repealing Regulation (EU) No 347/2013 OJ L 152, 3.6.2022, p. 45, ELI: http://data.europa.eu/eli/reg/2022/869/oj. , and in particular Article 3(4) thereof, Whereas: (1) Regulation (EU) 2022/869 sets up a framework for identifying, planning and implementing projects of common interest (PCIs) that are required to implement the 11 strategic geographical energy infrastructure priority corridors identified in the fields of electricity, offshore grids, hydrogen and electrolysers, and the three Union-wide energy infrastructure priority areas for smart electricity grids, smart gas grids and carbon dioxide transportation networks. It also sets up a framework for identifying, planning and implementing projects of mutual interest (PMIs) developed by the Union together with third countries in the fields of electricity, hydrogen and carbon dioxide transportation networks. (2) Commission Delegated Regulation (EU) 2024/1041 Commission Delegated Regulation (EU) 2024/1041 of 28 November 2023 amending Regulation (EU) 2022/869 of the European Parliament and of the Council as regards the Union list of projects of common interest and projects of mutual interest (OJ L, 2024/1041, 8.4.2024, ELI: http://data.europa.eu/eli/reg_del/2024/1041/oj). established the first Union list of PCIs and PMIs as Annex VII to Regulation (EU) 2022/869. (3) The eligible projects proposed for inclusion in the Union list of projects of PCIs and PMIs referred to in Article 3 of Regulation (EU) 2022/869 were all assessed against the mandatory sustainability criterion for all project categories in accordance with the provisions in that is laid down in that Regulation. Only the projects that demonstrated significant contributions to sustainability were assessed further by the regional groups referred to in Article 3 of Regulation (EU) 2022/869 who confirmed that those projects meet the criteria laid down in Article 4 of that Regulation. (4) The Commission has assessed the candidate projects in view of the requirements of Article 3(5) of Regulation (EU) 2022/869. (5) The draft regional lists of PCIs and PMIs were agreed upon by the regional groups at technical-level meetings. (6) On 30 September 2025, the Agency for the Cooperation of Energy Regulators (ACER) issued its opinion on the consistent application of the assessment criteria and the cost/benefit analysis across regions. Subsequently, on 24 October 2025, the regional groups’ decision-making bodies adopted the final regional lists. Pursuant to Article 3(3), second subparagraph, point (a), of Regulation (EU) 2022/869, prior to the adoption of the regional lists, all proposed projects were approved by the Member States to whose territory the projects relate.

(7) The projects proposed for inclusion in the second Union list were subject to a public consultation. Moreover, organisations representing relevant stakeholders, including representatives of third countries, producers, distribution system operators, suppliers, local populations and consumer and environmental protection organisations were invited to the technical discussions in the regional groups and consulted on the projects proposed for inclusion in the Union list. (8) PCIs should be listed per strategic trans-European energy infrastructure priorities in the order laid down in Annex I to Regulation (EU) 2022/869. PMIs that are not required to implement the energy infrastructure priority corridors and areas set out in Annex I to Regulation (EU) 2022/869, should be listed separately as per the infrastructure category they belong to and by the region where they are located. (9) PCIs and PMIs should be listed either as stand-alone PCIs and PMIs or as a part of a cluster of several PCIs and PMIs where they are interdependent or (potentially) competing. (10) In the case of Cyprus and Malta regarding one interconnection for each of those Member States, which is provided for in Article 24 of Regulation (EU) 2022/869, the Commission has received the documentation required in accordance with paragraphs 1 and 2 of that Article. The respective projects were presented during the technical regional group meetings and the relevant documentation, excluding business secrets, was published. One interconnection for Malta and one interconnection for Cyprus, which are necessary to interconnect those Member States to the trans-European gas network, should, therefore, maintain their status as PCIs. (11) The Union list contains projects at different stages of their development, including the pre-feasibility, feasibility, permit-granting and construction. For PCIs and PMIs at an early stage of development, studies may be needed to demonstrate technical and economic viability and compliance with Union legislation, including environmental legislation. In this context, potential negative impacts on the environment should be adequately identified, assessed and avoided or mitigated. Moreover, relevant climate adaptation measures as regards the development of the projects should be identified and taken into consideration. (12) The inclusion of projects on the Union list is without prejudice to the outcome of the relevant environmental assessment and permit procedure. (13) Regulation (EU) 2022/869 should therefore be amended accordingly, HAS ADOPTED THIS REGULATION:

ANNEX VII THE UNION LIST OF PROJECTS OF COMMON INTEREST AND PROJECTS OF MUTUAL INTEREST (UNION LIST) (referred to in Article 3(4)) A. PRINCIPLES APPLIED IN ESTABLISHING THE UNION LIST (1) Clusters of PCIs and PMIs Some PCIs/PMIs form part of a cluster because of their interdependent, potentially competing or competing nature. The following types of clusters of PCIs/PMIs have been drawn up: (a) A cluster of interdependent PCIs/PMIs is defined as a Cluster X, including the following PCIs/PMIs:. Such a cluster is formed to identify PCIs/PMIs that are all needed to address the same bottleneck across country borders and that provide synergies if implemented together. In this case, all the PCIs/PMIs shall be implemented to achieve the Union-wide benefits; (b) A cluster of potentially competing PCIs/PMIs is defined as a Cluster X, including one or more of the following PCIs/PMIs:. Such a cluster reflects uncertainty as to the extent of the bottleneck across country borders. In this case, not all the PCIs/PMIs included in the cluster have to be implemented. It is left to the market to determine whether one, several or all PCIs/PMIs are to be implemented, subject to the necessary planning, permit and regulatory approvals. The need for the PCIs/PMIs shall be reassessed – also with regard to the capacity needs – in a subsequent PCI/PMI-identification process; (c) A cluster of competing PCIs/PMIs is defined as a Cluster X, including one of the following PCIs/PMIs:. Such a 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/PMIs, and therefore, it is decided that only one PCI/PMI has to be implemented. It is left to the market to determine which PCI/PMI is to be implemented, subject to the necessary planning, permit and regulatory approvals. Where necessary, the need for PCIs/PMIs shall be reassessed in a subsequent PCI/PMI identification process. All PCIs/PMIs are subject to the rights and obligations set under Regulation (EU) 2022/869. (2) Treatment of substations and compressor stations Substations and back-to-back electricity stations and compressor stations are considered parts of PCIs/PMIs if they are geographically located on transmission lines or next to pipelines, as the case may be. Substations, back-to-back stations and compressor stations are considered stand-alone PCIs and are listed explicitly on the Union list if their geographical location is different from transmission lines or pipelines, as the case may be. They are subject to the rights and obligations laid down in Regulation (EU) 2022/869. (3) Projects that are no longer considered PCIs or PMIs, and projects that have become part of other PCIs or PMIs Several projects included in the first Union list are no longer considered PCIs or PMIs for one or more of the following reasons: (a) the project has already been commissioned or will be commissioned by March of 2026 and would therefore not benefit from the provisions of Regulation (EU) 2022/869;

(b) according to new data, the project does not satisfy the general criteria; (c) the project was not re-submitted to be selected as a PCI/PMI; (d) a Member State to whose territory the project relates has not granted its approval; or (e) the project was ranked lower than other candidate PCIs/PMIs in the selection process. Those projects (with the exception of the projects commissioned or to be commissioned by March 2026) may be considered for inclusion on the next Union list if the reasons for non-inclusion in the current Union list no longer apply. Such projects are not PCIs or PMIs but, for reasons of transparency and clarity, are listed with their original PCI or PMI numbers in part C of this Annex as Projects no longer considered PCIs or PMIs. Some projects included in the first Union list became, during their implementation process, integral parts of other (clusters of) PCIs or PMIs. Such projects are no longer considered independent PCIs or PMIs but, for reasons of transparency and clarity, are listed with their original PCI or PMI numbers in part C of this Annex as Projects that are now integral parts of other PCIs or PMIs. (4) Non-eligible parts of the PCI/PMI projects Some PCI/PMI projects include one or more non-eligible investments. These following investments shall not be considered as part of the Union list: (a) internal reinforcements for the MEDLINK project (part of PMI 1.35), namely the AC transmission line between Annaba and Tougourt in Algeria, and the AC transmission line between De Jebil and Marsa Dhib in Tunisia; (b) internal reinforcements for the Interconnector between Subotica (RS) and Sándorfalva (HU) (part of PMI 2.12), namely the overhead line between Novi Sad 3 to Sombor 3, the overhead line between Srbobran and Sremska Mitrovica 2, and the reconstruction of substation Subotica 3; (c) internal reinforcements for the Interconnection between Wadi El Natroon (EG) and Mesogeia/St Stefanos (EL) [currently known as the GREGY Interconnector] (part of PMI 2.13) – internal sections in EG; (d) internal reinforcements for the interconnection between Bobov Dol (BG) and Leskovac 2 (RS) [currently known as the Central Balkan Corridor] (part of PMI 2.26), namely the upgrade of the overhead line between Nis 2 and Krusevac 1, the upgrade of substation Krusevac 1, the upgrade of the overhead line Krusevac 1 and Kraljevo 3, the upgrade of the overhead line between Kraljevo and Pozega, the new Pozega substation, the new overhead line between Jagodina and Pozarevac, the upgrade of the overhead line between Pozega and Vardiste, and the new substation in Pozarevac 3; (e) internal sections of the Spanish backbone (part of PCI 9.1.3): Coruña – Zamora, Huelva – Algeciras, Castilla y León (between Zamora – Haro), Guitiriz – Zamora, and the Castilla La Mancha and Madrid connection; (f) the Freiburg – Offenbach internal section in Germany (part of PCI 9.2.1); (g) the Limburg area section and its connection to the North-South backbone in the East of NL (part of PCI 9.6);

(h) the internal section in Germany starting close to Bremen and going towards Hanover (part of PCI 9.7.4); (i) the internal section in France from Port-de-la-Nouvelle via Barbaira (part of PCI 9.27.2); (j) the internal section in France Bordeaux – Lussagnet (part of PCI 9.27.3); (k) the internal section in Germany starting close to Bremen and going south (part of PCI 9.28); (l) the internal section in UK from Bacton to the internal UK hydrogen network (part of PMI 9.35); (m) the internal sections in Tunisia of the North Africa Hydrogen Corridor (part of PMI 10.12); (n) the internal section in Sweden connecting Kiruna to Luleå of the Nordic Hydrogen Route – Bothnian Bay (part of PCI 11.1); (o) the internal sections in Finland (geographical references are given as indications): Mäntsälä, Imatra, Kouvola, Kotka; the internal line of the Nordic-Baltic Hydrogen Corridor in LT connecting to Klaipėda (part of PCI 11.2); (p) the section Sweden – Finland and the connection of the Baltic Sea Hydrogen Collector to Gotland island (part of PCI 11.3). (5) Numbering of the projects on the Union list Projects that were included in the first Union list shall retain their original PCI/PMI number in the current Union list. Projects that are newly included in the current Union list shall be assigned a new unique PCI/PMI number. B.
