• (3)The proposed electricity transmission and storage projects of common interest falling under the energy infrastructure categories set out in point (1)(a), (b), (c), (d) and (f) of Annex II to this Regulation shall be part of the latest available Union-wide ten-year network development plan for electricity, developed by the ENTSO for Electricity pursuant Article 30 of Regulation (EU) 2019/943. The proposed electricity transmission projects of common interest falling under the energy infrastructure categories set out in point (1)(b) and (f) of Annex II to this Regulation shall derive from and be consistent with the integrated offshore network development and grid reinforcements referred to in Article 14(2) of this Regulation.

• (4)From 1 January 2024, the proposed hydrogen projects of common interest falling under the energy infrastructure categories set out in point (3) of Annex II to this Regulation are projects that are part of the latest available Community-wide ten-year network development plan for gas, developed by the ENTSO for Gas pursuant Article 8 of Regulation (EC) No 715/2009.

• (5)By 30 June 2022 and subsequently for every Union-wide ten-year network development plan, the ENTSO for Electricity and ENTSO for Gas shall issue updated guidelines for inclusion of projects in their respective Union-wide ten-year network development plan, as referred to in points (3) and (4), in order to ensure equal treatment and the transparency of the process. For all the projects on the Union list in force at the time, the guidelines shall establish a simplified process of inclusion in the Union-wide ten-year network development plans taking into account the documentation and data already submitted during the previous Union-wide ten-year network development plan processes, provided that the documentation and data already submitted remains valid.

• The ENTSO for Electricity and ENTSO for Gas shall consult the Commission and the Agency about their respective draft guidelines for inclusion of projects in the Union-wide ten-year network development plans and take due account of the Commission’s and the Agency’s recommendations before the publication of the final guidelines.

• (6)Proposed carbon dioxide transport and storage projects falling under the energy infrastructure category set out in point (5) of Annex II shall be presented as part of a plan, developed by at least two Member States, for the development of cross-border carbon dioxide transport and storage infrastructure, to be presented by the Member States concerned or entities designated by those Member States to the Commission.

• (7)The ENTSO for Electricity and the ENTSO for Gas shall provide information to the Groups as to how they applied the guidelines to evaluate inclusion in the Union-wide ten-year network development plans.

• (8)For projects falling under their competence, the national regulatory authorities and, where necessary, the Agency shall, where possible in the context of regional cooperation pursuant to Article 7 of Directive 2009/73/EC and Article 61 of Directive (EU) 2019/944, check the consistent application of the criteria and of the cost-benefit analysis methodology and evaluate their cross-border relevance. They shall present their assessment to the Group. The Commission shall ensure that criteria and methodologies referred to in Article 4 of this Regulation and Annex IV are applied in a harmonised way to ensure consistency across the regional groups.

• (9)For all projects not covered in point (8) of this Annex, the Commission shall evaluate the application of the criteria set out in Article 4 of this Regulation. The Commission shall also take into account the potential for future extension to include additional Member States. The Commission shall present its assessment to the Group. For projects applying for the status of project of mutual interest, third-country representatives and regulatory authorities shall be invited to the presentation of the assessment.

• (10)Each Member State to whose territory a proposed project does not relate, but on which the proposed project may have a potential net positive impact or a potential significant effect, such as on the environment or on the operation of the energy infrastructure on its territory, may present an opinion to the Group specifying its concerns.

• (11)The Group shall examine, at the request of a Member State of the Group, the substantiated reasons presented by a Member State pursuant to Article 3(3) for not approving a project related to its territory.

• (12)The Group shall consider whether the energy efficiency first principle is applied as regards the establishment of the regional infrastructure needs and as regards each of the candidate projects. The Group shall, in particular, consider solutions such as demand-side management, market arrangement solutions, implementation of digital solutions, and renovation of buildings as priority solutions where they are judged more cost-efficient on a system wide perspective than the construction of new supply side infrastructure.

• (13)The Group shall meet to examine and rank the proposed projects based on a transparent assessment of the projects and using the criteria set out in Article 4 taking into account the assessment of the regulators, or the assessment of the Commission for projects not falling within the competence of national regulatory authorities.

• (3) they shall establish the analysis to be carried out, based on the relevant multi-sectorial input data set by determining the impact with and without each project and shall include the relevant interdependencies with other projects;

• (4) they shall give guidance for the development and use of energy network and market modelling necessary for the cost-benefit analysis. The modelling shall allow for a full assessment of economic benefits, including market integration, security of supply and competition, as well as lifting energy isolation, social and environmental and climate impacts, including the cross-sectorial impacts. The methodology shall be fully transparent including details on why, what and how each of the benefits and costs are calculated;

• (5) they shall include an explanation on how the energy efficiency first principle is implemented in all the steps of the Union-wide ten-year network development plans;

• (6) they shall explain that the development and deployment of renewable energy will not be hampered by the project;

• (8) they shall take into account, at least, the capital expenditure, operational and maintenance expenditure costs, as well as the costs induced for the related system over the technical lifecycle of the project as a whole, such as decommissioning and waste management costs, including external costs. The methodologies shall give guidance on discount rates, technical lifetime and residual value to be used for the cost- benefit calculations. They shall furthermore include a mandatory methodology to calculate benefit-to-cost ratio and the net present value, as well as a differentiation of benefits in accordance with the level of reliability of their estimation methods. Methods to calculate the climate and environmental impacts of the projects and the contribution to Union energy targets, such as renewable penetrations, energy efficiency and interconnection targets shall also be taken into account;

• (9) they shall ensure that the climate adaptation measures taken for each project are assessed and reflect the cost of greenhouse gas emissions and that the assessment is robust and consistent with other Union policies in order to enable comparison with other solutions which do not require new infrastructures.

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;
