Selection process

Projects of Common Interest are selected in regional groups on the basis of well-defined criteria and through call for applications every 2 years.

The work on Projects of Common Interest (PCIs) is coordinated by regional groups, dedicated to each of the following types of energy infrastructure: electricity, offshore grid development, hydrogen and electrolysers, smart electricity grids, smart gas grids and CO2 networks, in line with the scope of the revised Trans-European Networks for Energy (TEN-E) Regulation. 

PCI identification and selection process

Projects are selected as PCIs on the basis of 5 criteria. They must

  • have a significant impact on at least 2 EU countries
  • enhance market integration and contribute to the integration of EU countries' networks
  • increase competition on energy markets by offering alternatives to consumers
  • enhance security of supply
  • contribute to the EU's energy and climate goals and they should facilitate the integration of energy from renewable energy sources

New PCI lists are established every 2 years since 2013.


Promoters of projects that are potentially eligible for PCI status can submit an application to the corresponding regional groups through open call for applications, launched by the Commission.

The regional groups assess the applications regarding their compliance with and relevance to the specific PCI selection criteria, as defined under Article 4 of the Regulation. Through this assessment, the PCI candidates are ranked by the Decision-Making Bodies of the regional groups.

EU- wide PCI list

The assessment results in a regional list of proposed PCIs, which the Commission adopts as an EU-wide list by means of a delegated act and submits to the European Parliament and the Council.

These institutions have 2 months to oppose the list, or they may ask for an extension of 2 months to finalise their position. The Parliament and the Council cannot request amendments to the list and if neither of them rejects it, the PCI list enters into force.

Establishing the first Union list under the revised Regulation

On 17 October 2022, the Commission kicked off the process for establishing the first Union list under the revised TEN-E Regulation with the first Cross-regional meeting on Projects of Common Interest and Projects of Mutual Interest. On the same day,  it opened the submission window for projects under all infrastructure categories. The call for applications was open until 15 December 2022.

The second cross-regional group meeting took place in Brussels on 8-9 December 2022 and another was organised on 6-8 February 2023. The following series of cross-border regional group meetings took place 13-24 March 2023 and 17-21 April 2023.

All meeting documents for these meetings are available in a dedicated CIRCABC.

Before starting the process establishing the first Union list under the revised Regulation, the Commission held on 7 October 2022 an informative session as part of the consultations on the cost-benefit analysis methodologies for the following infrastructure categories: hydrogen, electrolysers, smart gas grids, smart electricity grids, CO2 networks and energy storage. The list was adopted on 28 November 2023.
