Key cross border infrastructure projects

Projects of common interest (PCIs) are key cross border infrastructure projects that link the energy systems of EU countries.

They are intended to help the EU achieve its energy policy and climate objectives: affordable, secure and sustainable energy for all citizens, and the long-term decarbonisation of the economy in accordance with the Paris Agreement

This short video “What are the Projects of Common Interest?” explains it further.

Who can become a PCI ?

The project must have a significant impact on energy markets and market integration in at least two EU countries, boost competition on energy markets and help the EU's energy security by diversifying sources as well as contribute to the EU's climate and energy goals by integrating renewables.

The selection process gives preference to projects in priority corridors, as identified in the Trans-European Networks for Energy (TEN-E) policy.

PCI advantages

Projects of Common Interest benefit from 

  • accelerated planning and permit granting
  • a single national authority for obtaining permits
  • improved regulatory conditions
  • lower administrative costs due to streamlined environmental assessment processes
  • increased public participation via consultations
  • increased visibility to investors

They also have the right to apply for funding from the Connecting Europe Facility (CEF).

The PCI lists

Every two years since 2013, the European Commission draw up a new list of PCIs.

On 31 October 2019 the Commission published its fourth list of PCIs (EU) 2020/389, which contains 149 projects; 100 electricity transmission and storage, 6 smart grid deployment, 32 gas, 6 oil and 5 cross-border carbon dioxide networks.

In April 2020, the Commission published the technical document for the 4th PCI list, which provides a technical description of all projects, information on promotes and commissioning dates.

Before and during the implementation of PCIs, comprehensive impact assessments and public consultation processes are organised with a wide range of stakeholders, especially citizens and NGOs. The results of the public consultations are available here:
