Energy Infrastructure: EU Projects of Common/ Mutual Interest
10 December 2025
The European Union (EU) is committed to building a robust, integrated and sustainable energy infrastructure that supports its climate goals, energy security and market integration. Central to this vision is the Trans-European Networks for Energy (TEN-E) framework, which identifies, promotes and supports key cross-border energy projects within the EU as 'Projects of Common Interest' or 'PCIs'. The latest legislative update, Regulation (EU) 2022/869 (revised TEN-E Regulation), modernises the criteria and processes for identifying PCIs and introduces the concept of 'Projects of Mutual Interest' or 'PMIs' which are key cross-border energy projects between the EU and non-EU countries.
This briefing explores the purpose, selection criteria, and significance of PCIs and PMIs in light of the recently adopted 2nd PCI / PMI list. It also explains the key benefits to project developers and their investors of having a project listed on the PCI / PMI list, including enjoying the advantages of priority planning status and EU funding eligibility.
