Progress Report

The List of Priority Interconnection Projects was one of the main outcomes of the third Three Seas Initiative Summit held in Bucharest in 2018. It encompasses 48 projects focusing on three fields: energy, digital and transportation.

By implementing these projects, the participating countries aim to answer the needs and priorities of the member states and provide a substantial contribution to the overall objective of the Three Seas Initiative. 

These projects help to stimulate economic growth, develop north-south infrastructure corridor, level regional disparities within the EU and boost cohesion and unity in Europe. 

The update of priority projects is made annually and presented during the Three Seas Summits. The 2020 update of projects is currently in progress and will be made public in autumn 2020 before the event in Tallinn.
