Selected Priority Projects

The List of Priority Interconnection Projects was established in 2018 following the 3rd Summit of the Three Seas Initiative in Bucharest. This List encompasses infrastructure projects within the critical realms of the 3SI: transport, energy, and digitalization.

The primary goal of introducing this List was to collaborate to secure the required financial resources for the 3SI projects, including identifying potential EU and other funds for their execution. Interested parties were urged to work together to acquire the financial resources needed for implementing these projects, including EU and other funding sources.

Initially comprising 48 projects in 2018, the List had expanded to 143 by 2024. These projects were put forth by 13 countries participating in the 3SI, and after the 2024 Vilnius summit, the Republic of Moldova and Ukraine also submitted projects, as both hold the status of associated participating states in the 3SI. The majority of the projects involve multiple states within the Central European region. As of now, most projects have been proposed by Croatia (33), Hungary (17), Poland (11), and Latvia (10). In contrast, the Czech Republic (2), Bulgaria (4), and Estonia (6) have submitted fewer projects.

Of the total projects, 51% pertain to transport, 39% to energy, and 10% to digitalization. The projected cost for their implementation stands at EUR 111 billion. Annually, a comprehensive report on their progress is presented during the Three Seas Initiative summit, ensuring stakeholders are well-informed. This report is easily accessible at the following link: https://projects.3seas.eu/report.

The inclusion of a project on the List does not inherently ensure additional financing but rather signifies the state’s commitment to potentially implementing a given investment.
