The power transmission system operators (TSOs) of Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland and Sweden, grouped together in the “Baltic Offshore Grid Initiative” (BOGI), have jointly released a roadmap to increase cross-border cooperation in the field of offshore wind energy and the associated electricity transmission grid infrastructure.
The strategic guidelines builds on the Vilnius Declaration signed in April 2024, when Baltic Sea countries had set an offshore wind capacity target of 26.7 GW 2030 and almost 45 GW by 2040. It analyses the potential for new hybrid interconnector projects and offshore energy multi-purpose hubs, to help unlock an offshore power potential in the Baltic Sea of 93 GW (compared to less than 5 GW installed currently). The roadmap focuses on four offshore hybrid projects (offshore wind park connected to several TSOs' grids), four offshore power interconnection projects, four onshore interconnection projects, and three cross-border hydrogen projects.
