Eight Baltic Sea electricity TSOs publish offshore system study to promote coordinated sea basin planning
The electricity Transmission System Operators (TSOs) of eight countries bordering the Baltic Sea today published the first comprehensive regional system study for offshore network infrastructure and offshore wind, marking a significant step toward coordinated sea basin planning in Europe.
The TSOs of Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland and Sweden – organised in the Baltic Offshore Grid Initiative (BOGI) – developed a study that moves from electricity transmission corridors to potential projects for the 2040-time horizon. The results show that the Baltic Sea region can become a clean energy hub, with around 13 GW of new cross-border interconnectors and up to 50 GW of additional offshore wind identified by 2040. These connections include point-to-point links between countries and strategic offshore nodes such as Bornholm, which could serve as future hybrid hubs. The market modelling indicates that these interconnectors would operate with high utilisation throughout the year and significantly reduce system costs, price peaks and CO₂ emissions.

Read MoreOstwind 3 grid connection project on the home stretch: Offshore platform precisely installed in the sea off Rügen
The expansion of the grid connection systems for connecting offshore wind farms in the Baltic Sea is progressing well. 40 kilometres northeast of the island of Rügen, an important stage in the 50Hertz Ostwind 3 project has now been successfully completed – the installation of the Jasmund offshore platform. It is to collect 300 megawatts from the Windanker wind farm from October, transform it to the voltage level of 220 kilovolts and transmit the electricity via a submarine land cable connection to the new Stilow substation in the Vorpommern-Greifswald district, which is still under construction.
Stefan Kapferer, Chairman of the Management Board of 50Hertz: “After Ostwind 1 and 2, Ostwind 3 is the next project in the sea area northeast of Rügen, which we will complete on time and within budget. We are also on track with the next OST-6-1 project with a transmission capacity of 927 MW, which serves to connect the Gennaker wind farm north of the Fischland-Darß-Zingst peninsula. Two offshore platforms are already under construction, the laying of protective pipes has begun, and a new substation near Gnewitz is taking shape. Overall, 50Hertz is making a significant contribution to reliably tapping the great wind energy potential of the Baltic Sea – in German waters, but also beyond in cooperation with Energinet from Denmark and, in the future, with other partners in the Baltic region.”

Read MoreApproval procedures for the Bornholm Energy Island project launched
An important milestone has been reached for the hybrid interconnector Bornholm Energy Island (BEI): first public consultations have started in both countries.
The transmission system operators 50Hertz and Energinet have jointly submitted an application to start the environmental impact assessment (EIA) to the Danish Environmental Agency SGAV for the “BEI Interconnector Bornholm-Germany.” To this end, in November 2025, the public on Bornholm and relevant stakeholders were invited to the first public consultation. In Germany, the first public consultation took place in April 2025.
Bornholm Energy Island is a European PCI project (project of common interest), and the approval procedures are therefore being carried out according to the European TEN-E regulation.

Read MoreLarge-scale order for Siemens Energy to realise Danish-German Bornholm Energy Island project
The joint Danish-German Bornholm Energy Island project is moving from the planning and development stage to the implementation stage. The two transmission system operators Energinet (Denmark) and 50Hertz (Germany) placed a joint order with Siemens Energy for the construction and turnkey delivery of four converter systems in total as well as other technical components on the Danish island Bornholm and the Danish island Zealand as well as on the German mainland. This marks the end of a six-month transition phase during which the joint project had to be paused due to the need for political regulation between the two countries involved.
The contract that is now concluded between Energinet, 50Hertz and Siemens Energy covers the design, the completion, transport, installation, testing as well as commissioning of the systems by the mid-2030s.
