FiftyHertz has a vested interested in capturing the Baltic sea’s wind energy potential. They are well on their way to completing the installation of the Jasmund offshore platform. This notable platform lies 40 km northeast of Rügen Island. Beyond its important role in connecting nascent wind farms to transmission and the electricity grid, we see additional benefits. This platform forms part of the Ostwind 3 grid connection system. The project will be completed and in full revenue service by September 30, 2026.
While it’s an early step, the Jasmund platform is a significant milestone. It is the first installation in the Baltic Sea for which 50 Hz is fully responsible as transmission system operator, both for the construction and for operation. The project is slated to receive an investment of €11.7 million ($13.65 million). It aims for a truly astounding installed capacity target of 500 megawatts (MW).
The platform will draw 300 MW of green power from the Windanker wind farm. This wind farm will start producing in October 2026. A submarine cable of more than 100 kilometers will connect the offshore platform to the land-based grid connection point at Stilowo. There, in the district of Vorpommern-Greifswald, a new substation of the German-Ukrainian corridor is already under construction.
The Ostwind 3 project covers a massive 109.2 km². This large barrier-free zone is located entirely within the German Exclusive Economic Zone of the Baltic Sea. The Jasmund platform is only one of the cool projects in development. That’s because two other offshore platforms are under construction, protective pipes being expertly laid, and a new substation taking shape near Gnewitz.
Stefan Kapferer, CEO of 50Hertz, emphasized the importance of this project:
“After Ostwind 1 and 2, Ostwind 3 is the next project in the sea area north-east 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. 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.”
As this very ambitious project moves forward, it is a reflection of 50Hertz’s dedication to advancing the development of renewable energy infrastructure and improving energy reliability. The company’s efforts are not only vital for Germany’s energy landscape but play a significant role in regional cooperation for sustainable energy development.
