Transmission system operator, 50Hertz, has connected the offshore wind farms Wikinger and Arkona off the island of Rügen to its transmission grid just in time for their commissioning.

The Wikinger offshore wind farm is operated by Iberdrola while Arkona is operated by E.ON and Equinor.

After three years of construction and a total investment volume of approximately EUR 1.3 billion, renewable energy is now flowing to the Lubmin substation during trial operation. From here it is supplied to the consumers via three 90 kilometers long submarine cables.

We congratulate E.ON and Equinor for the successful commissioning of their first wind farm in the German Baltic Sea and are proud of our cooperation as partners in the construction of the joint Arkona offshore substation”, said 50Hertz CEO, Dr Frank Golletz. “This offshore platform has set a new standard. We will also continue the good European relationship during the operation of the wind farm. We would especially like to thank the Federal Maritime and Hydrographic Agency (BSH) and the State of Mecklenburg-Western Pomerania, who always act as reliable supporters for the offshore projects and their connection. We are also counting on this well-established cooperation for future projects.

The connection of offshore wind farms Wikinger and Arkona, currently the largest investment project of 50Hertz, started in 2015 and is made at the Lubmin substation.

For the first time in the Baltic Sea, a grid connection was implemented as a 220 kV three phase current system, enabling a higher power transfer. Until now, the connections of offshore wind farms in the German Baltic Sea consisted of 150 kV three-phase cable systems. At the Lubmin substation, the current is transformed to 380 kilovolts and fed into the 50Hertz transmission system, the company explained.
