Berlin/Sassnitz, 29.10.2018 – Transmission system operator 50Hertz is making good progress for the Ostwind 1 offshore grid connection project, which started in 2015. After three years of construction, the submarine cable has been laid between the Wikinger offshore wind farm (Iberdrola) north of Rügen island and the connection point to the 50Hertz grid in Lubmin. Only residual works need to be performed now. The electricity, however, can already be fed into the grid.
“We wish to congratulate the Spanish company Iberdrola with the successful and early commissioning of the first wind farm in the German Baltic Sea. We are proud of our cooperation as partners,” said 50Hertz CEO Boris Schucht at the occasion of today’s official inauguration in Sassnitz. He also added: “This good European co-operation will successfully continue during the operational phase of this project and in the scope of the upcoming wind farm projects Baltic Eagle and Wikinger Süd. We are particularly grateful to the state of Mecklenburg-Western Pomerania, which is always a dependable supporter of the offshore projects and their connection, thus providing an active contribution to the energy transition”, Schucht continued.
50Hertz started its investment project of 1.3 billion in the summer of 2015. A special milestone was the technically challenging installation of the Wikinger offshore substation in August 2016. The wind farm is connected to the grid at the grid connection point in the Lubmin substation. For the first time in Germany, the grid connection uses 220 kV AC (alternating current) technology, making a higher electricity transmission capacity possible. 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 kV and fed into the 50Hertz transmission system.
Dr Henrich Quick, Head of offshore projects at 50Hertz, emphasised that the Baltic Sea is an attractive region for the wind power industry because of its high wind yield, which need not fear comparison with the North Sea. This is not in the least demonstrated by the fact that Iberdrola is already in the starting blocks for two new Baltic Sea projects. In the years to come, the Spanish company will construct wind farms “Baltic Eagle” and “Wikinger Süd”. A new foreign investor is Belgian company Parkwind, with its project Arcadis Ost 1. The three wind farms with a total capacity of 730 megawatts should be connected to the German transmission system by three cable systems. The grid connection of the wind farm called Ostwind 2 will run mostly in parallel with the Ostwind 1 power link, underlined Dr. Quick.
