The Kaskasi offshore wind farm of RWE Renewables Sweden AB located in the North Sea has been successfully connected to HelWin Beta.
The wind farm, located about 35 km north of Helgoland, has a capacity of 342 MW and a size of around 17 km². The 38 wind turbines are connected to a transformer platform in the wind farm, which transforms the three-phase current to a high voltage of 155 kV. After conversion into direct current, the transmission takes place over 130 km to the converter station in the Büttel substation.
