The EnBW "He Dreiht" offshore wind farm is a planned offshore wind farm in the German Exclusive Economic Zone of the North Sea , approx. 85 km north of the island of Borkum and approx. 104 km west of the island of Helgoland . The term He Dreiht is Low German for he turns .
Planning history
Start of planning and original planning
The wind farm was originally planned by EOS Offshore AG from Varel , a joint venture between innoVent and wpd at the time . At the request of EOS Offshore AG on January 24, 2002 for the construction and operation of 119 wind turbines (WTs) of the 4.5 MW class, the wind farm was opened on December 20, 2007 with initially 80 WTs by the Federal Maritime and Hydrographic Agency (BSH ) approved according to the marine facilities ordinance . The approval for the remaining 39 wind turbines was rejected by the Waterways and Shipping Directorate North because the application did not provide an assessment of the cumulative risk of a ship colliding with the systems.
The approved sub-project was sold to EnBW Energie Baden-Württemberg in May 2008 . The now renamed EnBW Nordsee Offshore GmbH supplemented the required risk analysis on July 23, 2009. The approval for the 39 wind turbines was finally granted on February 22, 2010. The wind farm is to be built on an area of around 60 km² with water depths of 37 to 43 meters. The construction and operation of 119 wind turbines with a capacity of up to 5 MW each was planned. This would result in a total output of 595 MW. The permit for the older planning expired because, despite the extension of the deadline, construction work for the installation of the systems did not begin by June 30, 2017.
Current planning
The offshore wind farm has been running under the name EnBW He Dreiht since December 2012 ; the license holder is EnBW He Dreiht GmbH , based in Stuttgart (formerly: Varel). The current plans from April 2017 envisage the commissioning of the wind farm with a total output of 900 MW in 2025. 90 turbines with at least 10 MW each are planned.
In April 2017, EnBW secured a contract for 900 MW for He Dreiht . In the invitation to tender under the Wind Energy Offshore Act , EnBW offered 0.00 cents per kilowatt hour and thus secured grid connection capacity without claiming a market premium under the Renewable Energy Sources Act .
The connected load of 900 MW is connected to the BorWin5 offshore HVDC system . This means that the capacity of BorWin5 is exhausted. The 230 km long direct current connection to the grid connection point near Cloppenburg will be implemented using 110 km of submarine and 120 km of underground cables. The three-phase connection of the wind farm to the BorWin epsilon offshore converter platform will be made using a new 66 kV direct connection concept. With this concept, the 66 kilovolt cable harnesses of the wind turbines are connected directly to the converter platform. By eliminating the 155 kV three-phase submarine cable systems and wind farm transformer platform that were previously used , the overall costs of the BorWin5 grid connection system are reduced . The responsible transmission system operator is Tennet TSO .
