The offshore wind farm Deutsche Bucht is an offshore wind farm in the German Exclusive Economic Zone in the North Sea . The wind park has 31 wind turbines with a total output of 260.4 MW .
location
The wind farm is located 95 kilometers northwest of the East Frisian island of Borkum , west of the Veja Mate offshore wind farm that is already located there . The North Sea has a water depth between 38 and 40 meters there.
history
At the request of Eolic Power GmbH in Bremen on 23 June 2004, from 26 February 2010 the Federal Maritime and Hydrographic Agency , the construction and operation of 42 wind turbines on the basis of (BSH) Offshore Installations approved. In 2012 the project was sold by the Windreich company to the project developer Highland . The modified project with 31 wind turbines for 8.4 MW was approved by the BSH on June 30, 2017 , for the new developer British Wind Energy GmbH in Hamburg.
At the request of British Wind Energy GmbH (now: Northland Deutsche Bucht GmbH ) and on the basis of Section 118 (19) EnWG , the Federal Network Agency granted network connection authorization for two additional wind turbines in December 2016. Because of the special mono- bucket foundations , these two wind turbines are considered pilot projects and are preferably eligible for connection. In May 2018, the developer was given the approval to erect and operate the two wind turbines.
On July 15, 2018, a safety zone was set up at a distance of 500 meters around the locations of the planned wind turbines. The Dutch Van Oord Group was commissioned as the general construction company. The offshore work began in September 2018 with the installation of the foundations. The 31 monopiles manufactured in the Rostock plant of EEW Special Pipe Constructions were taken over by the crane lift ship Scylla at the new berth 4 of the Cuxport Terminal in Cuxhaven , transported to the construction site and brought there by the beginning of January 2019. The 26-meter-long transition pieces (transition pieces between the foundations and the actual wind turbine towers) that were also mounted on it were previously delivered from Spain to Cuxhaven and temporarily stored there. From spring 2019, the medium-voltage cables were laid between the foundations and the transformer platform installed at the beginning of April 2019 . From the beginning of June 2019, the 31 turbines were installed on the monopile foundations. On July 29, 2019, electricity was fed into the grid for the first time. At the end of September, all 31 monopile systems were already in operation.
The installation of the two other turbines should then take place, as the two mono-bucket foundations were still in production at Bladt Industries in Denmark in summer 2019 . Installation was scheduled for the fourth quarter of 2019. In March 2020, Northland Power announced that the mono-bucket foundations would not be installed due to technical difficulties, leaving 31 wind turbines.
financing
The investment volume of the project is 1.3 billion euros. KfW IPEX-Bank is responsible for financing the debt capital of EUR 900 million . The operator and investor is the Canadian energy supply company Northland Power . It represents a total of EUR 400 million in equity.
Wind turbines
The wind farm is expected to produce around 1,000 gigawatt hours of electricity annually. 31 wind turbines of the type MHI Vestas V164 are used . These have an output of 8.4 MW and a rotor diameter of 164 meters.
Network connection
The wind turbines are connected to a transformer platform in the wind farm via medium-voltage cables , which transforms the three-phase alternating current (three-phase current) from 33 kV to high voltage of 155 kV. From there, the electricity is fed to the BorWin2 offshore HVDC system operated by the transmission system operator Tennet TSO via a submarine cable connection . The Veja Mate and Albatros offshore wind farms are also connected to the BorWin beta converter platform . After conversion into direct current , the transmission takes place over 200 km (of which 125 km submarine cable and 75 km underground cable ) to the converter station Diele bei Diele (Weener) . The BorWin2 offshore HVDC system was supplied by Siemens , is designed for a connected load of 800 MW and went into operation in 2015.
business
Northland Power uses a site in Eemshaven as a maintenance and service base.
