Renewable Energy Wind - On the Effect of Offshore Wind Farms on the Atmosphere and Ocean Dynamics - page 11

Fig. 2.2 Germany ' s part of the North Sea, continental shelf, exclusive economic zone. Colors
show water depths with a maximum of 60 m. Area of EEZ in the North Sea spans around
28,600 km 2 . Illustration obtained from BSH

These scenarios deal with different marine management perspectives of the
EEZ. One of these scenarios, precisely an extreme scenario, is disposed and
presented in this topic in Chap. 6 to estimate possible changes of the North Sea in
case of intense offshore wind farming.
Nowadays, four offshore wind farms are in operating state (BMU 2013 ): alpha
ventus with 12 turbines, BARD Offshore 1 with 80 turbines, ENOVA Offshore Ems
Emden and Hooksiel Offshore each with one turbine. Several more are approved,
under construction, and under approval procedure. Figure 2.3 marks spaces within
the EEZ that are planned and used for OWFs. BARD Offshore 1 lies 90 km west of
Borkum; ENOVA nearshore, 0.1 km; and industry port Emden and Hooksiel
nearshore, 0.5 km north of Wilhelmshaven.
Offshore wind farm alpha ventus has a special role in this topic due to its status
as Germany

s first offshore wind farm and due to its attribute as test wind farm

'
and the focus of research. Details of this pregnant wind farm are given in the next
section.
