Borkum West phase 1 Developer Offshore-Stiftung Number of Turbines 12 Location 45km N of island of Turbine Rating (MW) 5 Borkum, North Sea Online 2007 Turbine Manufacturer Prokon Nord, Repower, Enercon Capacity (MW) 60 Foundation Type Steel Tripod Water Depth (m) 30 Status Firm Plan Distance to Shore (m) 46 Under development by Prokon Nord GmbH. The planned location of the offshore wind park "Borkum West" is approx. 45 km north the island Borkum between the operating running areas for the sea-going vessels. The project is divided in a pilot phase with approx. 12 turbines and a following development phase with 208 WEA. This corresponds to an installed achievement of approx. 60 MW for the pilot and approx. 1,000 MW for the development phase. Further 196 turbines planned of 5 MW. Total investment costs for this phase are approximately 2 billion. The plan is that Enercon, Multibrid and REpower each deliver four turbines to the project by The approved project Borkum West phase 1 was bought by the "Stiftung der deutschen Wirtschaft für die Nutzung und Erforschung der Windenergie auf See (Offshore-Stiftung)" ( Foundation of the German economy for the utilization and research of offshore wind-energy (offshore foundation) ). The project aims to intensify the ecological and technical research and by that start up the urgently necessary development of wind-energy-production at the North and Baltic Sea. The Federal Ministry for Environment, Nature Protection and Nuclear Safety (BMU) as the concerned Federal Ministry picked up that postulation and invited all affected economic branches for a meeting at the Hannover Fair and outlined a first model for a testing field. The erection of a testing field to support the German offshore wind-energy development has been appreciated and considered urgently necessary by representatives of manufactures of windturbines of the 5 MW class (Enercon, REpower, Multibrid), the VDMA, GMT, BWE, OFW and the WVW. All participants assured their willingness to collaborate on the development of a concept, which secures the financing of environmental and technical research

18 as well as wide social acceptance of offshore wind-energy. For the formulation of such a concept a working-group has been founded. The goal of the foundation was to create an institution, which bundles and takes into account as many parties of the offshore wind-energy industries as possible and to create a high degree of acceptance within the publicity. Experiences with foundations in different parts of the society make clear that by the structure of the organisation and the structure of financing this goals can be fulfilled and long-term goals can be followed, independent from political dependencies and changes. Aim of the foundation is the reimbursement of environmental- and climate protection by a improved research and development of wind-energy at the German North- and Baltic-Sea. To this end the foundation shall encourage 1. the technical research, the development and the innovation of offshore wind-energy subject to energy transportation to the costumer, 2. the accompanying research of consequences of construction, operating and deconstruction of offshore wind turbines, including their grid connexion, to the maritime environment and the ecological optimization of system engineering of offshore wind turbines, 3. research of suitability and effectiveness of public instruments for the encouragement of offshore wind-energy subject to a improved environmental- and climate protection, 4. the exchange and the transfer of knowledge of offshore wind-energy between science, economy and public or private parties. The model of a foundation reduces risks that may appear by the erection and the operating of such a testing field and distributes all rest-risks equably to all actors by distributing the different aspects of erection and operating of the testing field on the institutions.

DanTysk phase 1 Developer GEO Ltd Number of Turbines 80 Location Dan-Tysk, 45km west of Turbine Rating (MW) 5 Sylt, North Sea Online 2013 Turbine Manufacturer N/A Capacity (MW) 400 Foundation Type Steel tripod Water Depth (m) 30 Status Possible Distance to Shore (m) 50 The project is located outside of 12 mile zone in North Sea, on the German/Danish border. The total area for all phases of wind farm site is 600 km2. Developed by GEO Ltd, the planning area identified by GEO was classified in the published strategy paper of the Federal Government as a potential suitability area for offshore wind developments. The first phase will see 400 MW, 80 turbines of 5 MW each, 50 km from the coast. The second phase will add 1,100 MW to the project through MW turbines. The planned 5 MW wind energy plants will have a maximum overall height of 150 m and a rotor diameter of approx. 110 m. The turbines will probably have tripod foundations due to the water depth at the site (30 m).

20 Ems Emden (Emder Haven) Developer Enova Number of Turbines 1 Location Industriehafen Emden, Turbine Rating (MW) 4.5 North Sea Online 2004 Turbine Manufacturer Enercon Capacity (MW) 4.5 Foundation Type Mono-Pile Water Depth (m) 2 Status Operational Distance to Shore (m) 0.4 This 4.5 MW Enercon E-112, with a rotor diameter of 114 metres, is also the world's largest wind turbine ever erected in the water, and the fourth E-112 installed since the first prototype in August 2002 at Egeln near Magdeburg. The direct-drive prototype, with a hub height of 108 metres, is sited in the river Ems about 40 metres behind a coastal dyke. The three previous onshore prototypes all use concrete towers, with a 'standard' hub height of 124 metres; this type of tower is built like a factory chimney, with a so-called slidingshuttering construction, which involves six weeks' work on-site and a further four weeks to dry. The average wind speed at hub height for the offshore prototype has been calculated at 8.6 metres/second, sufficient to generate an estimated energy 15 million kwh annually.

The southern area of the development has an area of 904 square km, and the northern section 1526 square km. This gives a total project area of approximately 2430 square km. 11 separate construction phases are planned for the project, and development will start in the south of the area. The project will take a lot of planning, and first construction at the site is not expected before 2015, and full completion of the wind farm will be in The Forseti development is the biggest planned offshore wind farm in the world. If it were to use 5 MW turbines, it would be a massive 8750 MW if the project is developed it is likely that higher capacity turbines would be used, making the development bigger than 10 GW!

In the first phase, 80 turbines rated at 5 MW each are planned, over an area of 130 km2. The power will not be sold on, but instead used to produce hydrogen through electrolysis. Tripod foundations will have to be used for the turbines because of the substantial water depth and rough sea conditions. The developer hopes that experience it gains from its other projects will pay-off and help them realise this project. In total the project is planned as 4000 MW.

The original development plan called for approximately 100 MW of capacity from 30 turbines rated at 3 MW or above. Construction was initially scheduled for 2004 and the project was due online in 2005, however this schedule has slipped and a construction date of 2006 is currently planned. Development costs could run as high as 130 million because of the challenging nature of the site. The project calls for three 33 kv cables to shore each bringing power from groups of 10 turbines. The cables would link to a new substation on shore. There will be a single 132 kv line to take the produced power to the local grid.
