The Swedish part of German utility Vattenfall says it wants more experience with deep-water offshore wind development and has bought the rights to a North Sea area off Denmark from German developer GEO Association for Energy and Ecology. Price for the purchase was not disclosed. The 600 square kilometre area earmarked for the Dan Tysk wind project, 70 kilometres northwest of the island of Sylt, is ideal as a test field, says Vattenfall Europe's Geraldine Schroeder. "Dan Tysk is of a size to eventually realise several offshore projects," she says. Vattenfall's pilot phase at Dan Tysk is scheduled to include 80, 5 MW turbines on a 71 kilometre section of the area. GEO had already received initial building permits from the German government for both a 400 MW plant and a 1100 MW plant during 2011-2013. Water depths at the site are approximately 31 metres. Before it begins building at Dan Tysk, Schroeder says Vattenfall is partnering with others, including German utilities E.ON and EWE, on a project to test 5 MW turbines at the nearby Borkum West site (Windpower Monthly, November 2006). The pilot project is scheduled to begin this year. The German environment ministry, meantime, is subsidising a research platform to help collect data on offshore wind development, to be located within ten kilometres of the Dan Tysk area, also this year. The Dan Tysk rights will be owned by a German subsidiary, Vattenfall Europe New Energy GmbH.
