PHASING OUT NUCLEAR AND SPEEDING UP WIND Since deciding in summer 2011 to completely phase out nuclear energy by 2022, Germany has fully committed itself to a “path to the energy of the future – reliable, affordable and environmentally sound”. A rapid expansion of Germany‘s offshore wind capacity is foreseen, requiring opti­mal use of the practical experience obtained throughout the North Sea region.

COUNTRY-SPECIFIC OFFSHORE WIND TURBINE DESIGNS: RESPECTING HSSE AND MANAGING LIABILITIES What would you do if global targets for offshore wind were to add up to over 75 GW over the next eight years? Exactly: design a new offshore wind turbine and sell it! But that is easier said than done. Global offshore wind targets are rocketing sky-high and demand for offshore wind turbines is increasing accordingly. Since new locations will be in deeper waters and further offshore, interest in new innovative wind turbines has been growing.

Wind test site Lelystad celebrating second anniversary

The wind test site in Lelystad, Netherlands, is looking forward to celebrating its second anniversary on October 13th 2012. The test site helps wind turbine manufacturers in testing and developing their wind turbines by providing meteorological measurements and data connections to the turbines through a state-of-the art fibre-optics network. In addition to that, the test site makes use of new types of instruments such as LiDARs that can be interchanged with LiDARs for measurement campaigns outside the test site. Erik Holtslag, Operational Manager test site Lelystad at Ecofys, had this to say about the first results following almost 14 months of testing and measuring: “The results on turbine behaviour are promising, data availability has been above contractual expectations and quality, and interesting new meteorological insights have been gained. We are delighted with these results.”

Acutely managing the interfaces between installation contractors, for example, avoids unnecessary vessel waiting time. Since asset management potentially holds numerous other cost and safety benefits, Ecofys is currently developing an asset management system for the complete lifecycle of an offshore wind farm.

Cost price reduction One of the focal points in the offshore wind sector is cost price reduction in all its facets: wind turbine costs (including foundations and grid connection), installation costs, and operation and maintenance costs. All these factors can result in a lower offshore wind kWh price. The wind sector is currently experiencing a boom in product development to achieve such a cost price reduction. Enabling wind turbine manufacturers, construction companies and O&M parties to develop, innovate and test their newest technologies is an essential element in this process.
