Wind resource assessment for future Borssele offshore wind farm zone

Mapping offshore wind resource for Borssele wind farm zone

Published: 28/08/2015

As part of the preparations for the tendering of the Borssele offshore wind farm zone, expected to open at the end of this year, The Netherlands Enterprise Agency ( commissioned Ecofys to perform a wind climate assessment for the planned sites in the Dutch North Sea, close to the Belgian border. Since no specific on-site measurement records were available, the assessment has been based on the combined use of offshore wind measurement campaigns and mesoscale model data.

Data gathered by RWE and ECN at Meteomast Ijmuiden forms the primary basis of this wind resource assessment, extrapolated to the Borssele zone based on the 2015 KNMI KNW mesoscale model, as that was found to give the most accurate match at four offshore met mast datasets spread over the North Sea.

This report gives an indicative representation of the weather climate, showing a mean wind speed at 100 m MSL at the Borssele zone centre of 9.6 ± 0.5 m/s. All of the analysed trends are reasonable for the offshore site and consistent across the modelled heights. The outcomes of this study can be used by project developers as a basis for their bid, however, tender applicants are advised also to create their own assessment.
