Ecofys WTTS has carried out an uncertainty assessment of a floating lidar device to support the Netherlands Enterprise Agency in driving down uncertainties and costs for developers for the next round of Dutch offshore tenders.
The aim of the study was to quantify the certainty with which the wind data, currently measured at the offshore wind farm zones Hollandse Kust and Borssele, can be used in calculation of final wind resource assessments, Ecofys WTTS said.
It said the unit assessed was a Fugro Oceanor AS Seawatch wind lidar buoy.
Ecofys WTTS added that the calculated uncertainty tables in the report can be used directly in wind resource assessments, together with the classification uncertainty and site-specific uncertainty components.
“The uncertainty tables apply specifically to the tested device although the results should be representative for similar devices, provided the International Energy Agency recommended practices are followed for the campaign design,” it said.
“A clearer understanding of the accuracy of wind measurements improves the energy production forecast of a proposed project and enables developers to drive down costs,” Ecofys WTTS added.
Ecofys WTTS is the wind measurement subsidiary of consultancy Ecofys.
