Future of offshore wind
Dr Jan Willem Wagenaar
Bergen, NORCOWE Grand summarizing conference15 September 2016
Offshore wind development NL
• Operational (357MW)– OWEZ 2006 108MW
– Amalia 2008 120MW
– Luchterduinen 2015 129MW
• Under construction (600MW)– Gemini 2017 600MW
• Planned tender (3500MW)– Borssele 2016 700MW
– Borssele 2016 700MW
– HKZ 2017 700MW
– HKZ 2018 700MW
– HKN 2019 700MW
Offshore wind development NL
• First tender Borssele– Won by Dong
– Cheapest offshore wind farm
• Next offshore wind farms expensive– Less favourable finance conditions
– Further from shore
• GROW 20 for 7– Growth through Research, development
and demonstration in Offshore Wind
– 5 year programme
– 20 partners
– 7 €c/kWh

• What are local conditions?– Wind conditions
– Turbulence & Shear
– Atmospheric conditions
• What happens in upper layers?
• What combination of meteorological and maritime conditions can be expected?
• How does near shore –land transition look like?
• Validation of models
Wind farm aerodynamics
• NL Borssele wind farm zone 1400MW wind farms
Directly North of Belgian wind farms
For sure: mutual interaction
• Effect vizualization Hasager EWEA 2015: Satellite
Hasager EWEA 2015: WRF
How big is this effect?
Weather Research and Forecasting model (WRF)
Case study: Borssele wind farm zone
Wind farm Aerodynamics• Wind farm wake effects Belgian wind farms on BWFZ: 4%
First estimation
BWFZ on Belgian wind farms: 2.7%
Detailed FarmFlow modelling
South-West direction dominant
• The proof of the pudding is in the eating Scanning LiDAR measurement campaign
Given the current developments in offshore wind and the plans for the future, this effect becomes more and more important
Facilities Key!
WindScanner
Scaled Wind Farm
• 10 Turbines (H=7.5m, D=7.6m)
• 4 Large meteo masts (18.9m)
• 10 Small meteo masts (7.5)
