Summary
• Good value of having the PCWG – and info on the web
• Shared responsibility between developers and manufactures– Energy in disc on a site - and turbines ability to extract this energy– Developers are advised by consultants to consider shear in full rotor
disc
• Example: Høvsøre test site back in business in winter months

Example: Høvsøre test site
Coastal near site – triggers internally BL (2-4% loss in AEP using HH)

Example: Høvsøre test site
What if a new wind farm was build at the Høvsøre site?
Low performance during winter should be expected!
Lidar measurements used for estimating performance - using actual diameter, hub height, wind rose etc.
