Interest of government atoffshore Windpark Egmond aan Zee•Goal

Collect knowledge about windenergy at sea:

•Effects on nature and environment

•Technology

•Economy (efficient windpark)

•Therefore: Monitoring and Evaluation program

22 February 2007 EU Policy Workshop on offshore wind power deployment 7

Expected results bird investigation program:

• Order of magnitude for disruption of flight pattern, collision and barrier effect

• Comparison with on shore and extrapolation to further off shore possible

• Effect evaluation enabled and designparameters developed

22 February 2007 EU Policy Workshop on offshore wind power deployment 8

Expected results seals:

• Extra information about the use of the habitat

• Knowledge if the wind farm attracts or disturbs seals

22 February 2007 EU Policy Workshop on offshore wind power deployment 9

Expected results harbour porpoises:

• Information about the use of the wind farm area

• Reference data influence of wind farms

22 February 2007 EU Policy Workshop on offshore wind power deployment 10

Expected results benthos:

• Better understanding of underlying processes

• Effects of fishing stop on:– bottom fauna– refuge function– food production– Population set up in terms of age and species

22 February 2007 EU Policy Workshop on offshore wind power deployment 11

Expected results fish:

• Effects of the wind farm will be known

• Refuge function established or not

• Relevant processes known

22 February 2007 EU Policy Workshop on offshore wind power deployment 12

Expected results public opinion:

• Clear view on people´s opiniontowards the OWEZ

• Impression on influence of thewind farm on attractiveness ofEgmond aan Zee

22 February 2007 EU Policy Workshop on offshore wind power deployment 13

Expected results safety and ships:

• Insight in collision risks andconsequences of oil spills

• Insight in effects onshipping radar

22 February 2007 EU Policy Workshop on offshore wind power deployment 14

First results Monitoring program•Public opinion moving towards far more positive attitude

•No negative influence of OWEZ on tourists on the beach

•Piling caused no disturbance of birds

•Under water noise level during piling is known

•Wind resource available through measurements

•Zero measurements on seals finished

•Risks for vessels very limited

•Results available on www.noordzeewind.nl
