Avedøre wind turbines, selection of locationAvedøre wind turbines, selection of location

As DONG Energy erects many wind turbines off shore, it is important to be able to test the wind turbinesit is important to be able to test the wind turbines.

Therefore, it is necessary to have a demonstration site with easy access for our employees.

Consequently, options for location in the Greater Copenhagen Area were considered.

The wind regime at Avedøre Holme bears close resemblance to the offshore wind regimeThe wind regime at Avedøre Holme bears close resemblance to the offshore wind regime.

Thus, the idea of erecting demonstration wind turbines at Avedøre Holme was born.

Avedøre wind turbines, the approval processsupreme authority

The approving authority for offshore wind turbines in Denmark is the Danish Energy Agency (ENS)Agency (ENS).

Usually, offshore wind turbines must be submitted for tender through the ENS, similar to eg Horns Rev 1 and 2to eg Horns Rev 1 and 2.

Offshore demonstration projects, however, are not subject to tender, but must still be approved by the ENSapproved by the ENS.

The ENS is the supreme authority and coordinates the approval process with other relevant authorities.relevant authorities.

Avedøre wind turbines, the approval processAvedøre wind turbines, the approval processBefore the EIS and the application for the wind turbines were submitted to the ENS, DONG Energy was in close contact with several stakeholders for contributions, and the below follow‐up committee was established, which among others include :committee was established, which among others include :

• Municipality of Hvidovre• Avedøre Wastewater Services• AV Miljø (waste deposit)A d k CHP l• Avedøreværket CHP plant

• The local dike guild• Representatives for the industrial area at Avedøre Holme• The local wind turbine guild – Hvidovre VindmøllelaugThe local wind turbine guild  Hvidovre Vindmøllelaug• Brøndby Harbour, yacht club/kayak club.

Furthermore, sail trips to the Middelgrunden were arranged to visit a similar project.

From the very beginning, it has been important to involve all stakeholders to create a sustainable project and to hear everyone's point of view – including the external controlling authorities.

The focal areas in the EIS were influenced by the follow‐up committee and were intended toThe focal areas in the EIS were influenced by the follow up committee and were intended to disclose the impact on the following environmental aspects:

• Coastal morphological conditions• Marine biological conditions• Marine biological conditions• Bird life• Protected species• Visualisation• Noise• Noise• Wake effect and reflection• Cultural historical conditions• Recreational conditions• Sailing/fishing• Sailing/fishing• Aviation• Planning• Safety.

Of the examined aspects, only the Protected species involve a potential impact:

The green toad.

The toad is listed in Appendix IV of the EU Habitats Directive and is under special protection.
