The Future of Offshore Wind

The deployment of offshore wind is growing and this development is expected to continue in the future. There are, however, several different marine planning interests and extensive analysis is conducted to identify the most suitable areas

Future Offshore Wind Turbine Locations – 2025
The report: ”Future Offshore Wind Turbine Locations – 2025” was published by The Committee for Future Offshore Wind Turbine Locations in April 2007. The report charts a number of possible offshore areas where offshore turbines could be built to an overall capacity of some 4,600 MW. Offshore wind turbines with a capacity of 4600 MW could generate approximately 18 TWh, or just over 8% of total energy consumption in Denmark. This corresponds to approximately 50% of Danish electricity consumption. The committee has examined in detail 23 specific possible locations each of 44 square kilometres to an overall area of 1012 square kilometres divided between 7 offshore areas.


 

Evaluating multiple interests
The committee assessed society’s interests in relation to grid transmission conditions, navigation, the natural world, the landscape, raw material exploitation etc. The committee also assessed options for connecting major offshore wind farms to the national grid, including examining the engineering, economic and planning options for landing power and the consequences for the underlying grid of the various potential areas for construction. At the same time the committee described scenarios for technological development of wind turbines capable of installation at greater sea depths. The committee attached importance to a planned and coordinated expansion of wind power and the transmission network with a view to obtaining the greatest possible economic benefits.

Seven offshore areas identified
The committee recommends that the first farms will be constructed at Djursland-Anholt in the Kattegat and Horns Rev in the North Sea. However, the prioritisation of Horns Rev depends on the closer evaluation of the nature conservation interests. From the economic point of view an expansion in Jammerbugten off the coast at Ringkøbing in the North Sea would be almost identical. Finally, the committee recommends locations at Store Middelgrund in the Kattegat and Kriegers Flak and Rønne Banke in the Baltic. 

Taking into consideration the costs involved, the committee recommends that any expansion of offshore wind farm construction should take place in the order. As described in "Future Offshore Wind Turbine Locations - 2025", when selecting potential areas, the recommendations for following a particular sequence in constructing sites are primarily based on the economic consequences regarding the additional costs for installation relative to water depths, the landing of power, the expansion of the land network and the expected energy production.
The report also discusses a number of areas, of which several have been designated previously, which the committee does not immediately believe to be suited to the installation of large scale offshore wind farms.
