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
Analysis of how to promote competition on the establishment
of large scale OWF
The Danish Ministry of Climate and Energy has commissioned an
analysis by Deloitte on the promotion of competition on the
establishment of large scale offshore wind farms in Denmark.
The object is to perform an analysis of the Danish tender model
from an economic and corporate financial perspective as welle as to
make recommendations for which tendel models that are appropriate
to use on future calls for tenders for offshore turbine farms so as
to ensure the highest extent of competition about the concessions
put up for tender.
The overall reporting consists of the
summary, a primary report in Danish and two
background reports in English. The primary report contains an
overall presentation of the results of the individual sub-analyses.
Background report 1 contains a detailed
analysis of the framework conditions for calls for tenders for
offshore turbine farms in selected EU countries including Denmark,
Great Britain, Germany and Holland.
Background report 2 contains an analysis and
assessment of the competitive conditions' significance to the
future capital costs of offshore turbine farms as well as their
significance to the calls for tenders and the demand for
establishment of offshore turbine farms.
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. This report was updated and published in
Danish in April 2011. 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.
OWF planning 2011:
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 area to be developed is the
area between Djursland and Anholt in the Kattegat. This site has
been awarded via a tender:
Anholt Offshore Windfarm.
Taking into consideration the costs involved, the committee
recommends that any expansion of offshore wind farm construction
should take place in the following 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.
