farms or other large –scale offshore installations
or
– operation of large offshore wind farms above a specific
size, e.g. 100 MW

consideration for financial or technical capacity?
New Offshore Wind Tenders in Denmark
Compliance with tender
•
•
•
•
Compliance penalty
Bank guarantee placed as collateral for the penalty
400 mill. for Horns Rev 3 and 600 mill. for Kriegers Flak
Bank (first of declaration of intention and later of guarantee)
needs ratings with “Standard & Poors” of A-, with Moody’s” of
A3 and with “Fitch” of A-.
• Guarantee released when spent 1 bn. in establishment of
Horns Rev 3 or 1 ½ bn. on Kriegers Flak
• Question: Will the intended model on compliance penalty
influence interest in tendering the wind farms? Will this
affect the price offered?
New Offshore Wind Tenders in Denmark
Award criteria
• Lowest price is the only award criterion
• Open to include other criteria than price, if
– the criteria are reasonable and relevant
– contribute to increased competition
– without additional costs for the tenderer
• Question: What criteria other than price could be relevant ?
New Offshore Wind Tenders in Denmark
Financial terms
• The price supplement is the difference between the ”price
pr. kWh bid” and the spot price for electricity
• The supplement will be given for the first 20/30 TWh
• No price supplement in hours with negative spot prices
• Compensation for delayed grid connection and for limits on
production.
Questions:
• Is the supplement for 20/30 TWh the right level?
• Other comments?

Compliance with deadline for completing
the wind farms
The political energy agreement:
The two wind farms are in full production from 1 January 2020.
Questions:
• How can DEA ensure a fair and sufficient incentive to
complete the farms before 2020?
• Will an economic incentive/sanction affect the interest in the
tender?
• Will the incentive affect the price offered?
New Offshore Wind Tenders in Denmark
Capacity of the farms
A required minimum of 395/595 MW and a maximum of
405/605 MW for Horns Rev 3 and Kriegers Flak respectively.

New Offshore Wind Tenders in Denmark
Technical Project Description for both sites are published
– and we would like your comments!
Pre-investigations and EIA for:
Horns Rev 3, Project manager: Betina Haugaard Heron, Energinet.dk
Kriegers Flak, Project manager: Pernille Skyt, Energinet.dk
In brief we will present the technical project description for Horns Rev 3
and Kriegers Flak – our main question to you is:
• Will the current draft technical project description ensure the
flexibility necessary to select technical solutions for projects on Horns
Rev 3 and Kriegers Flak?
New Offshore Wind Tenders in Denmark
Technical Projects Descriptions – the overall objectives
The overall objectives of the published technical project descriptions
are:
• Provide description of the main technical parts: wind turbines,
park layouts, foundations design, inter-array cables and
installation methods.
• Use this as the technical foundation for the environmental impact
assessment
• Provide a combination of a “most likely” and a “worst case”
approach
• Enable the EIA to secure as high degree of flexibility as possible in
order to allow the concession winner to design and built the most
optimal offshore wind farm.
New Offshore Wind Tenders in Denmark
Horns Rev 3: Location of pre-investigation area
• App. 160 km2
• Has been reduced since February
2013
• The wind farm area will cover an
area of app. 80-90 km2
• Flexibility for coming developer
New Offshore Wind Tenders in Denmark
Kriegers Flak: Location of pre-investigation area
• Overall area: 250 km2
• Water depths 15 - 30 m
Distance to shore 15 km
• Distance to harbour 20-40 km
• Exclusion zone central in the area. Here
two-three platforms and export cables to
Denmark and Germany, will be
established
• 200MW turbines west of exclusion zone
(pre-investigation area: 70 km2)
• 400MW turbines east of exclusion zone
• (pre-investigation area: 110 km2)
 Flexibility for coming developer

Turbine foundations
Three main types are included:
• Monopile
• Gravitation
• Jacket
The different types of foundations have
different impacts concerning e.g.:
• Installation noise
• Seabed preparation
• Scour protection
• ‘Footprint’
• Hydrodynamic impacts
• Risk of ship collision
All of this will be covered in the EIA

Technical dialogue: Questions related to Geo Investigations
(UXO, geophysical, geological, geotechnical issues)
Note has been published summarizing the comments in anonymous form,
including answers or responses to the input.
In summary, the following suggestions have been included in the geotechnical
survey program:
• More CPTs at both sites
• Pressure meter tests
• Dynamic laboratory tests
• Acoustic Corer will not be part of the program
Expected publishing dates:
July 2013: Geophysical survey results
31. December 2013: Geotechnical factual reports
28. February 2014: Updated 3D geological models
New Offshore Wind Tenders in Denmark
Technical dialogue: Questions related to MetOcean
Note has been published summarizing the comments in anonymous form, including answers or
responses to the input. Additionally, methodology notes have been published.
In summary:
• No met-masts will be established at the two sites
• The level for MetOcean studies at the two sites will be identical, with natural differences as
existing data from the two areas varies.
• Some developers hold more detailed knowledge on MetOcean data than others in the two
areas. DEA and Energinet.dk will make efforts to equalize the advantage potential developers
may have compared to others.
• Estimations on productivity will not be part of the MetOcean studies.
• Certification of the conducted MetOcean studies, or a verification of a third party is sought.
• Notes describing the methodology for the MetOcean studies are published; please comment!
• Metocean studies will be completed as planned, late 2013.
New Offshore Wind Tenders in Denmark
Road map of the technical dialog 2013
• May 13: Kick-off conference.
• May 27 – 30: Invitation to participate in bilateral meetings.
• May 31: Deadline for written contributions regarding
Metocean.
• June 7: Deadline for written contributions.
• Go to www.ens.dk/offshorewind in order to read more about
the tenders and to subscribe to the newsletter.
New Offshore Wind Tenders in Denmark
Summary point
• The Danish Energy Agency is open to hearing all relevant
proposals and input to ensure that the tendering procedures
reflect current market conditions.
• These may be proposals for contract terms, etc. which may be
able to reduce or increase the price, or enhance knowledge
about market conditions of significance to the price in the
tendering period.
