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

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.dkKriegers 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
• 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
• Overall area: 250 km2
• Water depths 15 - 30 mDistance to shore 15 km
• Distance to harbour 20-40 km

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 collisionAll 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 results31. December 2013: Geotechnical factual reports28. February 2014: Updated 3D geological models

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.
