Germanys offshore strategy

• Actual Status
• Offshore wind energy foundation
• Research new government continues support
• EEZ identification of protected areas and
  particularly suitable areas
• Grid Integration
• Follow-up of Copenhagen Strategy

3
Actual Status

• 11 applications have been approved (EEZ)
• Long-term spatial planning started
• 10 wind turbines with min. 4,5 MW installed
• Renewable Energy Sources-Law (EEG) revised gt
  next report 2007
• Dena grid study, part II to come

4
The Feed-in law (EEG)

• Priority feed-in for RES guaranteed
• Guaranteed payment 20 years
• Tariffs depending on
• - distance to shore, water depth and average
  annual wind speed
• Degression 2
• Wind offshore Wind onshore
• - 1-12 years 9.1 Cts/kWh - 1-5 years 8.7
  Cts/kWh
• - 13-20 years 6.19 Cts/kWh - 6-20 years 5.5
  Cts/kWh

Offshore Wind Energy Foundation

• Set up by industry
• Target test field by 2007
• 12 wind turbines in 5 MW range
• Technological research
• Ecological research
• Knowledge exchange and transfer
• Project available (all licences granted)

6
Research on offshore wind energy

• 15-20 million euro per year for wind technology
  (mainly offshore) and ecological research
  connected to offshore wind farms
• Monitoring platform in operation, 2 planned
• Publication of TU Berlin on research findings

North Sea Potentially suitable and protected
areas

Findings of dena grid study, part I

• Grid integration of wind energy is possible
• upgrading of existing overhead lines
• construction of new extra-high voltage lines
• implementation of additional control units
• transitional technical solutions available
• no additional conventional power stations
  needed(balancing and reserve power)
• minor costs for private households

11
Grid study lessons learnt

• Involve all parties (Governments/TSO/industry)
• Review of RES scenarios critical
• Electricity trade scenarios relevant
• Technical solutions required
• More research on optimisation measures
• Wrong assumptions and lack of consideration of
  optimisation will lead to consecutive faults in
  other studies (e.g. European Studies)
• late grid expansion will have negative effects on
  RES-development!

12
Follow-up of Copenhagen Strategy

• Germany will invite for a follow-up
• Time-frame early 2007 (under German
  EU-presidency)
• Topics still to be decided, emphasis on grid
  integration
• Target develop an EU-Action Plan for offshore
  wind energy

13
Outlook

• Follow-up study on grid integration of offshore
  wind energy planned by German Energy Agency
  (dena)
• Optimisation of wind power systems and grid
  operation towards more flexible systems
• Research programme to be continued
• Testing field to be realised by Offshore
  Foundation
• First real Offshore Windfarms to be in
  operation in 2007 ? 2,000 3,000 MW in 2010
