  1. German Policies on Offshore Wind Energy Cornelia Viertl / Jens Bömer Division KI I 3 / Hydropower and Wind Energy

  2. Germany’s 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 => 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

  5. 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

  7. North Sea: Potentially suitable and protected areas

  8. Baltic Sea: Potentially suitable and protected areas

  9. Offshore wind farm applications

  10. 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
