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

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

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)

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

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

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!

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

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
