Slide 1

Wind power variety: a profoundly variable, questionable and flighty wellspring of vitality Facts and insights from the biggest wind generator in Germany : E-ON

Slide 2

Power variety - every month circulated by E-ON

Slide 3

E-ON wind power variety throughout the year (theoritical max : 7.558 MW) Installed 7558 MW Daily max 6234 MW Daily min 8 MW Installed limit: 33.200MW including wind 7.558 MW (23%) Production: 271.300 MWh includ. wind 11.300 MWh (4,16%)

Slide 4

Delivered wind power: points of interest of variety per 15 min Gradient: 1000 MW/h

Slide 5

7500 MW > ½ Power: 5,1% of the time = 2,7 weeks > ¼ Puissance: 25% of the time = 13 weeks 18,5%

Slide 6

Forecasting of wind force is unsafe January: blustery season Max 80% Min 3% Accuracy of expectation : from - half to +100%

Slide 7

Sensitivity of windmills to framework soundness and Incapacity of the matrix to face windmill yield varieties Expansion of wind vitality in Germany is unrealistic without a vast participation, in light of the fact that electrical networks in neighboring nations are influenced by the flimsiness of wind vitality creation in Germany. Illustration : Nov fourth 2006, vast electrical power outage (wind insecurity included).

Slide 8

Congestion of high voltage lines in Germany

Slide 9

what number routine plants are supplanted by wind factories ? Max 10% !!!

Slide 10

The expense of wind created power in Germany Cost of wind vitality generation in Germany: 2,7 billion € for 26.000 MWh delivered = 103 €/MWh Compare with the expense of atomic force created in France: Baseload  26 7000h/yr  32 5000h/yr  45 3000h/yr  68

Slide 11

Wind vitality creation in France 1500 MW 737 MW Production 2006 : 985 GWh, effectiveness 20% 05 06

Slide 12

Wind vitality in France: a great speculation? For whom? Ashore windmills: year 1 to 10: 82 €/MWh year 10 to 15: 82 €/MWh if under 2400 h/yr : 82 to 68 from 2400 to 2800 h/yr : 82 to 28 from 2800 to 3600 h/yr : 28 above 3600 h/yr Outre-mer: 110 €/Mwh Off-shore: year 1 to 10: 130 €/MWh year 10 to 20: 130 €/MWh if under 2800 h/yr : 130 to 90 from 2800 to 3200 h/yr : 130 to 30 from 3200 àt 3900 h/yr : 30 above 3600 h/yr Tax credit on speculation: 40%
