Title: Wind power variation: a highly variable, unreliable and unpredictable source of energy


1
Wind power variation a highly variable,
unreliableand unpredictable source of energy
  • Facts and statistics
  • from the largest wind generator
  • in Germany E-ON

2
Power variation - per month distributed by E-ON
3
E-ON wind power variation over the year
(theoritical max 7.558 MW)
Installed 7558 MW
Daily max 6234 MW
Daily min 8 MW
Installed capacity 33.200MW including wind 7.558
MW (23) Production 271.300 MWh includ. wind
11.300 MWh (4,16)

Forecasting of wind power is hazardous
January windy season
Max 80
Min 3
Accuracy of prediction from -50 to 100
7
Sensitivity of windmills to grid stability
and Incapacity of the grid to face windmill
output variations
Expansion of wind energy in Germany is not
possible without a European-wide
cooperation, because electrical grids in
neighboring countries are affected by the
instability of wind energy production in
Germany. Example Nov 4th 2006, European-wide
electrical blackout (wind instability involved).
8
Congestion of high voltage lines in Germany
9
How many conventional plants are replaced by wind
mills ?
Max 10 !!!
10
The cost of wind produced electricity in Germany
  • Cost of wind energy production in Germany
  • 2,7 billion for 26.000 MWh produced 103 /MWh
  • Compare with the cost of nuclear power produced
    in France
  • Baseload ? 26
  • 7000h/yr ? 32
  • 5000h/yr ? 45
  • 3000h/yr ? 68

Wind energy in France a good investment?For
whom?
  • On-land windmills
  • year 1 to 10 82 /MWh
  • year 10 to 15 82 /MWh if less than 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 less than 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 investment 40
