Knowledge of the amplitude of the fluctuation in wind power generation is essential to determining the properties of the required backup power source.

First plots are shown given the raw wind production data plotted as averages over 1 day for 3 years. Afterwards plots are shown to evaluate the amplitude of the fluctuations.

The next plots evaluate the amplitude of the fluctuations by averaging the wind generation data for period of 1 hour, 1 day and 3 days, then looking at the maximum, minimum and mean wind power during a month interval for these short term averages.
