Wind Conditions

 

Since 2003, the environmental conditions with regard to the use of wind energy have been scientifically recorded and evaluated at three Fino measuring stations funded by the Federal Government. The acronym Fino stands for: "Research platforms in the North Sea and Baltic Sea". Of the three Fino stations, Fino 1 and Fino 3 are located in the North Sea and Fino 2 in the Baltic Sea. Fino 1 is in the immediate vicinity of the alpha ventus test field, Fino 3 is about 140 km northeast of Fino 1 and close to the Dan Tysk offshore wind farm. The evaluations of the Fino measuring stations confirm the significantly better offshore wind conditions, even in comparison with very good coastal locations.

 

The following figure shows the average wind speed of the past years at a height of 90 metres above the North Sea (Fino 1, Fino 3) and at a height of 92 metres above the Baltic Sea (Fino 2). At the editorial deadline not all results for 2018 of the measuring stations Fino 1 and Fino 2 were available, therefore these results can only be evaluated as preliminary. As arithmetical, long-term mean values of the wind speed at a height of 90 metres and 92 metres at the stations in the comparison period 2011 to 2018, respectively, were calculated: Fino 1: 9.0 m / s, Fino 2: 9.3 m / s, Fino 3: 9.6 m / s. These data are reference values, as there was no filtering of disturbances by mast influences or other impairments.
It should also be noted for these representations that no complete data series are available due to measurement technology failures.

The following figure shows the Weibull distributions of wind speeds at the measurement sites Fino 1 and Fino 3 at a height of 90 meters. No comparable data was available for Fino 2 in 2018. For comparison, the measurement data obtained over many years at the three measuring stations are shown in the next figure.

The wind directions prevailing for many years at a height of 90 metres at Fino 1 (following figure) are characterised by inflows from the southwest. The long-term wind direction distribution, measured on Fino 2, about 440 km east of Fino 1 in the Baltic Sea as the crow flies, is shown in the following figure. Here, too, southwesterly winds dominate the wind regime. Fino 3, on the other hand, also has larger shares in the southwest to northwest range (225° - 315°), see the last figure.
