between North and South (e.g. Denmark vs. France).
Besides the fact that the main wind direction is from
West to East, especially the low pressure weather
systems with strong wind speeds also move mainly
from West to East. This leads to a correlation between
England and Germany of about 0.50, in contrast to
only 0.18 between France and Germany.
Figure 13.6 shows the correlation of the local wind
power time series with either the simulated offshore
wind power (figure to the left) or onshore wind power
(figure to the right) in Northern Europe, as assumed
in the 2030 scenario of offshore grid. It reflects that
most of the offshore capacities in the 2030 scenario
OffshoreGrid – Final Report
are concentrated in the Southern North Sea. In contrast
to this, the onshore wind power in the scenario is
more or less evenly distributed over Northern Europe.
In total, wind energy is clearly concentrated in the
North. This concentration will pose considerable
challenges regarding the power flows in the future
European electricity grid.
To conclude, the analysis shows that grid interconnections
between regions of low weather correlation can
significantly reduce the variability of European wind
power production. The North-South direction is the
most interesting from correlation point of view.
