of constructing a 500 MW interconnector to Wales that will allow for importing
and exporting of electricity to and from Great Britain. Effectively, Great Britain
will be Ireland's 'storage' device: excess electricity can be sold when the wind is
blowing and electricity can be imported when it is not. A similar approach to
improve grid stability was carried out in Denmark who installed large interconnectors
to neighbouring Germany, Norway and Sweden (see Table 7).
However, Denmark discovered that they were only using approximately 500 MW
of their wind generation at any time (see Fig. 27). The rest was being exported to
Germany, Norway and Sweden.
