5.1 offshore power generation
Over the year, the installed offshore wind power capacity of 68.4
GW would generate 247 TWh of electricity.The estimated annual
offshore wind electricity generation per country is shown in Table 4,
alongside the total electricity consumption in 2006 for comparison.
The capacity factor in Table 3 represents the fraction of time
during which the installed wind farms would have generated the
same amount of energy when always running at full power.The total
aggregated capacity factor of the offshore wind power scenario in
the present study is equal to 41.2%. For comparison: the
aggregated capacity factor of the present installed wind power
capacity in Europe (of which the major part is onshore) is 23%.
