The average wind speed at the site during the year was 8.6 m/s and power exports amounted to 145,201 MWh, giving a capacity factor of 27.6%. Capacity factors of individual turbines ranged from 14% to 36%. The long term capacity factor is estimated to be 30.1%. Problems with one of the three cables that connect the wind farm to the shore led to some restriction of the output during the year. The Scroby Sands annual report illustrates the importance of careful scheduling of maintenance activities: there were 116 days when access to the wind farm was not possible. The wind turbines are accessed using specially adapted "transfer vessels" and these cannot operate in wave heights of more than about 1.5 metres.
