However, it isn't an accurate number for what UK offshore wind is now delivering or will deliver in the future. The 2009 UK average offshore CF is reported as about 35% in various articles and there is no reason to think that the 40-45% level will not be a reality soon. Remember, the first round of construction was extremely close to shore and the 3 projects involved in the 2007 stat total the first 212MW of offshore wind and they came online 2003, 2004, and 2005.
How was progress on nuclear power's capacity factor it's first decade of operations?
