The statistics for the first quarter of 2013 show that wind power generation grew by more than 27% to 6.5TWh, from 5.1TWh for the same period last year.
Offshore wind generation expanded from 1.5TWh to 2.5TWh, an increase of 68%, while onshore generation rose 13%, from 3.6TWh to 4.0TWh.
According to the Decc, this growth was primarily due to much increased capacity. Average wind speeds in 2013 Q1 were 4.4m/s, fractionally down from 4.6m/sec in 2012 Q1.
Overall, renewables provided 12.3% of UK power in Q1 2013, compared with 11.3% for the same period in 2012. Wind power is now accounting for 52% of that figure, up from 45%.
