The Department of Energy and Climate Change (DECC) said the improvement was down to increased capacity and higher wind speeds during the period.
Additionally, offshore electricity production rose by 146%. Onshore and offshore wind energy combined produced 1.6TWh.
Electricity from gas-fired power stations fell by 21.1% thanks to higher gas prices.
Speaking about the figures, RenewableUK's director of economics and markets, Dr Gordon Edge, said: "While the amount of power generated by wind turbines is of course dependent on the strength of the wind at any given time, these figures help to demonstrate the increasing importance of wind generation as part of our electricity supply."
