As heavy winds lashed Spain on Saturday evening wind parks generated 9,862 megawatts of power which translated to 40.8 percent of total consumption due to low demand during the Easter holiday weekend, AEE said.
Between Friday and Sunday wind power accounted for an average of 28 percent of all electricity demand in Spain, which is a leading world producer of such energy, a statement from the association said.
The record for power generated by Spain's wind parks was set on March 4 at 10,032 megawatts, but as it was a regular working day this accounted for less percentage demand.
Spain's wind power generation equalled that of hydropower for the first time in 2007.
In July the government approved legislation that will allow offshore wind parks to be set up along the nation's vast coastline in an effort to boost the use of renewable energy sources.
While more expensive than land-based wind farms, offshore wind parks can take advantage of stronger, steadier coastal breezes.
