Red Eléctrica de España released a preliminary report on the country's power system late last month, revealing that for "the first time ever, [wind power] contributed most to the annual electricity demand coverage". According to the figures, wind turbines met 21.1% of electricity demand on the Spanish peninsular, narrowly beating the region's fleet of nuclear reactors, which provided 21% of power.
In total, wind farms are estimated to have generated 53,926 gigawatt hours of electricity, up 12% on 2012, while high levels of rainfall meant hydroelectric power output was 16% higher than the historical average, climbing to 32,205GWh.
