Installed capacity

Wind energy represents a quarter of the total installed national generation capacity.

Wind power was once again the second largest renewable energy generation source in Spain, with an installed capacity of 33,274 MW, which increased by 3.6% in 2025 compared to 2024, totalling an additional 1,146 MW installed across the country. At 31 December 2025, wind power accounted for almost a quarter of the national installed capacity, ranking just behind photovoltaic solar in terms of its share in the installed capacity structure. When self-consumption is taken into account, installed wind power capacity shows little variation.

Annual evolution of installed wind power capacity

By autonomous community, Castilla y León continues to be the leader in installed wind power capacity with a total of 7,751 MW, representing 23.3% of the total national installed wind power capacity. Moreover, Castilla y León was the autonomous community that experienced the greatest increase in installed wind power capacity in 2025, with 458 MW more than the previous year. Aragón is in second place with 6,061 MW, 18.2% of the total.

Wind power is the leading technology in the installed capacity structure of four autonomous communities, starting with Navarra, where it accounted for 44.4%, Aragón with 44.1%, Castilla y León with 42.8%, and Galicia with 41.7%. These communities account for 58.5% of all installed wind power in Spain.
