In 2024, wind power was once again, for the second consecutive year and the fourth time in history, the leading source of national generation, with a 23.2% share in the generation mix. Additionally, wind power was the technology with the highest share in the national electricity generation structure for seven months in 2024. The maximum share for the year was recorded in February, with 32.0%.

Annual share of wind power generation in total generation

In terms of wind power generation by autonomous community, Castile and Leon continues to be the community that produced the most electricity from wind energy in 2024, with 12,515 GWh, which represents 20.5% of all wind power generated in Spain.

In 2024, Aragon was the second Spanish autonomous community in terms of wind power electricity generation with 11,458 GWh, 18.8% of wind power generation nationwide. It also ranks first in terms of the highest share of wind power electricity generation in its energy mix with 52.3%.

Navarre was the second Spanish autonomous community with the highest share of wind power generation in its energy mix, with 50.5% of this region's electricity generation mix (41.0% in 2023).

In the national electricity system, the highest monthly wind power generation in 2024 was achieved in February. This month also registered the highest proportion in the coverage of generation, with a share of 32.0% of national generation. In addition, February, June, and September recorded the highest monthly wind electricity generation to date since statistical records began for each of these months.

The historical record for national wind electricity generation was broken on Thursday, 21 November, reaching 441,022 MWh, a 2.5% increase compared to the previous historical record set on Wednesday, 8 December, 2021.

In the Canary Islands, annual wind power generation achieved a historical record with 1,408,742 MWh, a 2.6% increase compared to the previous record from 2022. Additionally, August 2024 saw the highest monthly electricity generation from wind power in the Canary Islands with 210,632 MWh, 0.5% higher than the previous record achieved in July 2023.

Wind power generation, monthly peaks, and share of total generation

The high variability of the wind means that the contribution of wind power generation to hourly coverage fluctuates considerably. Therefore, during the year there were hours with a percentage of hourly coverage of less than 1%, with the minimum value occurring on 5 February between 14 and 15 hours. However, national wind power electricity generation also reached high values, with the highest annual share of the electricity generation structure occurring on Wednesday, 22 November, between 0 and 1 hours, with 59.7%.

The wind producible index in 2024 reached a value of 0.94, lower than the average of the last ten years. During this year, the highest rates were recorded in September and October, with values amounting to 1.21 and 1.14, respectively.
