Generation

In 2023, wind power was the first largest source of national generation, with a 23.5 % share in the generation mix. Wind was the technology with the highest share in the national production structure for eight months in 2023. The maximum share for the year was recorded in November, with 32.4 %.

In terms of wind power generation by autonomous community, Castile and Leon continues to be the community that has produced the most electricity from wind power in 2023, with 13,553 GWh, which represents 21.7 % of all wind power generated in Spain. In addition, Castile and Leon was the Spanish second region with the highest proportion of wind power generation in its energy mix, with 51.7 % of this region's production mix (59.6 % in 2022).

In 2023, Aragon was the second Spanish region in terms of wind power production with 12,004 GWh and occupies the first position in terms of the highest proportion of wind power generation in its energy mix with 54.0 %.

In the national electricity system, the highest monthly wind power generation in 2023 was achieved in January and November, also registering the highest participation in the coverage of generation in November, with a share of 32.4 % of national generation. In addition, in August, monthly wind power generation reached the highest value for this month recorded to date since statistical series have been available, with 4,267 GWh.

On Monday, 26 October 2023, daily wind power production set a new record high in terms of its share in the national generation structure with a value of 53.8 %, and on 9 March 2023, from 21:00 to 22:00, there was an all-time high in wind power generation, with 21,122 MWh.

In the peninsular electricity system, on Thursday, 9 March at 20:35, a new record of instantaneous wind power generation was reached, with a value of 20,897 MWh. This new maximum represents an increase of 2.8 % with respect to the previous maximum of 20,330 MW, recorded on Monday, 21 November 2022 at 18:37.

July 2023 saw the highest monthly wind production in the Canary Islands with 210 GWh, 14 % higher than the previous record, achieved in August 2022. In addition, on 14 July 2023, the historical daily and hourly production records were surpassed, with 10,197 MWh for daily production, and 480.6 MWh between 20:00 and 21:00 for hourly production.

National 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 have been hours whose percentage of hourly coverage has been less than 1 %, with the minimum value occurring on 12 June between 10:00 and 11:00. However, national wind power production has also set new record highs, reaching the highest historical share in the production mix, with a value of 61.25 % on Wednesday, 25 October, between 04:00 and 05:00.

In 2022, the wind producible index reached a value of 0.97, which is very similar to the average of the last ten years. During this year, the highest rates were recorded in October and November, with values exceeding 1.2 and 1.1, respectively.
