In April, renewable energy contributed 64.3% to Spain's power mix.
In April, renewables contributed 64.3% to Spain’s electricity generation, according to provisional data from the grid operator Red Electrica de España (REE). Renewables generated 12,955 GWh, with wind power leading at 21.6%, followed by solar photovoltaic at 20.1% and hydroelectric at 19.4%.
April saw record figures, such as renewable power generation reaching 80.7% of total output between 12:00 and 13:00 on April 16, and solar PV achieving an hourly record of 61% on April 21. Energy storage systems integrated 990 GWh of renewable energy during the month.
When adjusted for temperature and calendar effects, national demand decreased by 2.1% compared to April 2024. Overall, consumption was 18,655 GWh, down 3.3% year-on-year, partly due to Easter's timing. Daily demand dropped significantly on April 28 by 40.9% compared to the same day in 2024, and on April 29, it fell by 12.7% year-on-year. These declines coincided with a widespread blackout affecting mainland Spain and Portugal on April 28, with power mostly restored the next day. The cause of the outage is still under investigation.
From January to April, cumulative demand reached 83,686 GWh, a 1.2% increase over the same period in 2024, or 0.5% higher when adjusted.
In the Balearic Islands, adjusted demand rose by 0.7% year-on-year, with renewables providing 18.1% of electricity and combined cycle plants being the primary source. The interconnection with the mainland met 19.9% of local demand.
In the Canary Islands, demand decreased by 1.7% year-on-year, with renewables accounting for 21.1% of generation, primarily from wind power, which contributed 15.1%.
