In October, renewable energy generation in Spain rose by 15.4% compared to the same period last year, comprising 55.9% of the monthly electricity mix. Wind energy led production, accounting for 26.3% of total output. Nationwide electricity demand increased by 1.9% year-on-year when adjusted for temperature and work patterns, reaching 20,135 GWh in gross terms, a 1.5% rise over October 2023.
For the year to date, Spain recorded a cumulative demand of 205,703 GWh, a 0.9% increase from 2023, or 1.5% when accounting for external factors. Renewables produced 12,079 GWh in October, while emission-free sources generated 78.1% of Spain's electricity.
The monthly generation structure was led by wind (26.3%), nuclear (21.3%), hydropower (13.8%), and solar photovoltaic (13.4%), with solar output growing by over 9% year-on-year. Hydropower generation more than doubled due to increased rainfall.
On the Spanish mainland, adjusted demand rose by 2% compared to October 2023, totaling 18,812 GWh in gross terms, or 1.7% above the previous year. From January to October, mainland demand reached 192,855 GWh, up 1% year-on-year and 1.6% with adjustments.
In the Balearic Islands, demand grew by 3.7% year-on-year when adjusted, with gross demand at 508,417 MWh. Combined cycle plants provided 67.1% of Balearic electricity, while renewables contributed 13.7%. The submarine link between the Peninsula and Mallorca covered 28.5% of the islands' October demand.
Conversely, the Canary Islands experienced a 2% decline in adjusted electricity demand, with gross demand down by 3% to 779,499 MWh. Renewables showed strong growth in the region, comprising 19.8% of production, with wind energy production increasing by 109.9%.
Spain's energy landscape is steadily shifting toward renewable sources, with notable contributions from wind, hydropower, and solar photovoltaic, supporting its long-term goal for a cleaner energy mix.
