National electricity demand in Spain experienced a 1.9% increase in October compared to the same month of the previous year, after accounting for temperature and labor effects. In gross terms, the demand is estimated at 20,135 GWh, which is 1.5% higher than in October 2023.

In the first ten months of 2024, Spain recorded a cumulative demand of 205,703 GWh, which is 0.9% higher than the same period in 2023. After accounting for labor and temperature effects, the demand grew by 1.5% compared to the previous year.

In October, renewable energy generation reached 12,079 GWh, a 15.4% increase compared to October 2023, accounting for 55.9% of total generation. Meanwhile, 78.1% of electricity was produced without emitting equivalent CO2.

The leading source of production for the month was wind energy, with a 26.3% share, followed by nuclear (21.3%), hydroelectric (13.8%), and photovoltaic solar, which accounted for 13.4% of the total. This month, the latter technology saw an increase in production of just over 9% compared to October 2023. Hydroelectric generation also increased, specifically more than double, which can be explained by the rise in rainfall compared to the previous year.

Peninsular Demand Increases by 2%

At the peninsular level, after accounting for labor and temperature effects, demand was 2% higher than in October 2023. In gross terms, this month’s demand was 18,812 GWh, 1.7% higher than the same month last year.

From January to October of this year, peninsular demand reached 192,855 GWh, 1% higher than the demand registered in 2023. Once labor and temperature effects were considered, peninsular demand grew by 1.6% compared to the same period last year.

Peninsular renewable generation in October increased by 14.9% compared to October 2023, reaching 11,875 GWh, which accounted for 58.1% of the total national production structure. Emission-free technologies contributed 81.7% of the total.

The peninsular generation structure for October was also led by wind energy, which was responsible for 27.2% of the total, followed by nuclear with 22.6% and hydroelectric with 14.5%.

Electricity System in the Balearic and Canary Islands

In the Balearic Islands, electricity demand in October was 3.7% higher than in the same month of 2023, after considering labor and temperature effects. Gross demand is estimated at 508,417 MWh, 2.6% higher than October of the previous year. From January to October 2024, gross demand in the Balearics is estimated at 5,197,559 MWh, a 0.3% decrease compared to the same period in 2023.

Regarding generation, the combined cycle was the leading source in the Balearic Islands, accounting for 67.1% of the energy produced. Renewable energy in the Balearics represented 13.7% of the total. Balearic renewable production grew by 13.2% in October compared to the same month last year.

Additionally, during October, the submarine link between the Peninsula and Mallorca contributed to covering 28.5% of the Balearic electricity demand.

In the Canary Islands archipelago, electricity demand fell by 2% compared to the same month of 2023, considering labor and temperature effects. In gross terms, demand was 779,499 MWh, a 3% decrease. From January to October 2024, Canary demand is estimated at 7,318,855 MWh, 0.4% higher than the same period in 2023.

As for electricity generation in the Canary Islands, the combined cycle was also the leading source, accounting for 47.4% of the total. Renewables accounted for 19.8% of production, generating 154,422 MWh, a 73.6% increase compared to October 2023. Wind energy contributed 15.6% of the total, with a 109.9% growth in production compared to October 2023.
