Domestic electricity demand fell by 3.4% in February with respect to the same month last year, after adjusting for the effects of temperature and working patterns. In absolute terms, total demand was estimated at 19,871 GWh, marking a 2.3% decrease compared to 2024, a leap year with an additional day in February. Excluding the extra day effect, gross demand would have increased by 1.4%.

In the first two months of 2025, gross electricity demand reached 42,779 GWh, 0.2% higher than in the same period of 2024.

This February, renewables generated 11,543 GWh, accounting for 54.1% of the total. 76.3% of the electricity produced was generated without emitting any CO2 equivalent.

The leading generation source for the month was nuclear, with a 22.1% share, followed by hydropower, which grew by 41.6% to reach a 20.2% share. Next in the mix were wind power (17.3%), solar photovoltaic (14%)—which grew by 14.3%—and combined cycle, responsible for 13.8% of total production.

Additionally, a total of 237 GWh was allocated to storage facilities, while 1,214 GWh was scheduled for export to neighbouring countries. Therefore, this allowed for greater utilisation of the energy generated from renewable technologies. 

The electricity system in the Balearic and Canary Islands

In the Balearic Islands, electricity demand in February was 0.5% higher than in the same month in 2024, after adjusting for the effects of working patterns and temperatures. Gross demand was estimated at 422,796 MWh, a 3.1% increase from the previous year. 

In the first two months of 2025, electricity demand in the Balearic Islands totalled 881,943 MWh, 2.6% higher than in the same period of 2024. 

In terms of electricity generation, the combined cycle—which accounted for 61% of the energy produced in the Balearic Islands—was the leading source this month. Meanwhile, renewable energy generation in the Balearic Islands accounted for 12.7% of the total. Renewable generation in the Balearic Islands grew by 15.4% in January compared to the same month last year. 

Additionally, this February, the submarine link between the Peninsula and Mallorca helped cover 21.6% of the Balearic Islands' electricity demand. 

On the other hand, electricity demand in the Canary Islands decreased by 3.2% compared to the same month in 2024, takingo into account the effects of working patterns and temperatures. Gross demand totalled 677,632 MWh, marking a 2.9% decrease from February 2024, which had 29 days on the calendar.

In the first two months of the year, total electricity demand in the Canary Islands reached 1,433,986 MWh, 0.9% lower than in the same period of 2024. 

In terms of electricity generation in the Canary Islands, the combined cycle was also the leading source in February—with 39.2% of the total. Renewables accounted for 21% of electricity generation, producing 142,420 MWh, a 3.7% increase compared to the same month last year. Wind power contributed 16.1% of total electricity generation this month.
