INSTALLED CAPACITY 2024
Installed capacity
Information based on provisional data as of January 2025
As of 31 December 2024, the Spanish electricity system's installed capacity, including both the peninsular and non-peninsular systems, as well as generation and storage capacity, had increased by 4.6% compared to the previous year, reaching an all-time high with an installed power capacity of 132,343 MW.
Installed capacity from renewable energy generation in the Spanish electricity system increased by 4.7 GW in 2021, by 6.3 GW in 2022, and by 6.8 GW in 2023. In 2024, installed capacity from renewable energy generation experienced the highest increase recorded to date, with an additional 7.3 GW, bringing the total installed capacity from renewable energy generation sources in the Spanish electricity system to 85.1 GW. The integration of this new renewable capacity, mostly wind and power solar photovoltaic, represented a significant boost to the energy transition and the fulfilment of the integration roadmap set out in Spain’s National Energy and Climate Plan (NECP), with a 2030 deadline.
As for the Spanish electricity system’s installed storage capacity in 2024, it stands at 3,356 MW, of which 3,331 MW correspond to pumped storage and 25 MW to batteries, which have increased by 1.0% compared to 2023.
The power generation fleet of the peninsular electricity system is also becoming increasingly cleaner, as there was an 9.4% increase in installed capacity from renewable energy generation in 2024 compared to the previous year.
The increase in installed wind power capacity in 2024 was 4.2%, making it the second-largest generation source in the ranking of installed capacity in the peninsular system. With a total of 31,452 MW, wind power represents 24.8% of the total installed capacity in the peninsular electricity system.
Over the course of 2024, installed solar photovoltaic power capacity experienced the greatest increase within the peninsular electricity system, adding almost 6,000 MW to the power generation fleet. In 2024, solar photovoltaic became the leading technology in the peninsular electricity system in terms of installed capacity for the first time in history, reaching 31,719 MW and surpassing wind power, which accounted for 25.1% of the total installed capacity in the peninsular system (compared to 21.3% in 2023).
Conversely, renewable energy generation in the peninsular system decreased by 3.5% in 2024, primarily due to the final decommissioning of the 1,403 MW Puentes García Rodríguez thermal power plant in La Coruña, following the official shutdown certification.
In non-peninsular systems, there was an increase of 1.1% in installed capacity by the end of 2024. This increase is due to the 0.8% growth in installed wind power capacity and especially, the 10.5% increase in solar photovoltaic compared to 2023.
In the Canary Islands, the installed capacity from renewable energy generation rose from 899 MW to 964 MW over the last year, representing an 7.1% increase. This growth means that installed capacity from renewable sources in the Canary Islands accounted for 28.7% of the total Canary Islands power generation fleet by the end of 2024. Specifically, the increase in installed capacity was due to a rise in wind power, with a growth of 0.8%, and solar photovoltaic with 25.3%.
Installed solar photovoltaic capacity in the Canary Islands grew from 235 MW in 2023 to 294 MW in 2024, keeping its position as the sixth largest source of generation in the Canary Islands mix. At 31 December 2024, solar photovoltaic capacity represents 8.8% of the total installed capacity in the island system (7.1% in 2023).

The most relevant aspects of the installed capacity by autonomous communities in 2024 include:
- Andalusia is the second autonomous community in terms of installed capacity from renewable energy generation in Spain, with a total of 13,613 MW of green power, surpassed only by Castile and Leon. In 2024, it was the autonomous community that installed the most MW, adding 2,253 MW of new solar photovoltaic capacity and 23 MW of wind power. It thus increased its renewable energy generation capacity by 20.1% compared to 2023. As a result, 63.5% of Andalusia’s installed capability is renewable.
- In Aragon, installed capacity from renewable energy generation grew by 7.1% with the commissioning of 240 MW of photovoltaic energy and 412 MW of wind power. It is the second region with the highest installed wind power capacity (5,659 MW), representing 45.4% of the region’s total installed capacity.
- Cantabria has 798 MW of installed capacity, with pumped storage technology leading the energy mix at 45.2% of the total. Renewable technologies account for 19.7% of the region's capacity.
- In Castile–La Mancha, installed capacity from renewable energy generation increased by 8.8% in 2024. It ranks second in renewable energy generation capacity share in Spain, with 84.9%. This renewable growth in 2024 was driven by the installation of 123 MW of wind power and 958 MW of solar photovoltaic capacity.
