Highlights
- These loans will finance works to improve the Valdecañas pumped-storage hydroelectric complex in Cáceres to secure energy supply and to integrate renewables.
- The project has received funding from the Regional Resilience Fund, which was set up by the Spanish Ministry of Economy, Trade and Enterprise to invest a portion of the NextGenerationEU loans, predominantly in environmental and social projects in Spain's autonomous communities.
- This operation also contributes to the EIB Group's strategic priorities - namely climate action and cohesion -, to the objectives of the Spanish Recovery, Transformation and Resilience Plan and the REPowerEU plan, which aims to improve energy security in the European Union.
The European Investment Bank (EIB) has signed two green loans with Iberdrola totalling 108 million - a 50 million loan using own funds and a 58 million loan with funds from the Regional Resilience Fund (FRA). The operation aims to improve the pumping capacity of the Valdecañas hydroelectric complex, which encompasses the Torrejón and the Valdecañas power plants.
The complex will help to secure energy supply and create storage capacity enabling the integration and management of renewable energy. The Valdecañas plant will have a total installed capacity of 225 MW, a 15 MW hybrid battery and 7.5 MWh of stored energy.
Together, the battery and hydroelectric units will make it possible to increase the added pumping capacity to a maximum of 313 MW, and the storage capacity of the Tajo system to 210 GWh. The works to improve pumping capacity will make use of the existing installations in the Valdecañas and Torrejón-Tajo reservoirs - without changes to the levels of operation - and the existing transport networks, thus reducing the impact on the environment.
Once up and running, the complex will help to reduce CO2 emissions. In addition, the improvement works will directly create 165 jobs and a further 500 indirectly, boosting skilled employment. The total investment will take place in a cohesion region, an area where the per capita income is below the EU average. In this way, the project will contribute to climate action and territorial, economic and social cohesion - two of the eight priorities set out in the Group's Strategic Roadmap for the years 2024-2027.
Having received funding from the Regional Resilience Fund, the project is also in line with the objectives of Spain's Recovery, Transformation and Resilience Plan. The Regional Resilience Fund directs funding from the NextGenerationEU programme to boost investment in Spain autonomous communities, predominantly for environmental and social projects. The fund is led by the Ministry of Economy, Trade and Enterprise and is supported by the autonomous communities and cities and the Spanish Federation of Municipalities and Provinces (FEMP), with the EIB Group as a strategic management partner.
This operation is in line with the EIB's action plan to support the REPowerEU initiative to improve energy security in the European Union and to reduce dependence on fossil fuel imports.
How the Valdecañas pumped-storage hydroelectric complex works
Reversible pumping plants, such as those in the Valdecañas hydroelectric complex, make it possible to use and generate electricity quickly, allowing for better management of the consumption and demand curve, and stabilising the electricity grid. The upper reservoir - which feeds the plant - acts like a storage system that is charged with the water's potential energy. Energy can then be stored when excess energy is generated from other non-dispatchable energy sources, and can subsequently be recovered when needed. It operates like a closed circuit between the upper and lower reservoir, which does not just consume water, but also reuses it. This system, which is independent of precipitation and water resources, has a long service life and can provide wide-reaching reinforcement to the electricity grid.
Background information
EIB
The European Investment Bank (ElB) is the long-term lending institution of the European Union, owned by its Member States. Built around eight core priorities, we finance investments that contribute to EU policy objectives by bolstering climate action and the environment, digitalisation and technological innovation, security and defence, cohesion, agriculture and bioeconomy, social infrastructure, high-impact investments outside the European Union, and the capital markets union.
The EIB Group, which also includes the European Investment Fund (EIF), signed nearly 89 billion in new financing for over 900 high-impact projects in 2024, boosting Europe's competitiveness and security.
All projects financed by the EIB Group are in line with the Paris Climate Agreement, as pledged in our Climate Bank Roadmap. Almost 60% of the EIB Group's annual financing supports projects directly contributing to climate change mitigation, adaptation, and a healthier environment.
Fostering market integration and mobilising investment, the Group supported a record of over 100 billion in new investment for Europe's energy security in 2024 and mobilised 110 billion in growth capital for startups, scale-ups and European pioneers. Approximately half of the EIB's financing within the European Union is directed towards cohesion regions, where per capita income is lower than the EU average.
