Iberian Energy Storage Research Center in Extremadura: key insights for the sector

Key data

The Iberian Research Center on Energy Storage is moving forward with a new modification of its founding agreement. The second Amendment, signed on April 8, 2026 and published in the BOE on April 27, 2026, updates the commitments between CIEMAT, the Junta de Extremadura and the Fundecyt Foundation-Scientific and Technological Park of Extremadura for the construction, equipment and commissioning of the center.

For companies in the energy sector, this is not just institutional news: it is a signal that an applied research infrastructure in energy storage—a strategic technology for the energy transition—is taking concrete shape in Extremadura, with guaranteed European financing.

What does this regulation establish?

The General Secretariat for Research publishes the second Amendment to the original agreement signed between the four parties. This modification updates or expands the initial commitments in one of these three areas:

• Financing: Adjustment or expansion of the economic commitments of each party for project execution.
• Timelines: Review of execution schedules for the construction and equipment of the center.
• Specific actions: Modification or incorporation of specific actions provided for in the original agreement.

The project is framed within the Recovery, Transformation and Resilience Plan, which implies compliance with the execution and justification requirements of Next Generation EU funds: spending traceability, compliance with European timelines and application of the principle of do no significant harm to the environment (DNSH).

The center has an Iberian vocation and is oriented towards applied research in energy storage technologies, a strategic sector for the energy transition in Spain and the European Union.

Economic and operational impact

The direct impact of this amendment is institutional and scientific, but it has relevant economic and operational consequences for the private energy sector:

• R&D&i infrastructure available: The commissioning of the center will create specialized infrastructure in energy storage accessible for public-private collaborations. Companies in the sector will be able to access applied research capabilities without needing to develop them internally.
• Next Generation EU funds as leverage: European financing guarantees project execution, but also imposes strict timelines and justification requirements. Companies collaborating with the center will need to adapt to these compliance frameworks.
• Scientific-technological ecosystem in Extremadura: The consolidation of the center strengthens the region as a pole of attraction for investment in energy and technology, with potential impact on the location of industrial and R&D&i projects.
• Public-private collaboration in energy R&D&i: The center's model opens the door to joint research agreements, technology licenses and innovation projects with mixed financing.

Who does it affect?

• Energy sector companies interested in storage technologies (batteries, hydrogen, thermal storage, etc.) seeking R&D&i collaboration.
• Scientific institutions and universities that can establish research agreements with the center.
• Technology and engineering companies supplying equipment or services for energy research infrastructure.
• Investors and funds with interest in the energy innovation ecosystem in Extremadura and the Iberian Peninsula.
• Public administrations in Extremadura involved in the execution and justification of Next Generation EU funds associated with the project.
• Researchers and research groups in the field of energy storage seeking infrastructure and financing.

Practical example

A Spanish company manufacturing energy storage systems by batteries wants to develop a new generation of cells with higher energy density, but does not have its own laboratory for pilot-scale testing.

With the Iberian Research Center on Energy Storage operational in Extremadura, this company can explore a collaboration agreement with CIEMAT and the Fundecyt Foundation to access the center's facilities, co-finance the research with its own funds and take advantage of the public-private collaboration framework that the agreement establishes.

This type of agreement would allow it to access advanced research infrastructure without the capital investment that building it would entail, and potentially benefit from R&D&i calls linked to the center's ecosystem, financed with European funds.

What should companies do now?

1. Identify if your activity is compatible with the center: If you operate in energy storage, renewable energy, battery technology, hydrogen or related sectors, this center is an opportunity for direct collaboration. Evaluate whether your company has R&D&i lines that could benefit from the infrastructure.
2. Contact the Fundecyt Foundation and CIEMAT: They are the managing entities of the center's scientific ecosystem. Start conversations to explore possible collaboration agreements, joint projects or access to facilities.
3. Review R&D&i calls linked to Next Generation EU: The Recovery, Transformation and Resilience Plan framework includes aid calls for energy innovation projects. Consult the Ministry of Science, Innovation and Universities to identify compatible financing lines.
4. Prepare the compliance structure for European funds: If your company participates in projects linked to Next Generation EU, ensure you have spending traceability systems and justification documentation adapted to European requirements.
5. Monitor the project's evolution: The second Amendment indicates that the project is in an active development phase. Following BOE publications and communications from the Junta de Extremadura will allow you to identify when the center is operational and ready to receive external collaborations.
