Installed capacity could nearly increase sixfold in the coming years due to demand from operators, with Madrid rising in the ranks as a European hub

The data center sector in Spain is undergoing an unprecedented transformation that offers the opportunity to strengthen its position on the European stage. According to the “2025 Annual Report on the Data Center Sector in Spain,” projected investment in this infrastructure in our country is expected to reach 66.9 billion euros by 2030.

By the end of 2025, the installed IT capacity in Spanish data centers stood at 439 MW, representing a 24% increase over the previous year. However, this capacity could increase nearly sixfold by 2030 if the forecasts in the report presented on World Data Center Day by Spain DC (the Spanish Data Center Association) and prepared by Pb7 Research prove accurate.

Madrid is home to the majority of current facilities, while Catalonia specializes in colocation services and Aragon is establishing itself in large-scale projects. In terms of economic impact, the sector is expected to generate 16,300 direct and indirect jobs and contribute 7.3 billion euros annually to GDP.

The Spanish market’s ability to meet operators’ demands and adapt to industry trends will be key to continuing to drive an industry that enjoys broad social acceptance due to its impact on the economy and job creation. According to Emilio Díaz, president of Spain DC: "Data centers are no longer 'invisible infrastructure'; they have become a tangible driver of competitiveness, productivity, and digital sovereignty."

Projected trends in the data center market in Spain

Currently, there are nearly 100 data centers in Spain with a capacity of at least 50 kW (the report does not include smaller facilities). By 2025, the installed IT power in commercial data centers reached 439 MW, a 24% increase from 2024. If the current trend continues, Spain could reach 2,537 MW by 2030, which would mean increasing its capacity nearly sixfold in five years.

This growth is a response to rising demand for data centers, driven by the outsourcing of IT services. According to the report, Spanish companies are moving away from their on-premises server rooms to facilities that offer greater guarantees of connectivity, energy efficiency, and regulatory compliance. As a result, by the end of 2025, the capacity of commercial data centers had already surpassed that of corporate data centers.

Geographically, Madrid remains the most significant data center cluster in terms of installed capacity, establishing itself as a Tier 2 European hub. Catalonia stands out as a colocation hub for the Mediterranean region, while Aragon is positioning itself as the leading region for large-scale data centers operated by companies such as Amazon and Microsoft. Projections indicate that the installed IT capacity in the Aragon region will increase tenfold in the coming years, placing it at the forefront of the national sector. These growth prospects underscore the maturity of the Spanish market, which is gaining ground against Europe’s dominant markets (Frankfurt, London, Amsterdam, Paris, and Dublin).

Trends and Challenges in the Data Center Industry

According to the Spain DC report, the evolution of the Spanish data center market is linked to several trends that shape operators’ roadmaps:

• The Rise of Artificial Intelligence: AI workloads require rack densities ranging from 30 to 50 kW, and even higher. This necessitates constant innovation in cooling systems, which is accelerating the transition to direct liquid cooling (DLC) or immersion cooling solutions.
• Promoting digital sovereignty: Given the growing uncertainty in the international geopolitical landscape, Spain has the opportunity to become the computing hub for European AI, hosting and processing critical data on its own territory, with the aim of reducing external dependencies.
• Sustainability requirements: The implementation of the European Union’s Energy Efficiency Directive (EED) requires facilities with a capacity exceeding 500 kW to report on factors such as energy consumption, PUE, and the reuse of waste heat, as key measures for reducing the sector’s environmental impact.
• Energy and water savings: Operators in Spain are increasingly entering into power purchase agreements (PPAs) for green energy and adopting modular designs that optimize the use of water and energy resources.

In addition to addressing these demands, the sector must overcome various challenges in order to meet the projections outlined in the Spain DC report.

First and foremost is access to the power grid: although Spain has the advantage of abundant renewable energy generation—solar and wind—many of the announced projects depend on upgrades to transmission or generation infrastructure. Second, the sector is calling for current regulations to be adapted to the realities of new data center projects. Finally, there is a shortage of skilled labor, particularly professionals with expertise in energy management, advanced cooling systems, and critical operations maintenance.

For these growth forecasts to materialize, the sector’s development will depend not only on investment, but also on the ecosystem’s ability to coordinate, share knowledge, and accelerate the adoption of new technological solutions.

In this context, Data Centre World, which will take place on November 4 and 5 as part of Tech Show Madrid 2026, stands as a key forum for addressing the challenges identified in the Spain DC report in a practical manner.

The event will bring together more than 6,000 professionals and over 160 exhibiting companies, creating a specialized setting for discussing issues such as energy availability, the evolution of cooling systems in light of the rise of artificial intelligence, regulatory adaptation, and the operational sustainability of infrastructure.

Furthermore, its integration into the Tech Show Madrid ecosystem—one of Southern Europe’s leading technology events—and Madrid Tech Week reinforces its role as a hub connecting various technology sectors, providing a comprehensive overview of digital development and the strategic role of data centers.

Beyond analysis, Data Centre World serves as a hub connecting the various players in the sector, facilitating the exchange of knowledge and the creation of opportunities that help consolidate the growth of the Spanish market within the European context. Currently, there are nearly 100 data centers in Spain with a capacity of at least 50 kW (the report does not include smaller facilities).
