Catalonia aims to increase its presence on the European data center map amid the rapid growth of artificial intelligence, cloud computing, and digital services. The Catalan government has identified 26 potential projects that could be declared strategic or of higher public interest to expedite their approval, totaling an aggregated capacity of around 2,000 MW—far exceeding the current 122 MW installed across the 17 data centers counted by the government.
This initiative positions Catalonia at a significant industrial juncture, but it also sparks an increasingly complex debate: how to attract intensive technological investments without overloading electricity consumption, water demand, and territorial pressure. Most projects are concentrated in southern Catalonia and the Barcelona metropolitan area, while Girona remains outside the new deployment map for now.
A Scale Leap for Southern Europe
The Catalan government has outlined seven territorial hubs to organize the influx of new data centers and channel private promoter interest. The goal is to streamline procedures, coordinate permits, review electricity, fiber optics, and water supply needs, and mediate with municipalities regarding potential urban planning adjustments.
Among the notable projects are two data centers by ADEQUA Real Estate in Santa Bàrbara, Montsià, and Òdena, Anoia, each with 200 MW. Òdena appears as a key point on the new map, with several additional projects planned. Also noteworthy are Ponentia Logistics’ initiatives in l’Hospitalet de l’Infant, l’Espluga de Francolí, and Lleida, which together would total 460 MW.
The city of Barcelona also plays a central role. Five projects are located in areas such as Zona Franca, Sant Martí, La Sagrera, and Sant Andreu. Additionally, six new centers are planned in Cerdanyola del Vallès, within the Parc de l’Alba, one of the most strategic tech spaces due to its proximity to the Alba synchrotron and the local scientific ecosystem of the metropolitan area.
The list of promoters includes both national and international names like Goodman, MERLIN Properties, Quetta Data Centers, and Ark Data Centres. The latter has announced an investment of over €600 million to develop an urban data center near La Maquinista in Barcelona, on a circa 30,000 m² industrial site, with an expected capacity of up to 45 MW IT.
| Zone or Promoter | Main Location | Planned Capacity or Investment | Notable Aspects |
|---|---|---|---|
| ADEQUA Real Estate | Santa Bàrbara and Òdena | 200 MW per center | Two of the largest identified projects |
| Ponentia Logistics | l’Hospitalet de l’Infant, l’Espluga de Francolí, and Lleida | 460 MW combined | Strong presence in the south and inland areas |
| Barcelona city | Zona Franca, Sant Martí, La Sagrera, and Sant Andreu | Details not specified per project | Five urban or metropolitan projects |
| Cerdanyola del Vallès | Parc de l’Alba | Six new centers | Tech hub linked to the scientific environment |
| Ark Data Centres | La Maquinista, Barcelona | Over €600 million and up to 45 MW IT | Urban project announced by the UK operator |
The Cloud Also Has a Postal Code
The economic rationale of the Catalan government is supported by a growing sector consensus: digital services require physical infrastructure. Cloud services, AI platforms, e-commerce, streaming video, digital public services, and enterprise applications don’t operate in a vacuum—they rely on servers housed within buildings connected to electrical grids, fiber optic networks, and cooling systems.
Begoña Villacís, CEO of Spain DC, argued that Catalonia could become one of Southern Europe’s major hubs given its geographic positioning, connectivity, access to renewable energy, and an administration willing to support projects. She also highlighted the importance of technological sovereignty: storing and processing data within European territory has become a strategic issue for companies and administrations.
The rise of artificial intelligence has accelerated this trend. Generative models, inference systems, AI agents, and large-scale data loads demand increasing computational capacity. This demand has placed data centers at the center of industrial policy, not only in Catalonia but across Europe.
The government estimates the sector could generate 2,200 jobs in Catalonia by 2027 and attract cumulative investments of €60 billion. These figures should be viewed as forecasts related to sector development, not guaranteed impacts of projects currently in progress. Experience from other markets shows data centers trigger significant investments in construction, energy, equipment, and operations, but their direct employment post-launch tends to be more limited compared to other labor-intensive industrial activities.
Water, Electricity, and Local Returns: The Pending Debate
The expansion of data centers faces opposition. Environmental groups and some municipalities question whether the economic benefits justify resource consumption. Concerns focus mainly on electricity and water needs for cooling facilities that operate continuously with high redundancy levels.
Agustí Emperador, a data center expert from Ecologistas en Acción, warned SER Catalunya that a 100 MW plant could consume as much electricity as a city the size of L’Hospitalet de Llobregat. He also questions the quality and permanence of employment generated after construction, noting that many permanent roles primarily involve security, maintenance, and auxiliary services.
Water use is another critical point in a region that has experienced severe drought episodes. Despite operators adopting more efficient cooling technologies and water-reducing solutions, the total impact depends on the specific design of each facility, its capacity, local climate, energy source, and cooling system.
The Catalan government asserts that projects seeking simplified approval mechanisms will need to meet European standards and ecological public procurement criteria for data centers, server rooms, and cloud services. Moreover, they must demonstrate strategic contributions to the productive system, academic and research sectors, and talent and innovation generation.
This will be a key factor. Attracting real estate or energy investment alone isn’t enough—the challenge is for data centers to act as catalysts creating a broader technological ecosystem. If AI, cloud, cybersecurity, research, software, and digital industry companies develop around these infrastructures, the impact could be amplified. Conversely, if they merely consume land, energy, and water without local economic integration, social rejection could grow.
Thus, Catalonia faces a strategic decision. It has the connectivity, technological fabric, research centers, universities, and location to aspire to be a significant node in Southern Europe. However, deployment must be carefully planned, transparent, and guided by clear environmental criteria. The data center race won’t be solely about adding megawatts but demonstrating that this power creates technological value, skilled employment, and digital sovereignty without depleting essential resources.
Frequently Asked Questions
How many new data centers does Catalonia aim to promote?
The Catalan government has identified 26 potential data center projects that could be declared strategic or of higher public interest to accelerate their approval. Collectively, these would add up to an capacity close to or exceeding 2,000 MW.
Where will the new data centers be concentrated in Catalonia?
The projects are mainly focused in southern Catalonia and the Barcelona metropolitan area. Key locations include Santa Bàrbara, Òdena, l’Hospitalet de l’Infant, l’Espluga de Francolí, Lleida, Barcelona city, and Cerdanyola del Vallès.
Why do data centers consume such large amounts of electricity and water?
Data centers host servers that run continuously and generate significant heat. They require electricity to power the equipment, backup systems, and networks, along with cooling systems to maintain safe operating temperatures. The cooling technology used influences water consumption—some approaches demand more water than others.
What benefits can a data center bring to a region?
Data centers can attract investment, improve digital infrastructure, boost connectivity, support cloud and AI services, create direct and indirect employment, and foster the arrival of tech companies. The actual impact depends on how well they integrate with the local ecosystem, talent development, and environmental commitments of the project.
