Spain faces an industrial decision that cannot be resolved with slogans. Data centers will put pressure on energy, water, the electric grid, and territory. Denying this would be naive. But making them a homogeneous threat would also be naive.
Not all data centers are the same. A poorly located installation with inefficient cooling, weak energy integration, and limited local return has a different impact than a project designed with strict efficiency criteria, competitive renewable supply, proper electrical connection, acoustic control, heat recovery, and clear water use restrictions.
The question should no longer be “yes or no to data centers.” The mature question is: which centers, where, with what energy, with what water, with what cooling, with what network connection, and with what industrial return for the territory.
Digital infrastructure can no longer be planned in isolation
For years, data centers have been discussed as if they were purely technological issues. Servers, connectivity, the cloud, artificial intelligence, storage, and processing. That view falls short. A modern data center is also an energy infrastructure, a territorial infrastructure, and in many cases, a piece of industrial policy.
Digitalization requires computing capacity. Artificial intelligence even more so. The cloud, video, backups, financial services, electronic administration, cybersecurity, online commerce, and business connectivity depend on data centers. But that dependence has a clear consequence: the more digital the economy, the more physical its foundation becomes.
Data doesn’t float in the air. They are processed in servers that consume electricity, need cooling, occupy land, connect to fiber networks, and depend on substations, permits, civil works, security, maintenance, and specialized staff.
That’s why planning cannot be done in compartments. Energy, water, grid, technology, urban planning, environment, and productive development must be analyzed together. If each area makes decisions separately, the result will be a sum of frictions: blocked projects, facing neighbors, stressed networks, endless permits, and poorly explained industrial opportunities.
Technical requirements, not a free pass
Spain does not need a free pass for data centers. It needs technical standards and demands. That distinction is important.
A serious policy does not consist of approving any project promising investment, nor rejecting it because it consumes resources. It involves conditioning approval based on measurable criteria: proper location, real connection capacity, responsible water use, energy efficiency, integration with renewables, advanced cooling systems, acoustic assessments, organized construction plans, network impact, benefits to the environment, qualified employment, possible use of residual heat, and transparency.
Public debate is often oversimplified. Some portray data centers as an automatic guarantee of wealth. Others treat them as a burden that adds no value. Both positions are limited.
A data center can be an opportunity if well-designed and integrated into a territorial strategy. It can attract investment, strengthen connectivity, improve electrical infrastructure, promote technical employment, generate auxiliary activity, and help more companies operate nearby. But it can also become a problem if it arrives unplanned, competes for scarce resources, leaves little local value, and presents itself as inevitable.
The key difference lies in the conditions set.
Energy, water, and territory: the new critical triangle
The debate will increasingly focus on: energy, water, and territory.
Energy will determine which projects are viable and which are not. It’s not enough to say renewable supply will be available. It’s essential to know how they connect, what capacity exists, what reinforcements the grid requires, what impact they have on other industrial uses, and what stability can be guaranteed.
Water will be another sensitive issue. Not all cooling systems consume the same amount, and not all territories have the same water availability. Some projects may need to be discarded based on location, others will have to adjust their design, and some can operate with strict criteria if technology and environment allow.
Finally, territory will be the space where everything is concrete. A data center cannot be imposed as a closed box landing in a municipality. It must explain what it contributes, what it demands, what risks it manages, and how it integrates with the local economy.
There will also be a broader issue beyond data centers. In upcoming years, territorial planning must incorporate mining, energy-intensive industry, renewables, energy storage, data centers, network infrastructures, and new activities linked to digital transition. All will compete for land, permits, connection, and social legitimacy.
Poor coordination will turn each project into a local battle. Spain will repeat a familiar pattern: turning an industrial opportunity into a territorial conflict.
Industrial return must be part of the permit
A data center should not be evaluated solely based on initial investment. What it leaves behind is also crucial.
Industrial return can take various forms: technical employment, local hiring, training, partnerships with universities or vocational centers, infrastructure improvements, attraction of tech companies, nearby cloud services, connectivity for local businesses, or collaboration with other energy uses.
Not all projects will contribute equally, but all should explain their contribution. An installation consuming local resources must justify the value it returns— not just as a slogan, but through concrete commitments.
This is especially important because digital infrastructure tends to concentrate. If Spain aims to capitalize on the demand for AI-related computing, cloud, and data capacity, it should do more than just offer available land and competitive energy. It should build around industrial capabilities, talent, suppliers, managed services, cybersecurity, connectivity, operations, and technical expertise.
That’s the difference between attracting investment and fostering sustainable development.
Plan carefully or discuss later
The worst way to approach this debate is to wait for each project to come with details, hectares, megawatts, and local opposition. By then, the conversation will be contaminated. Some will talk about jobs. Others about water. Others about grid. Others about speculation. And almost all will arrive late.
Planning should be proactive: identifying suitable zones, consumption limits, water criteria, electrical capacity, fiber corridors, potential heat uses, acoustic standards, efficiency benchmarks, and minimum returns. This would provide security for investors, administrations, and citizens.
It would also help distinguish good projects from bad ones. Because the core issue is: the debate isn’t about being for or against data centers. It’s about having the technical and political capacity to tell the difference.
Spain has the potential to position itself favorably in the European digital economy. It has connectivity, renewables, land, geographic location, and a growing tech market. But that advantage can be wasted if speed is mistaken for lack of conditions.
Digital infrastructure will increasingly be energy infrastructure. Without proper conditioning, it will generate resistance where there could be development.
The challenge isn’t to open the door to all projects, nor to close it out of fear. The challenge is to demand that arriving data centers fit within the territory, respect its limits, and help build a digital economy with more of its own industrial capacity.
Frequently Asked Questions
Do data centers consume a lot of energy?
Yes, they are energy-intensive infrastructures. Their location, grid connection, energy efficiency, and access to renewable supply must be assessed rigorously.
Do all data centers have the same water impact?
No. It depends on the cooling system, climate, technical design, and location. That’s why water use must be a central criterion for each project.
Should Spain reject new data centers?
Not necessarily. It should require well-located, efficient, properly connected projects with industrial return for the territory.
What does it mean that digital infrastructure will become energy infrastructure?
That digital services will increasingly depend on available energy, robust electrical networks, storage, renewables, and territorial planning.
What is the risk of poor planning?
Turning an industrial opportunity into a series of local conflicts over land, water, energy, and the lack of visible benefits for the community.
