Amazon and Microsoft Turn Aragón Into an AI Hub, but Local Residents Sue Authorities

Aragon, a region in northeastern Spain, has become one of the most prominent platforms in Europe's race for AI infrastructure. Technology giants present it as an example of how Europe can rapidly build data centers for cloud services and artificial intelligence. But for local residents, the story looks different: along with multibillion-dollar investments came disputes over land, water, taxes, and who will actually benefit from this boom.

According to current estimates, announced investments by Amazon, Microsoft, and other companies in Aragon have already exceeded €80 billion, roughly $90 billion. The region proved convenient for such construction for several reasons: large undeveloped territories, relatively low electricity prices, a high share of renewable sources, and cheaper labor compared to many Western European countries. For Brussels and major cloud players, this was an almost perfect combination.

Against the backdrop of the EU's plans to at least triple data center capacity over the next five to seven years, Aragon's experience is already being presented as a possible model for other countries. A key tool became the PIGA mechanism, adopted in 2015. It allows regional authorities to accelerate approvals, reduce bureaucratic procedures, and grant projects the status of "public interest."

In practice, this means not only fast permits, but also serious side effects: special tax breaks for developers, the ability to bypass local zoning restrictions, and, if negotiations with landowners fail, compulsory land acquisition. Because of this, several municipalities, including Villamayor de Gállego and Villanueva de Gállego, went to court, challenging the regional government's decisions and the construction's impact on land, water, and local budgets. The largest player in the region now is AWS.

The company launched its first three data centers in Aragon in 2022, and in March 2026 announced it would increase investments to €33.7 billion by 2035. Amazon speaks of tens of thousands of jobs, including through contractors and related businesses, and regional authorities hope to turn Aragon into "Europe's Virginia"—the continent's main data center cluster.

But on the ground, the picture is much less smooth. The first three AWS facilities created approximately 700–950 jobs, and more than three-quarters of them are related to construction, not permanent operations. Meanwhile, local residents are discussing who sold plots of land, who tried to hold out until the end, and why land prices ranged from €2 per square meter in some places to €23 and higher in others.

A separate line of conflict is resources. Data centers for AI require more power and cooling than traditional computing infrastructure. In dry regions of Spain, this automatically raises the question of water, especially when residents already face power outages or restrictions during hot months.

Amazon insists that it uses renewable energy, invests in water projects, and makes cooling as efficient as possible. But some residents doubt that the real burden will be so insignificant, especially since government documents contained requests to increase permitted water consumption due to rising temperatures. Against this backdrop, another question intensifies: if municipalities lose some tax revenue due to exemptions, and the main benefits go to large companies and contractors, why should local communities bear the environmental and social costs?

The main takeaway from Aragon's story is that the race for artificial intelligence is no longer just about chips and models, but about much more tangible things: land, infrastructure, water, permits, and people's trust. For Big Tech, Aragon may indeed look like a textbook case of accelerated construction. But if such projects begin to split small towns, lead to lawsuits, and leave doubts about the fair distribution of benefits, then this case becomes not just about AI-economy success, but about the price that specific territories pay for it.
