Big Tech Is Building Huge Data Centers in One of Spain's Driest Regions

Keypoints:

• Spain's Aragon region has 27 planned data center projects covering around 7 square miles.
• Most projects involve American companies, including Amazon and Microsoft.
• Amazon Web Services expects its planned facilities to create 6,200 permanent jobs.
• Residents worry about water shortages, electricity demand and the loss of farmland.
• Companies promise to rely mainly on renewable energy, but environmental concerns remain.

The race to build AI infrastructure is changing the landscape of northeastern Spain. In Aragon, one of the country's driest regions, technology companies are planning a network of enormous data centers even as local communities face repeated droughts and growing pressure on water supplies.

According to official documents cited by NPR on October 22, the region has 27 planned data center projects, mostly involving American companies. Together, they would cover around 7 square miles of land. 

Amazon Web Services (AWS) plans to invest nearly $40 billion in its Aragon projects, while Microsoft and investment firm Blackstone are also expanding their presence in the region. AWS says its planned facilities will create 6,200 permanent jobs.

Aragon's regional government is encouraging the investment through tax incentives and faster approval procedures. Projects given special status can receive compulsory land acquisition powers, bypass local mayors' vetoes and face a public objection period of just 23 working days. Officials hope the investment will establish Aragon as a major European hub for the AI economy. However, Spain's national government is also working on stricter rules for data centers because of concerns about water and electricity consumption. 

For residents, the economic promise comes with difficult questions. Data centers need enormous amounts of electricity to run servers and process AI workloads. They also require cooling systems that can consume substantial amounts of water, particularly during hot weather.

Farmer Julio Enfedaque fears the expansion could put additional pressure on irrigation supplies. His region has already experienced severe dry spells, and water available for farming was cut by two-thirds during a recent drought. Residents are also concerned about construction noise, constant lighting and agricultural land being converted into industrial sites. 

Technology companies say renewable energy will power most of their facilities. AWS has also pledged investment in water infrastructure and more efficient farming practices. However, questions remain about how much water individual facilities will consume. The company has declined to publish water-use figures for each site, according to NPR.

The debate reflects a wider challenge facing the AI industry. Countries need computing infrastructure to support growing demand for AI services, but building it requires land, energy and water. Spain's sunny climate and renewable energy potential make it attractive to technology companies, yet electricity-grid capacity and water scarcity remain significant constraints. 

Aragon is betting that data centers will bring jobs and long-term economic growth. Local residents, meanwhile, want assurances that the AI boom will not come at the expense of their farms, water supplies and communities. The question is whether the region can attract billions in technology investment while protecting the resources its existing economy depends on.
