Filed projects cover about half of the €70bn announced for Aragon's data centres

Fundación Basilio Paraíso puts announced data-centre investment in Aragon at about €70bn, of which more than €33.4bn sits in official administrative files. Local firms planning staff and hosting around the build-out have a firmer base in the filed figure.

What happened

  • Amazon said in March it would invest €33.7bn in Spain through 2035 around its AWS Europe region in Aragon, €18bn more than the €15.7bn it had announced before.
  • Microsoft is building three campuses at La Muela, Villamayor de Gállego and Zaragoza on a €5.356bn budget, linked by about 240km of fibre.
  • Aragon's government gave the Microsoft sites strategic status under its PIGA planning framework, and Microsoft says initial approval speeds the paperwork.
  • The study expects the operating campuses to add about €1.15bn a year to Aragon's economy and sustain about 3,217 permanent jobs over their life.

Why it matters

  • decision Local suppliers and landlords who size bids to the €70bn headline are counting projects the study itself left out of its impact model.
  • contradiction A hiring plan built on Amazon's job estimate would overstate the permanent workforce the study expects to remain once the campuses are running.
  • capability Aragonese firms get cloud and AI capacity close by, and the study ties the region's lasting gain partly to whether those firms buy it.

The study used the filed figure for its own model. Fundación Basilio Paraíso, which did the work with Microsoft's collaboration [1], took projects with official administrative files as its base when it calculated the likely economic impact on Aragon [2]. Microsoft is also one of the companies building there [8]. The filed base is about 48% of the announced total [15]. As much as €36.6bn of the headline sits outside it [16].

Amazon's programme is one of the largest in the count [14], and its own estimates extend beyond Aragon. Amazon expects the programme to add €31.7bn to Spanish GDP through 2035, of which €18.5bn is in Aragon [5], about 58% [17]. The other €13.2bn or so goes elsewhere in Spain [18].

The two job figures in the record measure different things. Amazon's 13,400 is one company's annual average over an investment programme that runs to 2035, and it includes indirect and induced employment [6][3]. The study's 3,217 is the permanent operating workforce of the facilities it modelled [11]. The first is about 4.2 times the second [19]. I'd expect competition for local workers to peak in the construction years, which the study dates from 2024 to 2033 [10]. Amazon's planned server manufacturing, testing and repair sites add a separate pool of hardware jobs, about 1,800 when fully operational by the company's estimate [7].

CEO Today's report on the study warns that the longer-term value "will depend on what remains after the construction phase" [13]. On money, the study's own figures answer that worry. It puts construction at more than €8bn of direct and indirect value across 2024 to 2033 [10], a little over €0.8bn a year on average [20]. Its estimate for each year of operation is higher than that [11]. Payroll does worse on the same figures, since operations sustain the smaller job count [11]. The Foundation names three conditions for a broader technology economy: local supplier development, skills training and wider adoption of AI by Aragonese businesses [12].

The evidence on power and land is thinnest. The study as reported does not address grid capacity or land prices, so any claim about competition for either needs evidence from elsewhere. The only planning input in the reporting is the strategic status already given to Microsoft's sites [9]. For local firms the nearer change is supply. Amazon's AWS region and Microsoft's three campuses, built for cloud services and AI, are both in the region [3][8].

What to watch

  • Whether more of the €70bn reaches official administrative files, the step that moves a project into the study's own impact base.
  • Final approval of Microsoft's PIGA after the initial approval and strategic status Aragon has granted.
  • Any published grid-capacity or land-use assessment for the Aragon campuses, the evidence needed to judge competition for power and sites.
