Dubbed “MSFT Region,” the ambitious plan involves building three interconnected data center campuses across La Muela, Villamayor de Gállego, and Zaragoza. Think of it as a digital trifecta, strategically positioned and linked by a high-speed fiber optic network.
Octavio López, Aragón’s Minister of Housing, Logistics, and Territorial Cohesion, signed off on the “Plan of General Interest of Aragón” (PIGA), setting the stage for construction to begin. This initial approval is a crucial step, but the project still faces a 30-day public review period before it’s fully cleared for takeoff.
The scale of this undertaking is impressive. The three campuses will collectively span over 700 acres. La Muela takes the crown as the largest site, followed by Villamayor de Gállego and Zaragoza. Beyond the physical buildings, Microsoft is laying down nearly 150 miles of fiber optic cable and over 115 miles of conduit, ensuring lightning-fast connectivity.
Beyond the sheer size, the economic impact is staggering. Construction alone is expected to require between 1,000 and 2,000 workers per phase. Once operational, the data centers will create around 900 permanent jobs. The projected building costs? A cool €5.3 billion ($6.17 billion).
A Microsoft spokesperson emphasized the company’s commitment to the region: “The initial approval of the PIGA represents a significant step in the development of Microsoft’s data center project in Aragón…This project reaffirms Microsoft’s commitment to driving innovation, economic growth, supporting the Aragónese technology industry, and creating jobs in the region.”
Microsoft’s investment in Aragón isn’t happening in a vacuum. The company already has a growing data center presence in the region around Zaragoza, and this latest expansion builds upon previous commitments. In fact, Microsoft first announced plans for a cloud region in Aragón in October 2023 and later pledged to invest another €6.69 billion ($7.16 billion) in new data centers.
This is part of a broader strategy. Last year, Microsoft committed to investing $2.1 billion in cloud and AI infrastructure across Spain. Further solidifying their commitment, in March 2025, Microsoft earmarked an additional €2.9 billion ($3 billion) for a new data center campus in Zaragoza, near Puerto Venecia.
Microsoft also operates a cloud region in Madrid, which opened in June 2024 , demonstrating the company’s significant and expanding footprint in the country.
Competition Heats Up
Microsoft isn’t the only cloud giant eyeing Spain. Amazon’s AWS launched a cloud region in Aragón back in November 2022 , with facilities reportedly near Zaragoza in the Huesca Logistics Platform, Villanueva de Gállego, and El Burgo de Ebro. The race to dominate the Spanish cloud market is officially on.
The approval of Microsoft’s data center hubs signals a major turning point for Spain’s digital infrastructure. As AI and cloud computing become increasingly critical, expect to see even more investment and competition in this rapidly growing market. The future of Spain’s tech landscape is looking brighter than ever, powered by data and driven by innovation.
