Data Center Atlas
Microsoft Zaragoza (Puerto Venecia) datacenter campus
Site records
Planned Microsoft datacenter campus in the city of Zaragoza beside the Puerto Venecia shopping area, one of three campuses in the PIGA Región MSFT regional plan. The November 2025 plan assigns it 57 hectares and about EUR 1.44 billion, with 50 MW secured for a first phase and up to 300 MW sought later via the Torrero-Valdeconsejo substation. The regional government declared it of general interest in September 2025 and began expropriating about 16.5 hectares of private land. Landowners and the ZeC party contested the project in 2026. Microsoft says only land clearing is authorized until the plan receives final approval.

Landowners facing expropriation say work has begun, which Microsoft disputes, saying only land clearing is permitted before the plan is finally approved. 2026 coverage also mentions a second large data centre planned on rural land at Cartuja Baja in Zaragoza without naming its developer; it is not part of this record. No government primary source was opened; Boletín Oficial de Aragón entries should be added when available.
