Timeline
| Date | Event | Actual or planned | Notes | Sources |
|---|---|---|---|---|
| 2025-03-13 | Announced | Actual | Azora | |
| 2025-03-13 | Other | Actual | The Government of Aragon declared the project of general interest (DIGA); published in the regional gazette on 3 April 2025. | Gobierno de Aragón; Azora |
| 2026-02-21 | Other | Actual | Tillion Aragón filed the Plan de Interés General de Aragón for initial approval. | Gobierno de Aragón |
| 2026-07 | Other | Actual | El Español reported the regional plan approved in July; the regional page lists an initial-approval order dated 24 June and no final approval. Public information on the plan and its environmental documents followed. | El Español; Gobierno de Aragón |

Power supply
| Type | Description | Sources |
|---|---|---|
| Grid | Planned 400 kV connection to Red Eléctrica's Peñaflor substation with 66 kV lines and on-site substations. | Gobierno de Aragón; Azora |
| Other | Azora says the campus will run fully on renewable energy through self-consumption or long-term power purchase agreements; El Español reported a plot added to the plan for power supply. | Azora; El Español |
The regional plan page shows a last-updated date of 7 July 2026, used as its published date. The date of the initial-approval order is ambiguous on that page (shown as 24 June with a 2025 order code, before the February 2026 filing), so the approval milestone follows El Español's July report. Microsoft separately plans a campus in the same municipality (microsoft-aragon-villamayor-de-gallego); this is a different project.

Evidence
Sources are linked, not redistributed; each keeps its own terms. An archived copy is a lookup for the Wayback Machine capture nearest the retrieval date and may be unavailable or differ from what was reviewed. Each hash states what it covers; imported factual records are not publisher-page captures.
