Near-primary sourcePress release only2026-06-10
Deal structureAI data-center campus development / power-backed site partnership
GeographyEscatron, Zaragoza, Aragon, Spain
Infrastructure layersData centers + power infrastructure + construction / EPC + cooling
Disclosed scaleMore than EUR3B / about $3.47B investment for a 300 MW AI and HPC data-center campus in Escatron, near Zaragoza, supported by a reported 444 MW grid connection, renewable energy supply and backup from Ignis gas generation

Why it matters

The strategic read

Puts DayOne's post-Series-C European expansion into a named Southern Europe AI campus instead of a generic market list. Ignis brings the scarce asset: land, grid connection, renewable supply and gas-backed reliability in Aragon, where power access and fiber are turning Spain into a live hyperscale AI siting market. The receipt also shows DayOne converting its new $4.5B growth capital into a concrete Europe buildout lane.

Source-supported terms

What was disclosed

  1. 01

    DCD reported on June 10, 2026 that DayOne revealed details of its first data center in Spain, a 300 MW campus in the Aragon region.

  2. 02

    Renewable-energy firm Ignis is developing the data center in Escatron, near Zaragoza.

  3. 03

    The project is expected to cost more than EUR3B, or about $3.47B, and aims to become one of the largest AI campuses in Southern Europe.

  4. 04

    DayOne is expected to operate the campus, which will sit on a plot of roughly 900 hectares.

  5. 05

    The development is designed to scale progressively to 300 MW and support high-density AI and high-performance-computing workloads.

  6. 06

    Heraldo de Aragon reported on June 7, 2026 that DayOne allied with Ignis to secure a 444 MW grid connection, green-energy supply and support from Ignis' Peaker Escatron combined-cycle gas plant.

  7. 07

    Heraldo reported the data center will be built near the thermal plant on industrial land owned by Ignis and is expected to support more than 250 workers.

  8. 08

    DCD noted that DayOne announced its $4.5B Series C last week and named Spain as a key growth market, but had not previously identified the specific site.

  9. 09

    The project reinforces Aragon as an AI infrastructure region because of available land, renewable energy access, electrical capacity and fiber connections.
