DayOne Aragon AI Data Center Campus: Technical Specs & Infrastructure

Status: Announced / Under Development   |   Location: Ctra. de Quinto de Ebro a Gandesa (A-221), 50790 Escatrón, Zaragoza, Spain

Project Overview

The DayOne Aragon AI Data Center Campus is a 300 MW hyperscale artificial intelligence infrastructure development located in Escatrón, in Zaragoza province, Spain, and developed by Singapore-headquartered DayOne in partnership with Spanish energy group Ignis. Representing an estimated investment exceeding €3 billion, approximately $3.2 billion, the project is designed to support the rapidly growing demand for large-scale AI computing, high-performance computing, cloud infrastructure, and other power-intensive digital workloads. The campus benefits from its strategic co-location near Ignis’s existing and planned power generation assets, enabling the development of an integrated energy strategy tailored to the substantial electricity requirements of hyperscale AI infrastructure. A key element of the project is its hybrid energy supply model, which combines natural gas peaking capabilities with locally generated solar and wind power. This configuration is intended to provide a resilient and flexible electricity supply while increasing the contribution of renewable energy to data center operations. The combination of multiple generation sources can also help manage fluctuations in renewable output and support the continuous power requirements of high-density computing systems. The campus’s 300 MW planned capacity provides significant room for deploying dense GPU clusters and advanced AI computing infrastructure as demand for accelerated computing continues to expand across Europe. Its location in Zaragoza province also places the development within a growing renewable energy and industrial ecosystem, creating opportunities to align large-scale digital infrastructure with regional energy resources. By integrating hyperscale computing capacity with dedicated and diversified power generation, the DayOne Aragon campus represents an emerging model for AI data center development in Europe, where access to reliable, scalable, and increasingly renewable electricity is becoming a critical factor in the deployment of next-generation computing infrastructure.
