AWS DUB Mulhuddart Data Center Campus

Status: Active Development and Multi-Building Operational Campus Phase   |   Location: Cruiserath Road, Mulhuddart, Dublin 15, D15 A6RX, Ireland

Project Overview

The AWS DUB Mulhuddart Data Center Campus is a major hyperscale digital infrastructure development located along Cruiserath Road in Mulhuddart, Dublin 15, Ireland. Operated by Amazon Web Services (AWS), the campus forms part of the company’s wider infrastructure footprint supporting the AWS Europe (Ireland) region, eu-west-1. The master plan comprises multiple data hall structures, including Mulhuddart 1 through 6 and associated infrastructure nodes, with an estimated 175 MW of gross utility power capacity and 140 MW of critical IT load. This scale positions the development to support growing demand for cloud computing, enterprise digital transformation, and compute-intensive artificial intelligence workloads. Its location in Dublin also places it within one of Europe’s established technology and digital infrastructure markets.

The campus’s stated technical design includes dual-path high-voltage connections to regional electricity infrastructure operated by EirGrid and ESB Networks, alongside modular uninterruptible power supply systems and standby diesel generators intended to support continuity during power interruptions. The development is described as designed to Tier III concurrently maintainable standards, allowing planned maintenance without requiring a complete shutdown of critical systems. Its proposed thermal management features include readiness for direct liquid cooling and closed-loop precision economization, technologies relevant to managing heat from increasingly dense computing workloads. These design elements are particularly important as AI model training and other demanding applications increase requirements for power delivery, cooling performance, and operational resilience.

Connectivity is another stated component of the Mulhuddart development, with dual-diverse dark-fiber ingress intended to link the campus with Dublin’s internet exchange ecosystem and wider international network routes. Such connectivity can support low-latency communications, cloud access, and data exchange for enterprise customers. The project description also references AWS’s broader water and carbon sustainability commitments. However, the campus-specific implementation and performance of these measures have not been independently established here. Overall, the development represents a substantial addition to AWS’s Irish infrastructure strategy, with its ultimate contribution dependent on delivery, commissioning, and verified operational specifications.
