AWS DUB Tallaght Data Center Campus

Status: Fully Operational   |   Location: Airton Road / Belgard Road (Former Jacob's Biscuits Industrial Site), Tallaght, Dublin 24, D24 DA27, Ireland

Project Overview

The AWS DUB Tallaght Data Center Campus is a significant hyperscale digital infrastructure development located at Airton Road and Belgard Road in Tallaght, Dublin 24, Ireland, on the former Jacob’s Biscuits industrial site. Operated by Amazon Web Services (AWS), the campus forms part of the company’s broader infrastructure footprint supporting its AWS Europe (Ireland) region, eu-west-1. The development includes multiple facilities, notably Airton 1 and Airton 2, designed to support enterprise computing, cloud services, data storage, and increasingly demanding artificial intelligence workloads. Its location within South Dublin places it in Ireland’s established technology ecosystem, where reliable digital infrastructure supports businesses and public-sector organizations across Europe and international markets.

A distinctive feature associated with the Tallaght campus is its integration with South Dublin County Council’s Tallaght District Heating Scheme, known as Heatworks. Through this initiative, waste heat recovered from data center operations can be redirected to provide heating for participating public buildings, commercial premises, and affordable residential developments. Rather than allowing all the heat generated by computing equipment to be discharged into the environment, the scheme puts a portion of this thermal energy to productive use. This approach demonstrates how data centers can contribute to local energy systems beyond their core computing function, while potentially reducing reliance on conventional heating sources and supporting municipal decarbonization objectives. The scale of the resulting environmental benefits depends on heat recovery performance, network demand, and the facilities connected to the scheme.

The campus description also identifies Tier III concurrently maintainable design standards, backup power generation, readiness for direct liquid cooling, and diverse dark-fiber connectivity linking into Dublin’s internet exchange ecosystem. These features address key requirements for service continuity, thermal management, and reliable data transmission. Liquid cooling readiness is particularly relevant as high-density computing and AI workloads increase equipment heat loads. Together, the campus’s digital infrastructure and district heating integration illustrate how hyperscale developments can combine cloud service delivery with opportunities for local energy reuse. The Tallaght project therefore holds significance for both Ireland’s cloud infrastructure capacity and the evolving relationship between data centers and urban energy systems.
