unboxing Dublin’s data centre landscape

Ireland – and Dublin in particular – has become one of Europe’s leading data centre hubs, hosting an estimated 127 active or planned data centre buildings and campuses – a staggering number given Ireland’s relatively small population (Data Center Map, 2026). The number of data centres in Ireland per capita is 10 times higher than the European average (Sustainable Energy Authority of Ireland, 2025).

This growth is closely tied to Ireland’s broader technology sector, which plays a critical role in the national economy and positions the country as one of Europe’s leading digital hubs. Since the 1990s, Ireland has pursued a deliberate strategy to attract foreign direct investment, anchored by a low corporate tax rate and a suite of incentives for research and development. These policies, combined with EU market access and a highly educated, English-speaking workforce, have attracted major multinational firms across software, cloud computing, social media, and financial technology (IIEA, 2025).

Today, 16 of the world’s 20 largest tech firms have a significant presence in Ireland (IDA Ireland, 2025). In 2022, the Irish ICT sector represented 34.8% of the gross value added - by far the highest share in the EU (European Commission, 2025). Data centres themselves are a significant contributor, estimated to have added €7.3 billion to the Irish economy (Trinity Centre for Digital Business and Analytics, 2025), with further growth expected as demand for cloud computing and artificial intelligence continues to expand. On a European level, there is strong momentum to expand the bloc’s AI capacity through the expansion of digital infrastructure (Politico, 2026).

However, the benefits of the digital economy have been concentrated – both geographically, in and around Dublin, and structurally, among a relatively small number of large firms. In 2024, almost half of the Corporation Tax collected by the State was paid by three multinational – two of which are tech firms (RTE, 2026).

nearly 90% of Dublin’s data centres are in economically deprived areas.

To better understand the placement of data centres in relation to economic deprivation, TASC examined the locations of 97 active or planned data centre buildings across the greater Dublin area alongside measures of local socio-economic conditions. Using the Pobal HP Deprivation Index - which classifies small areas based on indicators such as employment, education, and household composition - we find that 84 out of 97 data centre buildings are located in areas classified as marginally below average, disadvantaged, or very disadvantaged.

This concentration reveals a clear spatial inequality: the infrastructure underpinning the global digital economy is being embedded in communities that are already economically marginalised. While these developments are often framed as engines of local growth, their geographic distribution suggests a different reality - one where the burdens and benefits of the digital economy are unevenly shared.

The business logic behind this pattern is unsurprising. Economically-deprived areas offer relatively affordable land, making them attractive for large-scale, land-intensive developments. They are also typically located on the periphery of the city, where access to power and fibre infrastructure can be secured without the constraints of dense urban environments.

Supporters of data centres often argue that these facilities will bring jobs to local communities - jobs that could help address persistently higher unemployment rates (Amazon, 2023). There is some truth to this during the construction phase, which can generate short-term employment. However, Ireland’s construction sector is already experiencing labour shortages, meaning that new data centre projects may simply intensify competition for workers, drive up costs, and crowd out other forms of development, particularly housing (Houses of the Oireachtas, 2025).

Once operational, data centres generate relatively few permanent jobs. Despite their enormous physical footprint, they are highly automated environments, typically employing only a few dozen staff (Wall Street Journal, 2025). Many of these roles require specialised technical skills or advanced education, limiting their accessibility to residents in disadvantaged areas (IEEE, 2026).

At the same time, the massive quantities of electricity they consume have system-wide implications. In 2024, data centres accounted for 22% of Ireland’s total electricity demand, according to the Central Statistics Office, and this share is projected to rise significantly in the coming decade (CSO, 2025). In Dublin and neighbouring County Meath - where Meta operates large facilities - data centres already consume around 50% of metered electricity (RTE, 2026). Recent decisions by the Commission for Regulation of Utilities to permit new grid connections are likely to intensify this demand. While these rules require data centres to source 80% of their electricity from renewables and eventually supply power back into the grid, they also allow facilities to run entirely on fossil fuels for their first six years and permit the remaining 20% of energy to come from gas or diesel. Alongside requirements for on-site backup generators - typically powered by fossil fuels - this framework risks locking in higher emissions and further straining an already constrained electricity system (RTE, 2026).
