According to data published by the Central Statistics Office (CSO), data centers in the country consumed 7,663GWh of power during the year, up ten percent from the year before, which stood at 6,973GWh.
As a result, data centers in Ireland now consume almost as much as every household in the country combined. Ireland has seen a huge proliferation of data centers since 2015, with data center power consumption rising by 518 percent. At present, more than 80 data centers operate in Ireland, with major clusters within the Greater Dublin area.
Dublin has had a de facto moratorium on new data center builds since 2022. The ban was lifted seven months ago by the Commission for Regulation of Utilities (CRU), which replaced it with a new framework requiring operators to provide matching on-site generation and to source at least 80 percent of their annual demand from new, unsubsidized renewable energy projects. The decision followed a CRU decision paper published last February.
