Datacenters now consume 23% of Ireland's electricity, up 10% in 2025 despite a grid connection moratorium.

Ireland's Central Statistics Office reports datacenter electricity use rose to 7,663 GWh in 2025, up from 6,973 GWh in 2024. The sector now accounts for 23% of metered consumption, surpassing urban households (18%) and rural households (9%). Consumption has more than tripled since 2019. A moratorium on new grid connections in Dublin, lifted in December 2025, failed to slow growth. New regulations require datacenter operators seeking connections over 10 MW to provide backup generation or battery systems capable of feeding power back to the grid.

Ireland hosts over 80 datacenters for a population of 5 million. The Trump administration is also working to defuse public opposition to datacenter expansion in the US.

What commenters are saying

The headline word "guzzle" sparked debate over editorial bias versus The Register's long-standing snarky tone. Many commenters defended the language as consistent with the outlet's brand, noting readers choose it for its cynical, humorous perspective. Some argued datacenters have been central to Ireland's tech economy since the 2000s, driven by IDA policy.

Several commenters noted the tension between EU tech sovereignty goals and complaints about American tech dependency. Others pointed to Ireland's renewable energy growth as a mitigating factor. A few criticized the article for lacking scientific or engineering rigor on energy topics.
