- Ireland's data center electricity demand reportedly rises 360% in ten years
- Data centers now account for 23% of the entire country's power consumption
- New data centers can now only be constructed if certain power demand considerations are met
Ireland’s data center electricity consumption has risen 360% in ten years, and now accounts for 23% of the entire country’s electricity demand in 2026.
With total residential consumption accounting for 28%, and data center demand rising quickly, it won’t be long before the server farms overtake the consumption of Ireland’s population of just over five million.
These figures come from an Ireland Central Statistics Office report, which shows data center electricity consumption has risen 10% year over year from 2024 to 2025, despite a moratorium on new data center grid connections enacted in 2021. In total, the country’s data centers consumed 7,663 GWh last year, despite the rest of Ireland's demand rising only 2% in the same period.
Ireland battling data center power demand
The 2021 moratorium, put in place by Ireland’s Commission for Regulation of Utilities (CRU), required the national grid operator, EirGrid, to stop processing standard power applications for data centers in the Greater Dublin Area. New data centers built after this ruling were therefore required to supply their own on-site energy or construct new projects in regions not subject to this restriction.
Consumption since 2021 has risen steadily, prompting the CRU to replace the previous moratorium with the Large Energy Users (LEU) Connection Policy, which subjects new data center projects to a set of measures designed to ease the level of consumption on the national grid, while also creating new sources of energy.
Data centers over 10 MVA are now required to construct on-site, flexible power generation that covers 100% of demand, while also sourcing at least 80% of their annual electricity from new, unsubsidized renewable projects within six years.
Ireland has become a hub for big tech. Many companies have built European headquarters in the country, with hyperscalers such as AWS, Google, Meta, and Microsoft building and operating the majority of Ireland’s 89 data centers to power cloud infrastructure and AI models.
As a result of the rapid increase in demand, Ireland now has the highest electricity cost in Europe, with Irish households paying around €480 ($550) more per year compared to the EU average. Higher electricity prices have been a catalyst for data center opposition, especially in the US, where working class communities are challenging new data center projects at an unprecedented scale.
This opposition has been a leading contribution to more than half of US data centers being cancelled or delayed, with US citizens citing rising electricity costs, concerns over water consumption, and fears of AI job replacement as the main causes for opposition.
