- Ireland’s data center electricity demand is reportedly increasing by 360% in ten years
- Data centers now account for 23% of the entire country’s electricity consumption
- New data centers can now only be built if certain considerations for power requirements are met
Ireland’s data center electricity consumption has increased 360% in ten years and will now account for 23% of the country’s total electricity demand by 2026.
With total residential consumption at 28% and demand for data centers rising rapidly, 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 a report by Ireland’s Central Statistics Office, which shows data center electricity consumption is up 10% year-on-year from 2024 to 2025, despite a moratorium on new data center grid connections introduced in 2021. In total, the country’s data centers consumed 7,663 GWh last year, despite the rest of the country’s demand increasing by just 2% over the same period.
Ireland struggles with demand for data center power
The 2021 moratorium, imposed by Ireland’s Commission for Regulation of Utilities (CRU), required the national grid operator, EirGrid, to stop processing default power applications for data centers in the Greater Dublin Area. New data centers built following this ruling were therefore required to supply their own energy on site or construct new projects in regions not covered by this restriction.
Consumption since 2021 has risen steadily, prompting the CRU to replace the previous moratorium with the Large Energy User (LEU) connection policy, which subjects new data center projects to a series of measures designed to ease consumption levels on the national grid while creating new sources of energy.
Data centers above 10 MVA are now required to construct on-site flexible power generation that covers 100% of demand, while 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 costs 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, particularly in the US, where working-class communities are challenging new data center projects on an unprecedented scale.
This opposition has been a leading contributor to more than half of US data centers being canceled or delayed, with US citizens citing rising electricity costs, concerns over water usage and fears of AI job replacement as the main reasons for opposition.
