Key points
- Data center electricity use rose to 7,663 GWh in 2025.
- Consumption increased by 360% from 2015 to 2025.
- Q4 2025 consumption surged 584% from Q1 2015.
- Ireland hosts around 89 data centers, mainly in Dublin.
Data Center Consumption Surge
In 2025, data centers were responsible for 23% of Ireland's total electricity consumption, consuming 7,663 GWh, up from 6,973 GWh in 2024. This 10% growth in a single year contrasts sharply with a mere 2% increase for the rest of the country.
Long-Term Growth Trends
Over the last decade, the consumption of electricity by data centers in Ireland has skyrocketed. The figure for 2025 is a dramatic 360% increase from 5% reported in 2015. This steep rise is especially evident in quarterly figures, revealing a 584% growth from Q1 2015's 291 GWh to Q4 2025's 1,991 GWh.
Impact on Local Communities
The rising electricity consumption from data centers has sparked a significant debate regarding their impact on local communities. Critics argue that the high demand is contributing to increased electricity bills for residents, particularly as server farms are essential to the rapid growth of AI technologies.
Current Regulatory Measures
In response to the escalating electricity demand from these data centers, the Commission for Regulation of Utilities (CRU) implemented a moratorium on new data centers in November 2021 to prevent potential blackouts. This regulation reflects ongoing concerns about the stability of the energy grid amid the data center boom.
The Role of Hyperscalers
A substantial portion of Ireland's data centers is occupied by major hyperscalers such as Microsoft, AWS, Google, and Meta, which use these facilities primarily for cloud infrastructure and applications related to AI technologies. The structure of these server farms highlights the country's strategic position in the global tech landscape.
