Irish Datacenters Consume 23% of Country's Electricity
Ireland's datacenters have increased their electricity consumption by 10% in 2025, accounting for nearly a quarter of the country's metered electricity. This growth outpaces other customers, including urban households, which consume 18% of the country's electricity. The surge in datacenter energy use has raised concerns about the country's energy supply.
Key points
- Datacenters in Ireland consumed 7,663 gigawatt hours (GWh) of electricity in 2025, a 10% increase from 2024.
- Datacenters now account for 23% of Ireland's metered electricity consumption, up from 5% in 2015.
- The growth in datacenter energy use outpaces other customers, including urban households, which consume 18% of the country's electricity.
- The Commission for Regulation of Utilities (CRU) has implemented an effective moratorium on connecting new datacenters to the grid in the Dublin area.
- Analysts warn that the rapid growth in datacenter energy use could strain Ireland's energy supply and lead to increased costs for consumers.
Irish Datacenters Consume 23% of Country's Electricity
According to the Central Statistics Office (CSO), datacenters in Ireland have increased their electricity consumption by 10% in 2025, accounting for nearly a quarter of the country's metered electricity. This growth outpaces other customers, including urban households, which consume 18% of the country's electricity.
The surge in datacenter energy use has raised concerns about the country's energy supply. The Commission for Regulation of Utilities (CRU) has implemented an effective moratorium on connecting new datacenters to the grid in the Dublin area, in an effort to manage the demand.
Analysts warn that the rapid growth in datacenter energy use could strain Ireland's energy supply and lead to increased costs for consumers. The CSO has reported that datacenters used more electricity than urban households, and more than twice the rural-household share of 9%.
The datacenter industry has seen significant growth in recent years, with energy consumption more than doubling between 2015 and 2019, and tripling again between 2019 and 2025.
