Irish Datacenters Now Consume 23% of National Electricity
Original: Irish datacenters now guzzle 23% of the country's electricity
Why This Matters
Ireland's case illustrates how AI-driven datacenter growth is straining national energy infrastructure globally.
Ireland's Central Statistics Office reports that datacenter electricity consumption rose 10% in 2025, reaching 7,663 GWh — equivalent to 23% of the country's total metered electricity use, surpassing urban households at 18%.
According to Ireland's Central Statistics Office (CSO), datacenters consumed 7,663 GWh of electricity in 2025, up from 6,973 GWh in 2024 — a 10% increase. Their share of national metered electricity rose to 23%, compared to 20% in 2023 and just 5% in 2015. Datacenters now consume more electricity than urban households (18%) and more than twice that of rural households (9%). CSO statistician Grzegorz Głaczyński noted that datacenter consumption has grown every year without exception, more than doubling between 2015 and 2019, then tripling again by 2025. The growth occurred despite an effective moratorium by the Commission for Regulation of Utilities (CRU) on new grid connections in the Dublin area, which was lifted in December 2025. Under new regulations, operators seeking connections over 10 MW must provide equivalent backup generation or battery storage and supply power back to the national grid when required — a model already in use by Microsoft and Digital Realty. Ireland, home to more than 80 datacenters for a population of just over 5 million, has also seen growing public protests against further datacenter expansion.
