Irish Datacenters Now Consume 23% of the Country's Electricity

Irish datacenters now guzzle 23% of the country's electricity

I report that Irish datacenters now account for 23% of the nation's total electricity consumption, a figure that jumped 10% in 2025 despite a moratorium on new grid connections in Dublin. These massive server farms now use more power than all urban households combined, prompting new regulations requiring operators to provide backup generators and feed power back to the grid when needed.

"Datacenter consumption has grown every single year without exception, more than doubling between 2015 and 2019, and tripling again between 2019 and 2025."
