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

Irish datacenters consumed 23% of the country's electricity in 2025, up from 20% in 2023, with consumption increasing by 10% despite a moratorium on new grid connections in Dublin. The energy use has grown dramatically from just 5% in 2015, now exceeding electricity consumed by all urban households combined. New regulations now require datacenter operators to provide backup power systems and feed excess power back to the national grid.
