Permitting path

Approvals on record for 1 of 11 path steps; latest: Planning permission (2025-07-31).

Ireland's path runs grid-first: under the CRU's Large Energy Users Connection Policy (CRU/25/236, December 2025, replacing the 2021 data centre connection direction), a new connection offer requires dispatchable generation or storage matched to the facility's import capacity and a commitment to source at least 80 percent of annual demand from new Irish renewable generation within six years of energisation. Planning permission sits with the local authority in the first instance (the 2018 provision routing large data centres directly to the national planning body is not yet commenced), with appeals to An Coimisiun Pleanala, and environmental impact assessment where screening requires it. Uisce Eireann water and wastewater connections, building control certificates, and an EPA industrial emissions licence for standby fleets over 50 MW thermal complete the path.

Steps without a record are shown as not yet requested or not on record: absence of a record here is a records gap, not a finding about the facility. An authority shown for an empty step is the body that would issue it.
