Ireland's data-centre permitting path is grid-first and multi-track. A developer engages the electricity system operators early under the CRU's Large Energy Users Connection Policy (CRU/25/236, December 2025, replacing the 2021 data-centre connection direction), which conditions any new connection offer on dispatchable generation or storage matched to import capacity and on sourcing at least 80 percent of annual demand from new Irish renewable generation within six years of energisation.

Planning permission goes to the local planning authority in the first instance, because the 2018 provision that would route large data centres directly to the national planning body as strategic infrastructure has not been commenced; appeals go to An Coimisiun Pleanala, the renamed An Bord Pleanala. There is no dedicated data-centre EIA class, so environmental impact assessment is triggered through the general screening duty where significant effects are likely.

Standby generation fleets over a combined 50 MW thermal input need an EPA industrial emissions licence, building control runs in parallel with planning, and water and wastewater connections come from Uisce Eireann under a CRU-approved charging policy. Government policy overlays the path without adding consents: the July 2022 Government Statement and the January 2026 Large Energy User Action Plan favour renewable-co-located, grid-efficient projects.

Government Statement on the Role of Data Centres in Ireland's Enterprise Strategy

In force

Government of Ireland policy statement, July 2022

Effective 2022-07-01 · Applies to government

Cross-government principles for assessing data-centre development: preference for projects with strong economic activity, efficient grid use, and co-location with renewable generation. A statement of policy rather than a consent requirement; it is now read alongside the 2025 connection policy and the 2026 Large Energy User Action Plan.

Planning and Development Act 2000

In force

No. 30 of 2000, as amended; strategic infrastructure route at sections 37A to 37J

Applies to both

Ireland's core planning code. Data-centre applications go to the local planning authority in the first instance: the 2018 amendment that would add large data centres (over 10,000 square metres) to the strategic infrastructure classes heard directly by the national planning body has not been commenced as of the date shown. Appeals lie to An Coimisiun Pleanala.

Planning and Development Act 2024

Enacted, not yet in force

No. 34 of 2024, phased commencement

Applies to both

A consolidation and revision of the planning code. The Act was enacted on 17 October 2024. It commences by order, provision by provision, and is in force only in part. An Bord Pleanala continued in being and was renamed An Coimisiun Pleanala. That change took effect on 18 June 2025 under Statutory Instrument No. 256 of 2025, when sections 494 to 531 of Part 17 commenced.

The Irish Statute Book's commencement table, updated to 17 September 2026, shows the development consents provisions in sections 82 to 179 as not yet commenced. It also shows the environmental assessment provisions in sections 208 to 241 as not yet commenced. It shows the repeal of the Planning and Development Act 2000 in section 6 as commenced only in part.

Environmental review

What impact review must precede approval, and who leads it?

Planning and Development Regulations 2001 (EIA screening)

In force

S.I. No. 600 of 2001, Schedule 5, with sections 176A to 176C of the 2000 Act

Effective 2001-12-21 · Applies to both

Schedule 5 has no dedicated data-centre class, so environmental impact assessment is typically required through the sub-threshold screening duty: the planning authority or An Coimisiun Pleanala must screen any development likely to have significant environmental effects, including cumulative effects with grid and onsite-generation works.

Energy and grid

What authorizations govern grid connection and onsite generation?

Electricity Regulation Act 1999

In force

No. 23 of 1999, as amended

Applies to both

The statutory basis for the Commission for Regulation of Utilities and for licensing of generation and supply; the legal foundation under which the CRU issues its connection-policy decisions.

Large Energy User Action Plan (LEAP)

In force

Department of Enterprise, Tourism and Employment, 13 January 2026

Effective 2026-01-13 · Applies to government

A plan-led framework of 17 actions for locating large energy users, including data centres, proposing green energy parks that co-locate demand with renewable generation. Government policy rather than legislation; it operationalises the 2022 statement alongside the CRU's connection policy.

Large Energy Users Connection Policy (CRU/25/236)

In force

CRU/25/236, decision of 12 December 2025

Effective 2025-12-12 · Applies to private

The operative connection policy for data centres and other large energy users. New connection applications require onsite or proximate dispatchable generation or storage matched to import capacity, participation in the Single Electricity Market, and a commitment to source at least 80 percent of annual electricity demand from new Irish renewable generation within six years of energisation. Applications made before the decision continue under the 2021 direction.

Direction on data centre grid connection processing (CRU/21/124)

Superseded

CRU/21/124, direction of November 2021

Effective 2021-11-23 · Applies to private

Directed EirGrid and ESB Networks to apply assessment criteria, including grid constraint at the location, onsite generation, and demand flexibility, before making any data-centre connection offer. Superseded by CRU/25/236 for new applications; pre-existing applications continue to be processed under it.

Water and utilities

Who commits water and sewer service, and under what assessment?

Water Services Acts 2007 to 2022 (Uisce Eireann connections)

In force

Water Services Act 2007; Water Services (No. 2) Act 2013; Water Services (Amendment) Act 2022; CRU-approved connection charging policy

Applies to both

Uisce Eireann is the single national water and wastewater utility. A data centre's water and wastewater connections are applied for under its CRU-approved connection charging policy through the standard non-domestic connection process.

Construction

What codes and permits govern the build itself?

Building Control Acts 1990 and 2007

In force

No. 3 of 1990 and No. 21 of 2007; Building Control (Amendment) Regulations 2014 (S.I. No. 9 of 2014)

Applies to both

Building control runs in parallel with planning: a commencement notice before construction starts, a fire safety certificate, a disability access certificate where applicable, and a certificate of compliance on completion, administered by the local building control authority.

Air and operations

What permits govern backup generators and ongoing emissions?

EPA industrial emissions licensing (First Schedule, Class 2.1)

In force

Environmental Protection Agency Act 1992 (No. 7 of 1992), First Schedule, Class 2.1

Applies to both

Combustion installations with a total rated thermal input of 50 MW or more require an industrial emissions licence from the EPA. A data centre's standby generator fleet is aggregated for the threshold, so large campuses hold IE licences; Amazon Data Services Ireland's licence P1186-01 at Clonshaugh, Dublin is a published example.

The permitting path

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.
