Pipeline · under construction, permitted, proposed
New data centres being built in Ireland
7 data-centre campuses are under construction in Ireland and 9 more are permitted or proposed (StackPath directory, Oct 2026), against 55 operating. EirGrid reported only one new data-centre grid contract under the post-2021 rules by June 2025, and a project takes a median 3 years from application to completion certificate.

The pipeline, stage by stage
16 campuses are in the pipeline (7 under construction, 6 permitted, 3 proposed), against 55 operating; 8 more never got past refusal, withdrawal or expiry.
Each campus gets the status supported by its strongest public evidence, never an operator's announcement. "Under construction" needs a commencement notice on the Building Control system without a completion certificate (or newly mapped buildings with no other record); "permitted" means a live planning permission or EPA licence with no start yet; "proposed" means a decision or appeal is still pending; "lapsed" means every record is lapsed, refused or withdrawn. Status is checked against EPA, valuation and planning records as of 10 Oct 2026.

From permission to power-on
The life of a data-centre project, from planning file to finished building
Planning is quick; building is slow. A council decides in about 2.0 months, an appeal adds 15.2, and the first building is certified complete a median 36.9 months after the application was lodged.
Each bar is the median time for one stage, measured on Irish planning files that mention a data centre (79 council decisions, 16 decided appeals, 35 projects that reached a completion certificate). Medians of different groups do not add up exactly, so the end-to-end line is measured separately; its whisker shows the middle half of projects. 71% of new-build permissions at least two years old had started (39 of 55); the rest are unbuilt or lapsed. Grid offers, EPA licences and energisation dates are not published per project, so they are shown without durations.

How long each step takes (median months)
Once granted, projects start in about 6 months and finish about 18 months later. The delay has moved into planning and appeals.
