Summary
Six-hall, 200 MW data center campus planned by Art Data Centres on about 145 acres beside the Tulla Road on the eastern edge of Ennis, County Clare, near junction 13 of the M18. The national planning board granted permission in April 2024, and in March 2026 the High Court dismissed the last judicial review challenges after years of litigation. Investment is now put at more than EUR 1.6 billion over three phases. Phase 1, with a substation and two data halls, is due for commissioning by the end of 2028; enabling works start with diverting overhead power lines.

Timeline
| Date | Event | Actual or planned | Notes | Sources |
|---|---|---|---|---|
| 2024-04 | Permit approved | Actual | Planning permission from An Bord Pleanála; the 2025 report says permission was first granted in 2022. | Clare FM; Industrial Info Resources; BeBeez International (republishing DCD) |
| 2025-03 | Other | Actual | The court found the judicial review grounds, including those concerning Leisler's bat, lacked merit; the remaining grounds were to be relisted later. | BeBeez International (republishing DCD); Clare FM |
| 2026-03 | Other | Actual | High Court dismissed the remaining judicial review challenges, ending almost six years of legal challenges and clearing the way for enabling works. | Clare FM; Industrial Info Resources |

Power supply
| Type | Description | Sources |
|---|---|---|
| Grid | An 83 MVA connection to the Ennis substation, per Industrial Info. | Industrial Info Resources |
| Wind | Industrial Info says an off-grid substation would be supplied by wind, solar and biogas. | Industrial Info Resources |
| Solar | Solar is one of the sources Industrial Info lists for the off-grid substation. | Industrial Info Resources |
| Other | Biogas is one of the sources Industrial Info lists for the off-grid substation. | Industrial Info Resources |
No construction start had been reported by the sources opened; Clare FM says enabling works can now begin. Investment figures have risen across reports (EUR 1.2 billion in 2025, more than EUR 1.6 billion in 2026). Clare FM and Industrial Info give the campus as 145 acres or 1.3 million sq ft, presenting the two as equivalent although 145 acres is about 6.3 million sq ft; because neither says what the 1.3 million sq ft measures, it is not recorded as floor area. Industrial Info's six halls of slightly more than 33 MW each are not summed. The judicial review was brought by Friends of the Irish Environment, Futureproof Clare and several individuals.
