Summary
- Kildare County Council voted 22–11, with seven abstentions, against two motions challenging data centre zoning.
- The affected Jigginstown and Maudlins land is designated specifically for data centre development under the Naas Local Area Plan.
- Microsoft has been developing an early-stage campus proposal near Jigginstown but has not submitted a planning application.
Kildare County Council has rejected two attempts to reopen land zoning that specifically supports data centre development in Naas, keeping a potential Microsoft campus area within a planning designation created before Ireland’s current argument over electricity demand intensified.
Councillors voted 22 against the motions, 11 in favour, with seven abstentions. The proposals were brought by Independent Ireland councillor Bill Clear and Sinn Féin councillor Noel Connolly and were considered together at the council meeting on 28 September.
The motions sought to review or remove zoning provisions covering land in the Jigginstown and Maudlins areas. The sites are designated for data centre use under the Naas Local Area Plan 2021–2027.
Microsoft confirmed in 2023 that it was developing plans for a data centre campus near Jigginstown. No planning application has yet been lodged, leaving the zoning decision several steps removed from approval for an actual facility.
Zoning survives, but the infrastructure test remains
The council vote preserves the planning status of the land rather than approving a data centre. Any future scheme would still have to pass through detailed planning, environmental assessment, grid-connection, and infrastructure processes.
That difference has become particularly important in Ireland. Data centre proposals now attract scrutiny not only over land use but over whether additional large electricity consumers can be connected without undermining system security, climate commitments, or other economic development.
Kildare sits close to the established Dublin data centre market but also illustrates the geographic pressure for development to spread beyond the most constrained parts of the capital. A site may offer land and proximity to fibre routes while still depending on transmission and distribution investment to support a hyperscale load.
The local campaign against the zoning has focused on environmental, energy, noise, and air-quality concerns. Protesters gathered outside the council offices while the motions were being considered, and campaigners have said they intend to continue opposing data centre-specific zoning.
Councillors opposing the motions were not voting on a Microsoft planning application, because none currently exists. The immediate decision was whether an existing local-area-plan designation should be reopened before a detailed development had been submitted.
That timing puts the planning system in an awkward position. Removing zoning can pre-empt a project before its engineering and environmental case is available for assessment, while leaving it untouched can be interpreted locally as an endorsement of development that may ultimately require very large infrastructure commitments.
The vote also comes days after an Irish parliamentary committee heard competing arguments over a data centre moratorium. That discussion included the balance between investment, power-system constraints, national climate targets, and a substantial development pipeline.
Those national questions are increasingly surfacing in municipal planning. Grid access is determined through electricity-system processes, but councils must deal with the local land, traffic, noise, air, water, visual, and community consequences of projects whose energy requirements can be comparable with heavy industry.
For developers, the Naas decision retains a degree of planning certainty around where a proposal may be considered. It does not provide certainty over electricity, planning approval, construction, or customer demand.
Microsoft’s next move will therefore be more consequential than the survival of the zoning itself. A formal application would put actual building scale, power systems, backup generation, cooling design, and environmental effects into the public record, allowing the argument to move from the principle of data centre development to the engineering of a specific campus.
