Summary
- Councillors are seeking a national pause on data centre development pending consultation and planning guidance.
- Their concerns include electricity, water, local infrastructure, land use, and cumulative environmental effects.
- The request does not suspend existing permissions or establish a government moratorium.
Kildare County Council members have agreed to ask the Irish Government to introduce a national moratorium on new data centre development until public consultation has been completed and national planning guidance has been prepared.
Councillors intend to write to the Minister for Climate, Energy and the Environment and the Minister for Housing, Local Government and Heritage following a motion considered by the authority.
The request reflects mounting scrutiny of data centre proposals in County Kildare, where large developments have prompted questions about electricity consumption, water availability, planning procedures, and the effects on surrounding communities.
The council’s decision to seek government intervention does not itself impose restrictions on data centre development or suspend planning permissions already granted.
The motion was brought forward by councillors including Noel Connolly, Bill Clear, Mark Leigh, Anne Breen, Aoife Breslin, Angela Feeney, and Rupert Heather.
It calls for national guidance to address the location and scale of developments, their relationship with residential and public infrastructure, and their cumulative effects when several facilities are proposed within the same area.
The councillors also want greater consideration of electricity demand at full operating capacity, peak-period demand management, water infrastructure, waste heat recovery, and the use of alternative cooling technologies.
Those subjects are directly connected to the technical feasibility of large computing facilities, particularly where projects depend on infrastructure serving other commercial and domestic customers.
Two proposed data centre developments near Naas have contributed to local debate. One involves a development associated with Herbata Ltd, which received permission from Kildare County Council but is now subject to an appeal before An Coimisiún Pleanála.
Microsoft has also acquired land at Jigginstown that is zoned for data centre development. Land acquisition and zoning do not establish that a particular facility has obtained every permission or connection necessary for construction and operation.
Local concerns extend beyond individual sites
The councillors’ proposed approach would place greater emphasis on the combined impact of multiple data centres rather than considering each project solely through its individual planning application.
That distinction is relevant where several developments seek electricity capacity from the same transmission or distribution networks.
A facility’s permitted floor area does not indicate the amount of electricity it can actually use. Operational demand depends on installed computing equipment, supporting electrical and cooling systems, and the available network connection.
Several projects may also compete for infrastructure improvements or require reinforcement works whose benefits and costs extend beyond any one development.
Water use is another area where the technical design matters. Evaporative cooling systems can create different requirements from closed-loop or predominantly air-cooled facilities.
Assessment of local water impacts therefore requires information about the proposed cooling architecture, operating conditions, and expected freshwater demand.
The councillors also raised opportunities for heat recovery and district heating, which can be technically attractive where suitable customers are located nearby.
However, the presence of surplus heat does not automatically establish a viable recovery scheme. Its useful application depends on temperature, distribution infrastructure, demand, and commercial arrangements.
The motion seeks to bring those considerations into a clearer national planning framework.
National guidance could help establish common expectations for technical evidence, environmental assessment, and the treatment of competing infrastructure priorities.
Such guidance would remain subject to the Irish Government’s policy decisions and existing legal arrangements.
Noel Connolly has argued that the proposed moratorium should not be interpreted as opposition to technology or investment, but as a means of ensuring that developments are assessed through a more comprehensive planning process.
Opposition to large facilities has also formed part of wider demonstrations in Ireland and across Europe during November.
Those protests and the council’s request add political pressure, but neither changes the legal position of pending applications without further action by the relevant authorities.
The next development will be the government’s response to the councillors’ correspondence and any subsequent decision on national guidance or restrictions.
Until such measures are introduced, the motion remains a request for intervention rather than an enacted moratorium.
