Planning statistics are compiled by each planning authority on an annual basis for collation and publication on my Department’s website, at the following link:
https://www.gov.ie/en/service/9e4ee-get-planning-statistics/ .
However, the data collected relates to the total number of applications and decisions for all developments that require planning permission, broken down by year and planning authority but does not include specific information on data centres. Such information may be sought directly from the relevant planning authority.
