What the planning and licence documents say
EdgeConneX Facility Campus west of the R120 (Ballymakaily): EDCDUB04 and EDCDUB05 (4 data halls) plus energy centre ESSDUB97 under EPA licence P1204-01 (2025), and DUB06 (2 further halls, granted on appeal ABP-317802, Jul 2025) as the third and final phase; earlier ACP 300752 relates to the existing DUB01-03 campus east of the R120.
Every value is quoted from the document and page cited; the quote was checked against that page's text. "Derived" means the reader worked it out from stated figures (shown in the quote). Planning and licence figures are design or permitted values, not measured use; values derived from an EPA annual environmental report (AER), mostly water, are reported use for that year. The note under each quote gives the scope and whether a demand figure is a maximum or an average.
