What the planning and licence documents say
Multi-plot campus: generation/cooling figures are for DUB20 (P1240 IE application 2026, 3 ICT buildings, 60 backup gens); grid figures from the 2019 ABP 303938 permission; GFA from 25/60594 ICT facilities; separate gas-turbine energy centre (21/1080, 23/843) permitted but its licence (P1202) withdrawn.
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.
