Renewables	Amazon CPPAs with Irish wind farms (115 MW Galway, 91 MW Donegal, 23 MW Cork); rooftop PV	"These projects are all financed by the applicant via corporate power purchase agreement" ACP 310729 inspector report, p.20 Corporate portfolio, not site-specific.

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.
