Grid connection. Partial: grid connection agreement for a portion of demand; capacity limited; firm connection conditional on on-site dispatchable generation. "VDC has received and executed a grid connection agreement with EirGrid for a portion of the site’s electricity demand." (EPA P1227-01: Attachment-1-2-Non Technical Summary_25.pdf, p.4)

Not available for this site: measured grid draw (no EPA annual report: only sites with ≥50 MWth of plant file one); rates (no valuation-list entry matched).

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.
