Ireland's data centres draw 7.7 TWh of electricity a year, which places it 5th of the 33 countries this atlas carries a figure for.
That is 24.8% of everything the country generates — well above the 1.2% median across those countries.
Set against 1.2 GW of installed capacity, that implies a 70% load factor.
One metro is tracked here: Dublin, at 1,660 MW and operating.
Its strongest showing anywhere in the atlas is Systems & Facility on the physical basis, at #5 of 54.
It does not register at all on Memory & Storage or Networking.
One supplier is domiciled here, EirGrid, booking roughly $1bn.
About $4bn of AI infrastructure investment has been announced for Ireland, though announced is not built — that figure is graded C.
National context
Grid friction
EirGrid/CRU restrict new Dublin-region connections; data centres reached 23% of metered electricity in 2025.
Where Ireland ranks
The same tables read three ways. A country can lead one basis and be invisible on another, and that gap is the whole point of the atlas.

Revenue is the group or segment figure closest to each tier's perimeter. Segment boundaries differ between issuers, so treat the split as indicative.
