Taiwan's data centres draw 3 TWh of electricity a year, which places it 15th of the 33 countries this atlas carries a figure for.
That is 1.0% of everything the country generates — around the 1.2% median across those countries.
Set against 0.4 GW of installed capacity, that implies a 90% load factor.
One metro is tracked here: Hsinchu, at 260 MW and operating.
Its strongest showing anywhere in the atlas is Silicon on the control basis, at #1 of 10.
17 suppliers are domiciled here, booking roughly $589bn between them; the largest is Foxconn (Hon Hai).
Its single strongest grip on the buildout is Foundry, where firms domiciled here hold 76% of global supply in a sub-layer weighted 0.98 for how hard it is to substitute.
About $4bn of AI infrastructure investment has been announced for Taiwan, though announced is not built — that figure is graded C.
National context
Where Taiwan 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.

Supply positions
Share of each global sub-layer held by firms domiciled here, and how hard that sub-layer would be to substitute. Those two multiplied are what the control basis ranks on.

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