Europe is racing to build sovereign AI capacity — one campus and gigawatt deal at a time.
This is a lean, source-linked pilot: an open ledger of Europe's largest AI / hyperscaler data-center campuses and investment programs. Every record is verified against primary sources. We start with what we can stand behind and add tabs (grid, capital, compute) as verified European data matures — never faking parity with the more mature US dashboard.

How to read this pilot. The ledger mixes three record types: campuses (a sited facility,
sometimes with disclosed MW), capex programs (country-level investment, no single sited MW — most
hyperscaler entries), and one policy program (the EU-wide InvestAI gigafactories initiative).
Because of that, MW figures are not directly comparable and should not be summed — see the caveats in the
open dataset. Known gap: Ireland/Dublin, the
#1 addition for the next version.

European AI data-center campuses & investments
Named builds and power/investment deals across Europe. Each row links to a verified primary source; per-record provenance, capacity type, and confidence travel with the open dataset.
18 source-verified records — campuses, country capex programs, and the EU's InvestAI gigafactories.
The ledger
Sorted by disclosed capacity. Hyperscalers rarely publish site MW, so many rows show a dash (—) for MW with the investment figure in the note.

Do not sum the MW column. Disclosed figures mix ultimate campus targets
(e.g. Sines 1.2 GW vs ~26 MW live today), a wind-supply figure (Meta Odense), and one IT-critical-load
number — and most records disclose no MW at all. Always read capacity alongside status and
capacity type. Full caveats & known gaps are in the dataset.
