Candidates (not yet observed) — added to this chapter once verification completes

• EED data-centre database aggregates (installed IT power, electricity consumption, number of reporting sites) — Only a Qlik dashboard without export or API; no separate licence statement. Added if the Commission publishes a machine-readable dataset (checked 2026-09-03/04).
• Eurostat monthly electricity consumption (nrg_cb_em, EU27) — Reachable (verified 2026-09-04) but not data-centre specific; belongs to the electricity chapter if adopted, so not used here as a substitute.

Method, scope, and why this chapter is not judged

• Observing, not judging: no frozen criterion exists for EU data-centre capacity. Numbers, dates and sources only; do not infer thresholds.
• Cooling degree days: value as published by Eurostat (nrg_chdd_m, EU27_2020, CDD). Eurostat/JRC compute them with their own base temperatures; the U.S. edition uses the CPC 65°F base and the Japan edition 18.3°C — levels are not comparable across editions, only within-edition trends. Eurostat releases the monthly series in batches (the 2026 months appear only when released), so the series is marked "monthly (released in batches)" and is not judged stale.
• Transformer proxy: Eurostat production index of NACE C27.1 (electric motors, generators, transformers, electricity distribution and control apparatus), EU27, seasonally and calendar adjusted, 2021=100. A supply-side proxy: the EU publishes no lead-time statistic. Not comparable in concept with the U.S. order backlog or the Japan production value; points flagged by Eurostat carry the flag.
• EED reporting scheme: Article 12 of Directive (EU) 2023/1791 requires data centres of at least 500 kW IT power to report annually (by 15 May) to a European database. The public output is a dashboard without export or API, so this chapter keeps a ledger of the legal basis, publications and deadlines and reproduces no dashboard figures. Aggregates quoted in the press are not verifiable against a primary machine-readable source and are not shown.
• No siting series: the EU publishes no monthly statistic equivalent to the U.S. Census "Data center" construction category; the candidates list records what would be needed.
• Boundaries: grid load belongs to the electricity chapter; rules belong to the regulation chapter; drought and water to the planned water chapter.
• Proxies, not data-centre electricity consumption (ruling 2026-09-04): cooling degree days measure the climate demand for cooling and the C27.1 index measures the output of the electrical-equipment industry. Neither is the electricity consumption of data centres, which the EU does not publish in machine-readable form.
• What this chapter can say: how much cooling the EU27 climate demanded, month by month, as Eurostat computes it (a driver of data-centre cooling load); whether EU27 output of the industry that makes transformers, generators and switchgear is rising or falling (a supply-side signal for grid connection and data-centre build-out); what the EU data-centre reporting scheme (EED Art. 12) legally requires, when it reports, and where the Commission publishes.
• What this chapter cannot say: how much electricity EU data centres consume (no machine-readable EU statistic exists; dashboard figures are not reproduced); how many data centres are being built or where (no EU construction or siting statistic equivalent to the U.S. Census category); whether any level is good or bad, or how the EU compares with the U.S. or Japan on these proxies (different bases and concepts).
