⚡ Electricity — is there enough power for AI in the European Union?

Daily observations

Question this table answers: what are the values and dates in each row of "EU27 — day-ahead total load forecast, daily energy in MWh (newest first, last 14 days).…"? (source or retrieval date on each row)

Question this table answers: what are the values and dates in each row of "Breakdown by member-state area — forecast for 2026-09-24 (CET/CEST), MWh"? (source or retrieval date on each row)

Unit: megawatthours (MWh) — the forecast power values (MW) published at 15-, 30- or 60-minute resolution are multiplied by their resolution and summed over the CET/CEST calendar day, then over the 25 member-state areas that publish this item (Ireland and Malta do not publish it under their country-code area; they are counted as areas_not_published, not as missing). "provisional" = fetched on the forecast day itself, or with one or more published areas missing from the sum; refetched daily until final. Machine-readable (with the per-area breakdown and the area list): /eu/api/power_eu.json.

Why this chapter shows "observing", not a judgment

• This edition has no frozen criterion for judging EU grid conditions as good or bad. The Japan edition's power criterion (reserve-margin thresholds) applies to a different indicator published by a different institution, and we do not transplant thresholds across systems.
• The series is a load forecast, not a reserve margin and not measured load. Candidate EU indicators will be studied, defined in a versioned document, and frozen before any badge appears — inventing criteria on the page is prohibited by our editorial rules.
• Until then: numbers, dates, and sources only. Do not infer thresholds we have not written down.
• What this chapter can say: how much electricity the transmission system operators of the 27 member states forecast, one day ahead, for each CET/CEST day (sum of one area per member state, MWh), as published on the ENTSO-E Transparency Platform under CC BY 4.0; which days are final (all 27 areas present, fetched on a later day), which are provisional, and which were backfilled; which 27 areas make up the aggregate (areas_definition in the JSON).
• What this chapter cannot say: how much electricity was actually consumed (actual total load, article 6.1.a, is not published here until ENTSO-E confirms its re-use terms in writing); whether the EU grid is tight or has spare capacity (a load forecast is not a reserve margin; no criterion is frozen); conditions in the United Kingdom, Norway, Switzerland or the Western Balkans (non-member areas are excluded), or what any single member state's grid did (the member-state breakdown is machine-readable only).

Definition (v1.0 draft; frozen with the first observation)

• Which load series, and why a forecast: ENTSO-E lists its day-ahead total load forecast (article 6.1.b) among the data freely re-usable under CC BY 4.0. Its actual total load (6.1.a) is not on that list and remains subject to the platform's general terms and the data owners' rights, so this chapter publishes the forecast, labeled as a forecast in the visible text and in the machine vocabulary (series_kind: forecast, metric id eu.power.eu27_load_forecast). Actual load is added only if ENTSO-E confirms its re-use in writing; it would then be a separate series, never merged with this one.
• Aggregate: the EU27 figure is the simple sum of the forecast over one area per member state (the list is published in the JSON as areas_definition, with verified and available flags from the first retrieval on 2026-09-12). Two of the 27 areas — Ireland (10YIE-1001A00010) and Malta (10Y1001A1001A93C) — return "no matching data" for this item, so the sum covers the 25 published areas; no substitute area is used (the Irish single electricity market area includes Northern Ireland and is therefore not used). Areas of non-member states — including the United Kingdom, Norway, Switzerland and the Western Balkans — are excluded. A day on which any published area is missing is never marked final: it stays provisional and the number and codes of the missing areas are recorded.
• Day boundary and unit: the CET/CEST calendar day, as used by the source; forecast power (MW) × resolution, summed to daily energy (MWh). The platform publishes these series as variable-length blocks (curve type A03: a point is omitted when its value equals the previous one), which are expanded before summing. A day is "final" once fetched on a later CET/CEST day with all 25 published areas present; otherwise "provisional" and refetched.
• Backfill: history retrieved after the series goes live is labeled as retrieved retrospectively (retrieved_retrospectively: true, "backfilled" on the page) and is kept apart from values observed day by day.
