Data Status and Freshness, Export of 21 September 2026

The data behind this site was last exported on 21 September 2026 (21 Sept 2026, 14:17 UTC). Below, every source and every grid zone shows its newest data date, and its age in days is counted from that export date, not from when the site was built. In this export, 2 zones run 2 or more days behind the newest zone in their source. Ember statistics and grid operator data are listed separately and never combined.

Newest Data by Source

export of 21 September 2026

Ember: annual and monthly statistics

Country totals by year and month. These are periods, not readings, so the age counts from the last day of the period.

Ember: annual and monthly statistics: newest data, age and reporting lag.
DatasetNewest dataAge at exportCoverageReporting lag
Ember annual statistics 2025 264 days 93 of 215 countries have this year Published once a year, so the newest full year is normally the previous calendar year. Age is measured from the last day of that year.
Ember monthly statistics August 2026 21 days 38 of 88 countries with monthly data have this month Published monthly, after the month ends; only a subset of countries has monthly figures. Age is measured from the last day of the month.

EIA: US grid operators, hourly and daily

Balancing authorities and regions from Form EIA-930.

EIA: US grid operators, hourly and daily: newest data, age and reporting lag.
DatasetNewest dataAge at exportCoverageReporting lag
EIA hourly demand 21 Sept 2026, 11:00 UTC 0 days 67 balancing authorities and regions About 1 hour behind. Grid operators may revise recent hours.
EIA hourly generation mix 21 Sept 2026, 05:00 UTC 0 days 74 balancing authorities and regions Generation by fuel runs about 10 hours behind demand; net generation and total interchange 10 to 13 hours. Border by border interchange is about 33 hours behind.
EIA daily totals 20 September 2026 1 day 74 balancing authorities and regions Daily totals are per local day and follow the hourly series. Respondents resubmit corrected values, and the site re-reads the trailing 7 days on every run.

ENTSO-E: European bidding zones

Load, generation, day ahead prices, cross border flows and installed capacity from the Transparency Platform.

ENTSO-E: European bidding zones: newest data, age and reporting lag.
DatasetNewest dataAge at exportCoverageReporting lag
ENTSO-E actual load 21 Sept 2026, 12:00 UTC 0 days 48 bidding zones The platform publishes what each transmission operator reports. The usual lag is not documented in our source notes, so read the observed age.
ENTSO-E actual generation by type 21 Sept 2026, 12:00 UTC 0 days 48 bidding zones Reported by fuel type; sources arrive at different times, so the site shows the latest hour in which every regularly reported source is present.
ENTSO-E day ahead prices 22 September 2026 Dated 1 day after the export 47 bidding zones Day ahead prices are set the day before delivery, so the newest price day can be later than the export date (shown as a negative age).
ENTSO-E cross border physical flows 20 September 2026 1 day 1 European flows file The flows page covers a 30 day window ending on the date shown; the export has no daily border series.
ENTSO-E installed capacity 2026 263 days 39 bidding zones Published per calendar year, so the date is the first day of the reference year, and the age shows how long ago that year began.

Age is the number of whole days from the newest data date to the export date (21 September 2026). Hourly figures are in UTC. The newest data is the newest among all zones or countries in the dataset; the tables below show each zone.

Zones Running Behind

2 of 124 zones, export of 21 September 2026

A zone is listed as stale when its newest reading is 2 or more days older than the newest zone in the same source (US grid operators are compared with each other, and European bidding zones with each other). A stale zone has usually stopped reporting to its platform, and its page then shows the last figures published.

Zones that are behind by two or more days. Column headings sort the table.

Great Britain Bidding zone n/a 13 June 2021 1,926 days (stale, 2+ days)

When the Data Refreshes

  • Data job, daily at 06:15 Pacific. It reloads Ember, refreshes EIA and ENTSO-E incrementally, builds the news, derives the figures and writes a new export.
  • Site rebuild, after each data job. The site is rebuilt from the new export and deployed, at about 06:45 Pacific once the data job has finished. Every figure baked into a page carries the date it covers.
  • Live tiles, hourly. A separate job at 25 minutes past each hour loads the latest hourly EIA figures, so live tiles on US pages update without a rebuild.

This is the schedule as configured on the machine that runs the jobs. A job that fails leaves the last good export in place, so the export date at the top of this page tells you what the site was built from. A week of no change on this page means the daily data job is not completing.

Known Reporting Lags

  • Ember. Annual statistics arrive once a year, and the newest full year is normally the previous calendar year. Monthly statistics follow the end of each month and cover fewer countries.
  • EIA hourly. Demand is about 1 hour behind. Generation by fuel is about 10 hours behind, net generation and total interchange 10 to 13 hours, and border by border interchange about 33 hours. Grid operators can revise recent hours, so the site re-reads the trailing 7 days each run.
  • EIA daily. Daily totals follow the hourly series and are revised in the same way; sub-region demand can arrive up to a month late.
  • ENTSO-E. The platform publishes what each transmission operator reports, so lag varies by zone and by dataset. Day ahead prices are published the day before, capacity once a year, and the generation mix is shown for the latest hour in which every regularly reported source is present. The typical load and generation lag is not verified.

Zones that read zero or stop reporting are listed with dates on the data quality page. Figures are shown as the platform published them.
