Demand since 00:00 UTC: the trapezoid integral of metered readings, summed over the markets below. Between readings the count runs at the last metered rate for at most 15 minutes, then stops until new data arrives.

Great Britain counts metered transmission generation (Elexon FUELINST, 5-minute), not demand.

EIA publishes hourly, about 1–5 hours behind; we never extrapolate. Times are UTC.

Yesterday is the previous UTC day: final once all 24 hours are published, until then the sum of the hours so far, marked partial (never scaled up). Latest is the newest hourly reading, as of the end of its hour (UTC). Source: U.S. EIA Hourly Electric Grid Monitor (EIA-930), preliminary.

Live counters

Spent on wholesale power today $179,400,574D Metered demand × price
Wholesale value of metered demand at each market’s published price, in USD at the ECB rate (AUD 0.7026, 2026-10-29) (GBP 1.3317, 2026-10-29). Excludes networks, taxes and retail margins. The count can run down when a price is negative.

Great Britain: transmission generation (Elexon FUELINST, as in the main counter) at the half-hourly Market Index (MID) price, not the imbalance price. Australia: regional demand at the 5-minute price (RRP). Denmark is not in this card: DK1 and DK2 have a day-ahead price but no metered area demand, and national demand has no single price.

Only markets with a full metered day of both series count; between readings the last metered rate runs for at most 15 minutes. A market whose latest price or demand is older than that stays fixed at its last complete metered point and stops adding (listed as held in the line below the figure) while the other markets keep flowing; the card pauses only when every market is held.

Wind vs gas now Wind1.5 GWM Gas14.6 GWM Wind ahead today: 00:00:00D
Latest metered wind and gas output of Great Britain (Elexon FUELINST, 5-minute). The stopwatch is the total time since 00:00 UTC in which metered wind was above metered gas; each reading counts for its own interval, and it runs on for at most 15 minutes past the last reading, only while wind is ahead. Denmark has no metered gas series, so only Great Britain is compared.

Sunset wave 03:45:14D Taiwan sunrise 0.0 GW · steadyM
Countdown to the next sunrise or sunset at a fixed reference point per market: Denmark Odense (55.40 N, 10.39 E), Taiwan Taichung (24.15 N, 120.67 E). Computed with the NOAA solar-position equations (astronomy, not data). The market with the soonest event among those with fresh metered solar is shown. Solar is the latest metered value; rising, falling or steady compares it with the reading 30 minutes earlier (under 2 % is steady). Great Britain publishes no metered solar.

The cheapest of the latest published prices across the markets listed, converted to USD per MWh at the ECB rate. Ties go to the alphabetically first market. The stopwatch counts how long this market has been on top, from the price history; it stops 15 minutes after its latest price. Great Britain uses the Market Index (MID) price, Denmark the day-ahead price, Australia the 5-minute price.

How the electricity clock works

The large counter adds up the electricity used since 00:00 UTC in the markets whose operators publish readings at least every 30 minutes: Great Britain, Denmark, the five regions of Australia’s National Electricity Market (New South Wales, Queensland, Victoria, South Australia and Tasmania) and Taiwan. The figures come from Elexon’s BMRS, Energinet’s Energi Data Service, AEMO’s NEMWEB and Taipower’s open data, each shown with the attribution its licence requires.

For every market we join today’s metered readings with straight lines and add up the area under them. Between two readings your browser keeps counting at the last metered rate for at most 15 minutes; if no new reading has arrived by then, that market stops and is marked paused until data returns. A market joins the day’s total only once its readings cover at least 95 % of the UTC day so far. “Metered to” is the latest time that most counted markets have reached.

Great Britain is counted from Elexon’s FUELINST data, the five-minute output of transmission-connected power stations, because the half-hourly demand series arrives about an hour late. That makes the British figure generation, not consumption. Danish demand is not published in near real time, so we calculate it from Energinet’s production and cross-border exchange data.

Every number carries a badge. Metered (M) is a value the operator measured and published. Derived (D) is arithmetic on metered values, such as a daily total, a renewable share or a currency conversion. Estimated (E) is a model: the CO₂ counter multiplies metered generation by the lifecycle emission factors of IPCC AR5 Working Group III.

The five U.S. grid operators come from the EIA-930 report, which is hourly, preliminary and published hours after the fact. They sit in their own block in the “Where it’s used” list and never tick.

The methodology explains every rule, the board shows the latest reading per market, and the status page shows how current each source is.

Questions and answers

Is the counter live or simulated?

Its total is built from metered readings. Between readings it continues at the last measured rate for up to 15 minutes, then pauses; it never fills a gap with a forecast.

Why does Great Britain count generation instead of demand?

Elexon’s five-minute FUELINST generation data is current, while the half-hourly demand series arrives about an hour late. Imports through interconnectors are excluded because that power is generated abroad.

Why are the U.S. grids not in the main counter?

EIA-930 data is hourly, preliminary and delayed by hours, so it cannot follow the clock. The U.S. block shows the latest published hour instead.

What does paused mean?

The market has sent no new reading for 15 minutes. The counter keeps its last value and resumes when data arrives.
