Can I compare the British and Danish prices directly?

Not as like for like. Great Britain’s figure is an imbalance price, Denmark’s is a day-ahead auction price and Australia’s is a real-time dispatch price; each answers a different question.

Why do the U.S. rows show only demand?

The board publishes a price only from a source whose licence allows republication. For the U.S. grids it shows EIA-930 demand, which is public data.

What does a dash mean?

The market does not publish that figure, or not in a form we may republish. It is not a zero.

Why do the rows show different times?

Each source publishes on its own schedule: every five minutes in Australia, every half hour in Great Britain, hourly with a delay in the U.S. Every row shows its own as-of time.

What happened on 11 November

4 markets spent time below zero on 11 November: South Australia for 7 h 20 minD, Victoria for 1 h 30 minD, Tasmania for 1 h 25 minD and Queensland for 1 h 20 minD. The longest unbroken run was in South Australia, 5 h 55 minD from 11:35–17:30 ACDT; the lowest price there during the day was −A$169D/MWh. All of it fell in local daytime, the hours when solar output in the NEM is available. This site does not publish a generation mix for the NEM regions, so the solar and wind share in those intervals is not shown. Tasmania spiked to A$1,984/MWhD (about 1,361D USD/MWh) in the hour from 14:00 AEDT, above our fixed threshold of 300 USD/MWh.

Denmark had the cleanest mix of the grids we meter, 51.0D % renewable over the day, with wind at 43.9D % and solar at 7.1D %. Great Britain followed at 24.6D % renewable with wind 13.8D % (transmission-metered; solar on local networks is not in this data). Taiwan followed at 18.0D % renewable with wind 8.6D % and solar 8.0D %. Across the 8D markets with a full day of metered demand, 2,087,520D MWh was used, Great Britain the largest at 38.5D % of it.

Time below zero across all markets added up to 11 h 35 minD, less than the 19 h 45 minD on 10 November. New South Wales stayed above zero this time. The biggest day-on-day moves in electricity used were New South Wales at +13.2D % and Great Britain at −4.9D %. Denmark's renewable share rose by 20.1D points, from 30.9D %. Great Britain's renewable share rose by 5.5D points, from 19.1D %. The cheapest hour anywhere cost about −52D USD/MWh, against −17D on 10 November.

How to read this. The 11 November recap covers 15D markets (8D with a full day of demand) and was frozen at 00:30 UTC on 12 November; later operator revisions are not applied. A D badge marks a number we calculated from the operators' metered data, an M badge one published as is. Durations add up priced intervals below zero, clock times are each market's local time, and shares are energy-weighted over the day. Definitions and limits are in the methodology.

ⓘ How this recap is made

Built once after the UTC day ended, then frozen. Electricity used is the metered demand of each market added up over the day (Great Britain: transmission generation); only markets with at least 95 % metered coverage of the day are added up. Hours are UTC hours priced as the mean of the source periods. Below zero is the sum of priced intervals under zero. Nothing is estimated or filled in.
