What happened on 1 November
On 1 November, 3 markets paid buyers to take power at some point: South Australia for 1 h 40 minD, Victoria for 10 minD and Tasmania for 5 minD. The longest unbroken run was in South Australia, 1 h 00 minD from 09:30–10:30 ACDT; the lowest price there during the day was −A$20.00D/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. Great Britain spiked to £272/MWhD (about 364D USD/MWh) in the hour from 16:00 GMT, above our fixed threshold of 300 USD/MWh.
Of the grids where we meter the generation mix, Denmark ran on the highest renewable share, 44.8D % over the day, with wind at 40.1D % and solar at 4.7D %. Great Britain followed at 33.0D % renewable with wind 17.2D % (transmission-metered; solar on local networks is not in this data). Taiwan followed at 10.8D % renewable with wind 0.4D % and solar 8.7D %. Across the 8D markets with a full day of metered demand, 1,835,686D MWh was used, Taiwan the largest at 36.1D % of it.
Time below zero across all markets added up to 1 h 55 minD, less than the 22 h 25 minD on 31 October. Against 31 October, demand moved most in South Australia (+29.6D %) and Victoria (−1.3D %). Denmark's renewable share rose by 16.8D points, from 28.0D %. Great Britain's renewable share rose by 6.2D points, from 26.8D %. Taiwan's renewable share fell by 4.0D points, from 14.8D %. The cheapest hour anywhere cost about −4D USD/MWh, against −195D on 31 October.
How to read this. The 1 November recap covers 15D markets (8D with a full day of demand) and was frozen at 00:30 UTC on 2 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.
