What happened on 12 November

On 12 November, 3 markets paid buyers to take power at some point: South Australia for 3 h 40 minD, Victoria for 2 h 00 minD and Tasmania for 1 h 45 minD. The longest unbroken run was in South Australia, 2 h 20 minD from 11:50–14:10 ACDT; the lowest price there during the day was −A$28.52D/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. South Australia spiked to A$361/MWhD (about 246D USD/MWh) in the hour from 14:30 ACDT, more than three times the 30-day median of 56D USD/MWh.

Of the grids where we meter the generation mix, Denmark ran on the highest renewable share, 79.5D % over the day, with wind at 75.8D % and solar at 3.7D %. Great Britain followed at 51.4D % renewable with wind 40.2D % (transmission-metered; solar on local networks is not in this data). Taiwan followed at 11.9D % renewable with wind 2.9D % and solar 7.7D %. Denmark wind reached 6.9 GWD, highest since we started (23 Oct 2026). Across the 8D markets with a full day of metered demand, 2,052,321D MWh was used, Great Britain the largest at 35.1D % of it.

Time below zero across all markets added up to 7 h 25 minD, less than the 11 h 35 minD on 11 November. Queensland stayed above zero this time. The biggest day-on-day moves in electricity used were Denmark at +10.9D % and Great Britain at −10.4D %. Denmark's renewable share rose by 28.5D points, from 51.0D %. Great Britain's renewable share rose by 26.8D points, from 24.6D %. Taiwan's renewable share fell by 6.1D points, from 18.0D %. The cheapest hour anywhere cost about −6D USD/MWh, against −52D on 11 November.

How to read this. The 12 November recap covers 15D markets (8D with a full day of demand) and was frozen at 00:30 UTC on 13 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.
