Context
Highest since we started · Price in NEM South Australia: 139.45 AUD/MWh in the 5-minute interval starting 2026-10-24 11:40 UTC. We have tracked this market since 2026-10-23. The window is short, so this says nothing about earlier years.
It beat the previous value of 130.44 AUD/MWh, set at 2026-10-23 18:25 UTC, by 9.01 AUD/MWh (6.9%). That earlier value stays in the chain as superseded and remains visible at /records/highest-price-sa-1792779900/.
Conditions in the data at the same time: NEM-SA1 demand 1248.4 MW (reading at 11:40 UTC). These are the readings nearest to the tracked interval in the same database, shown for context only; they do not explain the value on their own.
First seen in a batch fetched at 2026-10-24 11:45 UTC (payload c44660ec25). It was checked after a second batch fetched at 2026-10-24 12:00 UTC (payload 417ad181a1): a later batch arrived, this feed does not republish old intervals, and the stored point stayed unrevised, unflagged and within 2%.
For comparison, the next most extreme valid reading in the same series is 250.00 AUD/MWh at 2026-10-24 01:30 UTC, out of 484 readings in the window.
These values are built from provisional operator data that can be revised, so each one is checked against later batches before it is marked Tracking and can be withdrawn if the source changes it. Readings outside market bounds, with a wrong unit, flagged by a quality gate or showing a price jump without a matching load change are rejected and never listed.
