Context

Lowest price in NEM South Australia: 86.44 AUD/MWh in the 5-minute interval starting 2026-10-24 09:40 UTC. This is a record since 2026-10-23, the first date in our data for this market. The window is short, so the record says nothing about earlier years.

Conditions in the data at the same time: NEM-SA1 demand 1418.8 MW (reading at 09:40 UTC). These are the readings nearest to the record interval in the same database, shown for context only; they do not explain the record on their own.

Records are built from provisional operator data that can be revised, so each one is checked against later batches before it is confirmed and can be retracted 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. See the methodology page for the full rules. Not for trading or operational decisions. Provisional data.
