NEM and SWIS operating conditions in one fixed release, with every metric kept on its native market, unit and measurement basis.
Edition read
53 publishable metric rows across 2 Australian grid systems, with measurement bases retained for every value.
Correction, 4 October 2026: The first edition published each NEM region's negative-price share as 0 per cent from 31 July 2026, before this period began, and recorded falls of 100 per cent in four regions as material, because the daily ingest did not record how many price intervals each day held; this revision rebuilds September from the completed daily record. This edition supersedes grid-edge-2026-09. Corrections ledger
Reading boundary
The NEM chart uses five-minute regional price spreads. SWIS is excluded because this edition does not yet carry a directly comparable WEM price series.

Machine-readable edition
Metric key, unit and comparison basis must all match. National annual context remains labelled as context and is not relabelled as regional real-time data. A missing value remains null and is never converted to zero. An operating value is published for the edition's month only when its own observations reach into that month and leave no run of more than 3 days unobserved; otherwise the row is published as not available.
