Australia Grid Edge Conditions: September 2026, revision of grid-edge-2026-09 (2026-10-04). 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.

Trust declaration

Fitness, limits and the check performed.

Publication contract pass

Suitable for the named scope when used with the published vintage, confidence and known limit. It is not a substitute for project-specific diligence.

Institutional environment: documented; AEMO NEMWeb, AEMO WEM, Ember and Solar Analytica evidence ledgers is named as source; Solar Analytica owns the published transformation and limits.
Relevance: documented; Five NEM regions and the South West Interconnected System
Accuracy and reliability: documented; Operational metrics are compared only where unit and measurement basis match. National annual carbon context is not relabelled as regional real-time carbon.
Timeliness: partial; Monthly edition after daily operating ingestion. The product is recovering, so its next check cannot be relied on; the recorded date is 2026-11-01.
Accessibility: documented; Public landing page at /grid-edge-conditions; JSON trust metadata and catalogue metadata are open.

Source check: sourceCheckedAt satisfies the source_check date basis.

Freshness records which declared date satisfies the product's registered basis. Dependency causes describe upstream operational state. Neither establishes source correctness or a changed decision outcome.
