About the data
We snapshot the Australian Energy Regulator's public plan data daily (since 12 Jun 2026; monthly history to Sep 2025 via the open-energy-tracker project, MIT). 48,101 plans tracked, 49 rate changes captured. The regulator's API only shows today's plans — history exists because someone archived it.
Two provenance tiers, always visible in results: daily-walk — our own snapshots of the CDR Product Reference Data. Per-retailer re-visit is multi-day (shared capture budget), not true daily — use each brand's window in the table, never a uniform cycle; monthly-archive — the open-energy-tracker project's monthly commits (first-listed dates and point-in-time tariffs only). Benchmarks state the observation window rather than pretending to a resolution we don't have.

Honesty notes
- AGL and Origin joined the walk late (their endpoints 404'd until a 2 Jul 2026 fix); their first full snapshots land as the current cycle wraps. Until then, benchmarks simply won't include them — we never backfill by guessing.
- Bill estimates are annualised from a flat load profile: exact for single-rate and block plans, time-coverage weighted for time-of-use plans, and demand tariffs are excluded. Discounts, fees, solar feed-in and controlled load are not modelled.
- A handful of holders publish no plan data at all (mostly B2B and embedded-network retailers).
