Five-minute NEM historical trading prices

One region per CSV; one row per five-minute interval. RRP in nominal AUD/MWh.
interval_end_aest is the end of the interval, fixed UTC+10 (no daylight saving).
Month boundaries: first day 00:05 through next month first day 00:00 inclusive.
TRADE rows only. No forecasts, interpolation or missing-interval replacement.
Each month has complete, unique intervals and reconciles to the published AVGRRP
within 0.005001 AUD/MWh (published source rounding). Negative values are retained.
This is historical public RRP, not a settlement invoice, retail tariff or forecast.
All-region coverage means the five NEM regions, not WA or NT. NSW1 includes ACT.
Source URLs, original/CSV hashes, acquisition dates and reconciliation results
are in manifest.json. Hashes identify bytes, not a guarantee of source accuracy.
Older retained sources keep their original acquisition date; the build date is
not a new source check. Source files can be revised by AEMO after acquisition.
