- Worth noticing
- Forecasts count only when issued before the target interval, and are compared with AEMO’s pre-dispatch forecast and the price actually set.
Field notes
The Atlas is described as a replayable record of five-minute intervals, with price, demand, generation, spare capacity, and battery data across the regions. Its day tape counts intervals above $300/MWh and below zero. The site also links five research notes covering spike clustering, price changes from FY22 to FY26, pre-spike departures from daily price patterns, and how price risk is shared across the network.
