Daily average prices in the other regions were: Queensland AUD 100.86/MWh, Tasmania AUD 44.98/MWh, Victoria −AUD 18.71/MWh, South Australia −AUD 27.00/MWh. The second chart compares the five regional averages for 12 December 2022.

What The Day Means For Operations
For a battery operator, the question is where charging and discharging belonged within this curve. For a generator or retailer, the same timestamps show which intervals carried the most value or cost. Reviewing the day interval by interval keeps these signals visible where a daily average would hide them.
