The Five-Minute Price Curve
The first chart shows each five-minute price for New South Wales through the day, with times in fixed UTC+10.

Daily average prices in the other regions were: Queensland AUD 346.27/MWh, South Australia AUD 84.40/MWh, Victoria AUD 72.88/MWh, Tasmania AUD 57.64/MWh. The second chart compares the five regional averages for 25 May 2023.
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.
