The Five-Minute Price Curve
The first chart shows each five-minute price for South Australia through the day, with times in fixed UTC+10. Timing matters for any operator: a battery or flexible load gains from the gap between the cheapest and dearest intervals, while a generator’s result depends on when its energy was delivered.
How The Five Regions Compared
Daily average prices in the other regions were: Victoria AUD 192.47/MWh, Tasmania AUD 188.67/MWh, New South Wales AUD 184.28/MWh, Queensland AUD 93.14/MWh. The second chart compares the five regional averages for 1 July 2025.
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.
This analysis uses Network Map’s regional observations dated 1 July 2025. Prices are in Australian dollars per megawatt-hour, times use fixed UTC+10, and daily averages give equal weight to each five-minute observation.
