The Five-Minute Price Curve
The first chart shows each five-minute price for Queensland 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: New South Wales AUD 175.27/MWh, Tasmania AUD 61.01/MWh, South Australia AUD 27.97/MWh, Victoria AUD 25.45/MWh. The second chart compares the five regional averages for 17 December 2024.
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 17 December 2024. Prices are in Australian dollars per megawatt-hour, times use fixed UTC+10, and daily averages give equal weight to each five-minute observation.
