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 September 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.
