South Australia has the most volatile daily price history in the NEM. Days dominated by wind and solar can produce average prices below $20/MWh; calm evenings with limited gas dispatch produce the opposite extreme.
For background on how AEMO sets NEM dispatch prices, read the wholesale electricity guide. Or jump to the live SA spot price and forecast.
The daily average and 90-day summary above show South Australia’s recent price history, aggregated from 5-minute AEMO dispatch data into daily minimum, average, time-weighted average and maximum figures.
The simple average treats every 5-minute interval equally. The time-weighted average also does this over the trading day, but is the figure most retail and wholesale contracts reference, since it reflects the price actually paid across the full period rather than being skewed by a handful of extreme intervals.
South Australia has the most volatile daily price history in the NEM, driven by its heavy reliance on wind and solar output relative to a small dispatchable generation fleet, so the daily minimum and maximum columns above often sit far apart.
