regional sa — SA1
The South Australian spot price sits at $107.84/MWh against a total demand of 1,524 MW at 07:00 AEST. Contextualising that against the past 24 hours, SA has seen significant intraday volatility — prices spiked to $370/MWh during the overnight period around 09:40 AEST and dipped into negative territory (as low as -$2.69/MWh) in the early hours, before settling into a relatively stable $90–$125/MWh band through the morning and afternoon trading periods. The current price is broadly in line with the day's prevailing range, suggesting no acute stress at this moment.
The generation mix is entirely thermal and wind at this interval, with solar contributing 0 MW given the pre-dawn timestamp. Wind is carrying 459 MW and gas CCGT is providing 257 MW, with gas OCGT offline. Renewables are contributing 64.08% of regional generation, consistent with the strong wind penetration SA regularly achieves overnight. Carbon intensity sits at 0.176 tCO2/MWh — a clean result relative to the day's earlier high of 0.497 tCO2/MWh recorded around 10:00 AEST when wind output was lower and gas was carrying more load. The trend through the evening hours has been firmly downward on carbon intensity as wind has strengthened, dropping from 0.39 tCO2/MWh at 17:00 AEST to the current 0.176 tCO2/MWh.
Predispatch forecasts for the next trading period point to $110.44/MWh, broadly flat to the current price. Load window modelling identifies an excellent opportunity window opening around 08:30–09:00 AEST, with forecast prices falling to the $10–$35/MWh range — likely driven by anticipated solar generation entering the mix as sunrise progresses and wind remaining firm. Traders and flexible load operators should note this window as a strong candidate for discretionary consumption or battery charging, with savings estimates exceeding $100/MWh relative to current levels.
On market notices, there are no active contingency reclassifications directly affecting SA1. The active Queensland notice — reclassification of the Kamerunga–Barron Gorge 132kV double circuit as a credible contingency event due to lightning — has no direct constraint implications for SA at this time. AEMO has issued a high volume of Manifestly Incorrect Inputs review notices across early morning intervals (01:00–04:00 AEST), with confirmed prices unchanged on all resolved intervals to date. The 03:55 AEST interval remains subject to review; traders with exposure to that settlement period should monitor for confirmation.
