The South Australian spot price sits at $48.05/MWh at 06:30 AEST, with total demand at 1,574 MW. This is materially below the morning peak levels seen earlier today, when prices repeatedly cleared above $100–$150/MWh between 17:30 and 20:00 AEST, with isolated spikes to $300.75/MWh at 19:50 and again at 09:30 AEST (UTC+10:30 translated). The 24-hour price profile shows a pronounced overnight trough — with multiple intervals printing negative, bottoming near -$15/MWh in the early hours — before the morning ramp drove sustained triple-digit clearing prices through the 18:00–20:00 AEST window. The current $48.05/MWh represents a significant softening from that morning peak.
Wind is the dominant generation source right now at 710.95 MW, with gas CCGT contributing 42 MW and solar and gas OCGT both at 0 MW given the pre-sunrise timing. Renewables are contributing 94.42% of grid supply, with carbon intensity at just 0.0273 tCO2/MWh — one of the lowest readings across today's 24-hour window. For context, carbon intensity peaked around 0.519 tCO2/MWh in the 09:30–10:00 AEST window when renewable penetration was below 7%, indicating a very different generation mix during that period, likely with substantially higher gas dispatch to meet peak morning demand.
Predispatch forecasts point to further softening, with the next hour (07:30 AEST) forecast at $41.70/MWh — down from the current $48.05/MWh. Load window signals flag even lower prices through the 08:00–09:00 AEST window, with indicative cleared prices in the range of -$3 to -$4/MWh, rated as excellent quality for flexible load shifting. Demand-side participants and battery operators should note this window as a prime charging opportunity ahead of what is likely to be another price run once solar drops off this evening.
AEMO has issued a high volume of active market notices today, with prices for intervals spanning 03:10 through 06:15 AEST currently flagged as subject to review under Clause 3.9.2B of the National Electricity Rules for Manifestly Incorrect Inputs. Several earlier intervals — including 02:40, 04:10, 04:45, 05:00, and 05:50 — have been reviewed and confirmed unchanged. Traders should be aware that settlement prices across much of today's early morning window remain under review and could be revised. No affected regions are specified in the notices, so the scope of any potential adjustment is not yet confirmed.
