Commodity Demand — QLD1

Queensland spot price sits at $71.75/MWh with demand at 5,734 MW as of 06:35 AEST, a level consistent with the overnight-to-morning transition on a Sunday. Today's demand trajectory traces a familiar autumn Sunday shape: prices collapsed to zero and into negative territory — reaching as low as -$2.49/MWh — through the overnight trough between roughly 01:00 and 15:00 UTC (11:00 AEST–01:00 AEST), before the morning ramp drove demand from a floor near 5,175 MW up through 7,210 MW at the 18:05 AEST peak, pulling prices firmly into the $60–$72/MWh band. The price-to-demand relationship today has been tight: every sustained move above 6,500 MW has anchored spot at or above $60/MWh, while sub-5,400 MW intervals repeatedly cleared at zero or below.

The current 5,734 MW reading marks the beginning of demand's second daily descent. With no solar output registered at this hour (06:35 AEST) and generation comprising 2,333 MW black coal, 86 MW hydro, and negligible OCGT, the supply stack is tight relative to overnight conditions. AEMO forecasts point to a step-down in price from the current $71.75/MWh to around $64.83/MWh by the 07:00 AEST half-hour, then a sharper drop to approximately $52/MWh by 07:30 AEST as Sunday morning demand retreats. The forecast RRP for the 08:30 AEST interval sits at roughly $29–$30/MWh, consistent with demand falling back into the 5,200–5,400 MW range typical of a Sunday late morning.

For demand-side managers, the window from approximately 08:30 AEST through mid-afternoon represents the most attractive load-shifting opportunity of the day, with load windows pricing negative across multiple intervals from 08:30 AEST onward — some reaching below -$25/MWh in the 10:00–11:00 AEST range. The absence of demand-side notices specific to Queensland load is notable; market notices active today relate to the Mudgeeraba–Terranora 110 kV line contingency reclassifications (resolved by 12:14 AEST Saturday) and the NSW Newcastle–Eraring interconnector outage which returned to service at 13:50 AEST Saturday, restoring full inter-regional transfer capability on that corridor ahead of today's trading.

The price outlook for the remainder of Sunday is soft. Forecast RRPs track below $55/MWh from 07:30 AEST and do not recover materially until the late-afternoon demand rebuild. The evening ramp — typically commencing around 16:00–17:00 AEST in autumn — will be the next test for the $70/MWh threshold, though Sunday evening demand in Queensland rarely replicates the severity of weekday peaks. Carbon intensity holds at 0.8488 tCO₂/MWh with renewables at 3.55%, and is not expected to shift materially until solar output lifts post-sunrise.
