Regional Outlook — QLD1: Monday 7 September 2026
Queensland's spot price sits at $84.73/MWh as of 06:30 AEST, tracking near the middle of a volatile 24-hour band that swung from a negative floor of -$3.00/MWh overnight to a peak of $132.99/MWh through the 18:00-18:40 UTC window (roughly 04:00-04:40am AEST demand ramp). Demand has climbed to 6,386 MW, up sharply from the sub-4,100 MW trough recorded around 00:00-01:00 AEST when negative pricing persisted for close to four hours. The evening peak this cycle topped out near $133/MWh during the morning commercial ramp, consistent with typical weekday demand-driven volatility rather than any supply-side event.
Generation mix at the current interval is dominated by black coal at 5,362 MW, the clear baseload anchor for the region. Wind is contributing 477 MW and batteries are dispatching 639 MW, likely responding to the price ramp into the evening peak. Solar has dropped to just 76 MW as the panel fleet winds down for the day, gas OCGT sits at 98 MW, and hydro adds a modest 30 MW. Renewable penetration reads 18.28% at this interval, well down from the overnight peak of 47-48% recorded between 02:00 and 05:00 AEST when demand was low and wind/solar carried a larger share of a smaller total load.
Carbon intensity has risen to 0.7157 tCO2/MWh, up from an overnight low near 0.45 tCO2/MWh and consistent with the inverse relationship between demand, coal dispatch share, and renewable penetration seen through the day — intensity peaked near 0.79 tCO2/MWh in the 17:00-18:00 AEST window as solar output faded. AEMO's predispatch forecast points to easing prices through the day: $78.57/MWh by 07:00 AEST, dropping to single digits and briefly negative ($-1.36/MWh) between 10:00-10:30 AEST as the operational demand trough sets in, before a fresh morning ramp lifts prices to a forecast peak of $94.25/MWh around 19:00 AEST tomorrow. Traders should note the low-price windows flagged by the load-shifting model, particularly 09:00-10:30 AEST, which show near-zero carbon intensity and $92-141/MWh savings versus peak.
No Queensland-specific market notices are active in the current notice board — recent AEMO bulletins concentrate on VIC (a since-cancelled LOR1 forecast for 08/09), SA voltage interventions, and TAS/VIC lightning-related contingency reclassifications, none of which carry direct implications for QLD dispatch or interconnector flows today. Weather across the region shows mild conditions (14.7°C, overcast, 81% cloud cover) with today's outlook of 15.2-22.6°C, limiting rooftop solar output through the morning — a factor likely reinforcing the higher intraday carbon intensity readings.
