Regional Outlook — QLD1 — Monday 4 May 2026

Queensland's spot price sits at $82.49/MWh with total demand at 6,495 MW as of 06:35 AEST. The price profile across today tells a clear story: overnight intervals trade in the $22–$55/MWh range before surging through the morning ramp, with the 17:00–19:30 AEST window producing a sustained band of $91–$94/MWh that has since eased only modestly into the current interval. The session peak reached $99.84/MWh at 21:40 AEST. Averaging across today's price history, the mean sits comfortably above $70/MWh, reflecting a structurally elevated day driven by the autumn morning and evening demand peaks as heating loads displace the solar contribution that compressed prices through the shoulder season.

The generation mix is dominated by black coal at 2,246 MW, with hydro contributing 86 MW and gas OCGT at a negligible 0.06 MW. Solar output is zero, consistent with the post-sunset timing of the latest data point (06:30 AEST). Renewable penetration stands at just 3.69%, and with 94% average cloud cover forecast for today, solar uplift through daylight hours will be constrained — the daily solar potential index sits at only 1.5 out of a maximum scale. Carbon intensity is 0.8475 tCO2/MWh, consistent with the daytime band maintained since approximately 15:00 AEST after overnight wind and hydro contributions briefly pushed intensity down to 0.659 tCO2/MWh around midnight.

Predispatch forecasts signal a notable price escalation into the next two half-hour periods. The 07:00 AEST half-hour is forecast at approximately $93/MWh, rising sharply to $117–$120/MWh by 07:30 AEST and further to $122–$124/MWh by 08:00 AEST. This trajectory is consistent with the morning demand ramp pushing toward the 7,600–7,800 MW range observed earlier in today's session. Forecast values for 08:30–09:00 AEST indicate prices in the $117–$124/MWh zone, suggesting the morning peak remains ahead and that any flexible load with capacity to shift to the 09:30–10:00 AEST window — where predispatch points toward $39–$53/MWh — carries meaningful bill reduction potential.

The one active market notice directly relevant to Queensland is the Directlink inter-regional transfer limit variation (Notice 144047), which records an unplanned outage of the No.3 leg of Directlink and invocation of constraint set N-MBTE_1 affecting the N-Q-MNSP1 interconnector from 02:30 AEST today. This reduces the effective transfer capacity between Queensland and NSW on that path, which can tighten QLD pricing when the state is a net exporter or reduce arbitrage headroom. Additionally, AEMO issued a general notice (144024) effective today increasing the cap on dispatch of Very Fast Contingency FCAS in QLD from 200 MW to 250 MW during periods where islanding is considered credible — relevant for frequency control service participants and battery operators optimising FCAS co-optimisation bids in today's dispatch.
