Regional Outlook — QLD1 — Friday 1 May 2026

The Queensland spot price sits at $64.65/MWh as of 06:35 AEST with total demand at 5,940 MW — a significant step down from the morning peak that reached $231.70/MWh at 22:10 AEST and sustained values above $85/MWh through the 17:00–19:00 AEST window. The overnight trough ran as low as $5.60/MWh in the early hours, reflecting the familiar demand valley. Today's Saturday load profile is tracking lighter than the weekday pattern evident in the price history, with demand having already shed roughly 1,800 MW from yesterday's peak above 7,700 MW.

The generation mix at the most recent interval is dominated by black coal at 1,934 MW, with hydro contributing 86 MW and gas OCGT at a negligible 0.06 MW. Solar output is zero at this hour, consistent with the current pre-dawn window. Renewable penetration sits at 4.27%, and carbon intensity is 0.8424 tCO2/MWh — flat and unchanged across the evening, having been as high as 0.8515 tCO2/MWh at the previous day's peak and as low as 0.6507 tCO2/MWh around 10:30 AEST overnight when renewables were contributing 26% of output. Today's cloud cover is forecast at 71% average with a maximum temperature of 23.3°C, which will limit solar generation upside but keep cooling demand minimal. Solar potential is rated 4.5 on average for the day, suggesting some midday contribution once the sun rises, though meaningful renewable penetration will require clearer conditions than the current 97% cloud cover at 18°C implies for early morning periods.

Predispatch forecasts point to $64.65/MWh holding through the 07:00 AEST interval, then stepping down to approximately $55.53/MWh by 07:30 AEST — consistent with Saturday morning demand softness. Load window data indicates prices are expected to fall further into the $35–40/MWh range from 08:30 AEST, with deep discounts from 09:00 AEST onward as forecast intervals show values ranging from near zero to negative through the 09:30–13:30 AEST window. This is a strong signal for flexible load — the 10:00–12:00 AEST window is flagged "excellent" across virtually all forecast runs, with multiple intervals projecting prices at or below $0/MWh.

Two market notices are directly relevant to Queensland today. AEMO issued a general notice on 1 May confirming that from 5 May 2026, the cap on Very Fast Contingency FCAS dispatch in QLD will increase from 200 MW to 250 MW during periods where QLD islanding is considered credible — a change with implications for frequency response cost allocation and intra-regional constraint behaviour. Additionally, the QNI interconnector remains restricted under constraint set I-QN_550 due to an outage on the Armidale–Sapphire 330 kV line, scheduled until 17:00 AEST today (2 May). This constraint limits northward flow capacity from NSW into QLD and is a contributing factor to the price structure observed across the interconnected regions. Traders should monitor for constraint set revocation around the 17:00 AEST window, as QNI
