Regional Outlook — QLD1: Wednesday 2 September 2026
Queensland's spot price sits at $64.95/MWh as of 06:30 AEST, with demand at 6,246 MW. That's well below the overnight peak of $92.55/MWh recorded around 21:00 AEST last night, but a sharp reversal from the negative pricing seen through the early hours (troughs of -$23.59/MWh between 02:00-04:00 AEST) as solar output collapsed overnight and battery/gas plant picked up the slack. The 24-hour trend shows the classic QLD pattern: negative-to-near-zero prices overnight during minimum demand, climbing through the morning ramp as demand builds toward the 7,000+ MW range.
Generation mix at the last snapshot (06:00 AEST) is dominated by black coal at 4,836 MW, with wind contributing 890 MW, batteries at 371 MW, gas (OCGT) at 94 MW, hydro at 33 MW, and solar effectively at zero (0.16 MW) given the pre-dawn timing and current 100% cloud cover locally. Renewable penetration sits at 20.79%, consistent with overnight patterns before solar ramps up — the carbon intensity reading is 0.6936 tCO2/MWh, up from lows near 0.44 tCO2/MWh overnight when wind and hydro carried a larger share of load.
Predispatch forecasts point to a firming price trajectory through today. After further softening toward the $0 to -$20/MWh range between 09:00-14:00 AEST (overnight into early morning UTC-referenced troughs), prices are forecast to climb sharply from 07:00 AEST onward, hitting $78.52/MWh, then $92.55/MWh by 07:30, and peaking near $123.45/MWh around 09:00-09:30 AEST as morning demand ramps against a cloudy start (solar potential forecast at just 35.2% average today, per the outlook). Prices are expected to ease gradually through the afternoon, settling near $78-88/MWh into the evening block by 17:30-18:00 AEST. Traders should note the five identified low-price load-shifting windows overnight (00:30-05:00 AEST), each offering $130-147/MWh savings versus peak — useful for flexible load or battery charging strategies.
On notices, QLD-specific items are limited to system strength constraint updates in North Queensland (effective 27 August, ongoing) and a resolved lightning-related contingency reclassification on the Mudgeeraba-Terranora 110 kV lines. No active QLD non-conformance or intervention events are currently in effect; most live intervention and minimum system load notices this week relate to SA. Traders should be aware of the AEMO MarketNet planned maintenance window on 4 September (10:00-17:00 AEST) which may briefly affect VPN connectivity via the QLD datacentre termination point.
