Regional Outlook — NSW1: Sunday 16 August 2026
NSW spot price sits at $57.92/MWh at 06:25 AEST, with demand climbing to 8,701 MW as the morning ramp builds. Prices overnight ranged from lows near $16-25/MWh in the 03:00-04:00 window through to a sharp morning peak of $90.08/MWh at 16:30 UTC (02:30 AEST evening peak equivalent), reflecting the typical demand-driven volatility of the past 24 hours. The five-minute trend shows prices easing back from that peak as the morning progresses, though predispatch signals a firmer session ahead.
Generation mix is currently led by black coal at 5,945.65 MW, comfortably the largest contributor, followed by wind at 1,477.68 MW and hydro at 714.4 MW. Solar sits at just 107.68 MW given the pre-dawn interval, gas OCGT contributes a modest 49.66 MW, gas CCGT is offline at 0 MW, and battery output is negligible at 0.15 MW. Renewable penetration reads 27.73%, down from an overnight peak above 49% around midnight as wind and hydro carried a larger share of load during low-demand hours. Carbon intensity has risen accordingly to 0.6346 tCO2/MWh, up from a low of 0.4404 tCO2/MWh at 04:00 AEST, tracking the inverse relationship between renewable share and demand through the morning ramp.
Predispatch forecasts show prices firming through the morning, with the 07:30-09:00 AEST window forecast in the $83-88/MWh range as demand peaks, before easing to the low $40s/MWh by early afternoon and holding flat near $42.80/MWh through evening trading. This pattern points to a classic morning peak followed by a soft midday-to-evening trough, consistent with strong solar contribution expected later in the day offsetting demand. Weather today shows modest solar potential (10.6% average) and minimal wind (1% average) under cloudy conditions, tempering renewable output relative to recent days.
On notices, an inter-regional transfer limit variation remains active following a short-notice outage of the Lismore 132 kV line (constraint N-LSLS_9U8, invoked 15 August), and Directlink control remains unavailable pending further advice, both affecting interconnector flows with QLD. The Bayswater-Sydney West 330 kV line outage from 10 August has since been resolved. No non-conformance or intervention notices are currently active for NSW. Traders should note the current grid stress score of 87.4 (elevated) alongside a price stability score of 45.9, reflecting the volatile morning ramp conditions.
