Regional Outlook — NSW1: Monday 24 August 2026
NSW spot price sits at $95.20/MWh as of 06:30 AEST, tracking near the top of an overnight range that swung from a negative print of -$6.62/MWh around 03:45 AEST to a peak of $119.96/MWh at 18:00 AEST yesterday evening. Demand is at 7,931 MW and climbing through the morning ramp, consistent with the pattern seen over the past 24 hours where demand troughed near 4,970 MW in the early hours and peaked above 9,400 MW during the evening block. Predispatch forecasts show prices holding in the $70-75/MWh band through this morning before a strong afternoon ramp, with forecast RRP reaching $118-119/MWh between 18:00 and 19:30 AEST as evening demand builds — traders should watch the 17:30-19:00 AEST window closely.
Generation mix at the latest interval shows black coal dominant at 5,444.87 MW, wind contributing 1,596.13 MW, hydro at 789.47 MW, solar at 94.95 MW, battery output at 78.97 MW, and gas OCGT at a modest 40.21 MW, with gas CCGT offline. Renewable penetration sits at 31.82%, up from an overnight low near 24.7% around midday yesterday, reflecting the diurnal wind and hydro contribution pattern typical for this region. Carbon intensity reads 0.5989 tCO2/MWh, easing from a daytime peak of 0.6614 tCO2/MWh but still elevated relative to the overnight minimum of 0.3691 tCO2/MWh recorded around 02:00 AEST when renewable share exceeded 57%.
Weather conditions today are unfavourable for solar, with cloud cover at 96% and solar potential effectively at zero this morning; the daily outlook confirms full cloud cover (100%) for 25 August with wind potential a modest 4.2. This points to coal and hydro carrying more of the generation load through today's peak periods, with limited rooftop and grid-scale solar offset. Temperatures are mild (14.9°C currently, forecast max 19.6°C), keeping heating and cooling demand contributions low.
Active market notices relevant to NSW include two inter-regional transfer limit variations from the past week — the Vineyard to Sydney West No. 29 330kV line outage has been completed and returned to service, and the Lismore to Koolkhan 967 132kV line experienced a short-notice outage on 21 August invoking constraint set N-KKLS_967, which affects the NSW-QLD interconnector via N-Q-MNSP1. No new NSW-specific interventions or non-conformance declarations are active today; recent intervention activity has been concentrated in SA and TAS regions. Traders should monitor for fresh predispatch revisions given the low-solar, coal-and-hydro-led generation profile expected to persist through today's peak.
