Commodity Demand — NSW1: Monday 29 June 2026
NSW spot sits at $105.10/MWh with demand at 8,799 MW at 06:25 AEST, tracking the characteristic post-overnight-trough recovery that typifies winter Tuesday mornings. The price history over the past ten hours tells a clear demand-price story: demand peaked at 10,859 MW around 18:05 AEST with prices touching $173.62/MWh during the 07:35–08:00 window, then eased progressively through the mid-morning as commercial load stabilised in the 10,000–10,300 MW range at $91–$98/MWh. The afternoon solar-adjacent trough pulled demand to a session low of ~7,036 MW at 03:55 AEST with prices compressing to the $99–$107/MWh band — notably elevated for that demand level, reflecting tight overnight supply-stack conditions. Demand is now climbing again from that post-sunset base, up roughly 1,760 MW over the past two hours, with prices responding in step.
The generation mix at 06:30 AEST shows black coal carrying 6,075 MW, wind contributing 1,308 MW, hydro 1,186 MW, gas OCGT 213 MW, and battery dispatch at 33 MW, with solar effectively zero in the pre-dawn period. The grid stress score of 68 reflects the tightening supply margin as demand builds into the morning peak. Carbon intensity sits at 0.6222 tCO2/MWh with renewables at 28.66% — consistent with overnight figures — and will be pressured upward as demand rises faster than wind can compensate, given 93% forecast cloud cover today constraining solar across the day.
The forward price curve points to a clear escalation through the morning peak. Forecasts step from $111.55/MWh at 07:00 AEST to $125.35/MWh by 07:30, before easing back through $121/MWh into the 08:00–09:00 window. The 09:30 AEST interval carries the sharpest forecast at $134.89/MWh — the highest point in today's curve — which aligns with sustained high demand in the 10,000+ MW range typical of mid-morning commercial and industrial load before any midday easing. Prices then step down progressively through the afternoon, reaching a forecast low of $66.94/MWh at 02:00 AEST (17:00 today local) as demand retreats toward the inter-peak trough.
Two network factors carry direct demand-side relevance today. The Balranald–Buronga X3 220kV line outage, rescheduled for completion at 01:00 AEST, constrains the NSW–Victoria Murraylink corridor (V-S-MNSP1) via the active N-BABU constraint set; any tightness in that transfer path during the morning ramp reduces NSW's ability to draw on Victorian capacity, putting additional pressure on the local supply stack at exactly the point demand is building most sharply. Flexibility managers should treat the $134.89/MWh forecast at 09:30 AEST as the primary exposure window and note the $66.94–$74.05/MWh corridor between 02:00–03:00 AEST (17:00–18:00 today) as the lowest-cost load window of the day, offering up
