Commodity Demand — NSW1: Friday 7 August 2026
NSW demand sits at 8,459 MW at 06:30 AEST, with spot price at $109.96/MWh — a level that has held steady across the past 30 minutes as the morning ramp builds. Overnight demand troughed near 6,300-6,500 MW between 03:00-05:00 AEST, with prices collapsing to between -$4.30 and $0/MWh during that window as minimum demand met must-run generation. The relationship between demand and price today is highly elastic: every 1,000-1,500 MW swing in load is moving price by $50-100/MWh, reflecting a tight supply stack where black coal (5,663 MW) is carrying the bulk of load and battery output (435 MW) is being called on to smooth the ramps.
The overnight price data shows this sensitivity clearly — demand fell from 10,957 MW at 07:30 AEST yesterday evening to 6,383 MW by 12:30 AEST overnight, and price fell in near lockstep from $113.50/MWh to $26.69/MWh over the same period. This morning's demand trajectory is now retracing that path in reverse: load has climbed from the 6,300 MW trough to 8,459 MW in the space of four hours, pushing price back above $100/MWh. AEMO's forecast has the region's price easing to $69.99/MWh by 22:00 AEST tonight before a secondary evening peak, with the afternoon trough between 14:00-18:00 AEST forecast in the $70-85/MWh range as solar output (currently 122 MW, low due to 2% cloud cover but limited winter sun angle) contributes modestly.
Looking at today's full trajectory, forecast prices show a classic winter demand curve: a morning peak building toward $121-135/MWh between 09:00-11:30 AEST as commercial and residential heating load stacks on top of the ramp, a midday easing as solar contributes, and a secondary evening peak. Heating demand is currently elevated at 11.3 (on the platform's demand index) with temperatures at 6.7°C, consistent with winter morning heating load driving the current 8,459 MW reading. No demand-side notices (load shedding, non-conformance affecting NSW load, or directions) are active for NSW today — the two non-conformance notices affect QLD1 units only. The NSW-specific notice active is the constraint set CA_SYDS_59839EB2 on the NSW1-QLD1 interconnector, which limits interregional transfer support and reinforces NSW's reliance on in-region generation to meet today's demand swings, a factor likely contributing to the sharp price response to load changes.
