Commodity Demand — NSW1: Monday 14 September 2026
NSW spot price sits at $82.84/MWh at 06:30 AEST, with demand at 7,396 MW and climbing through the morning ramp. This continues an overnight pattern where price tracked demand closely: prices fell to negative territory ($-8.66/MWh) between 05:00-06:00 AEST as demand bottomed near 5,000-5,300 MW in the early hours, then rebounded sharply as demand rose back through 6,000-7,000 MW. The current 06:30 print of $82.84/MWh compares with $57.44/MWh at the same time yesterday, on similar demand — indicating today's morning ramp is pricing tighter than the prior session despite comparable load levels.
Demand is set to keep climbing through the morning peak. AEMO's forecast curve shows price rising to $77-84/MWh by 08:00-09:30 AEST as the morning ramp completes, before easing slightly through midday. The more significant move is forecast for the afternoon: prices lift from around $84/MWh at 09:30 to a peak of $102.97/MWh at 13:00 AEST, before easing back to $75.96/MWh by 18:00 AEST. This afternoon peak is notably sharper than typical morning-driven demand patterns, suggesting tightening supply margins or reduced renewable output are compounding demand-side pressure into early afternoon.
Generation mix at the current interval shows black coal supplying 5,121 MW of NSW's load, with wind at 453 MW, hydro at 290 MW, battery discharge at 149 MW, and solar just beginning to contribute at 147 MW as the sun rises. Renewable penetration sits at 16.75%, with carbon intensity at 0.731 tCO2/MWh — both reflecting the low-wind, pre-solar conditions typical of this time of day. Today's weather outlook shows moderate solar potential (33.8% average) and modest wind (9.4% average), which should support increased renewable output past mid-morning, but the afternoon price spike to $103/MWh suggests the market is pricing supply tightness that renewables alone won't fully offset.
On demand-side factors, no NSW-specific demand response or minimum system load notices are active today — those interventions are concentrated in SA, tied to voltage control directions issued to AGL's Torrens Island units. NSW's own grid notice relates to the Eraring-Newcastle 330kV line, which returned to service yesterday afternoon, removing that transmission constraint from today's dispatch. For load-shifting decisions, the AEMO forecast identifies negative pricing windows from 00:00-05:00 AEST tomorrow (peaking at -$13.14/MWh around 04:30), reinforcing that overnight remains the low-cost window while today's 12:00-14:00 AEST window carries the highest price risk of the trading day.
