Commodity Demand — NSW1: Wednesday 12 August 2026
NSW demand sits at 9,082 MW at 06:25 AEST, up sharply from the overnight trough of 6,692 MW, and spot price has lifted to $96.62/MWh alongside it. The pattern through the last 24 hours confirms tight demand-price coupling: overnight troughs near 6,700-7,000 MW held price in the $23-45/MWh band, while the evening peak on 12 August pushed demand to 10,824 MW and price spiked to $183.64/MWh in a single interval. That elasticity — roughly $15-20/MWh of price movement per 1,000 MW of demand swing in the shoulder bands, steepening sharply above 10,000 MW — is the key number for today's trading.
This morning's ramp mirrors that historical pattern. Demand has climbed from 7,762 MW at 07:55 AEST equivalent (23:55 prior day UTC) through to over 9,000 MW now, tracking the typical NSW morning ramp as heating load (7.9 heating-demand index, 10.1°C current temperature) combines with commercial load pickup. AEMO's forecast has price rising further from here: $97.55/MWh by 07:00 AEST, climbing to $109.96/MWh by 07:30 AEST, and a sharp escalation to $128.73/MWh at 08:00 AEST. The forecast curve then shows a pronounced late-morning spike, with price reaching $143.90/MWh at both 09:30 and 11:00-11:30 AEST — consistent with the demand peak typically observed between 17:30 and 20:00 AEST settlement times (corresponding to 07:30-10:00 AEST market time), when NSW commercial and industrial load stacks on top of residual morning heating demand.
Generation mix at the last interval shows black coal carrying 5,915 MW of the load, with wind contributing 1,014 MW, hydro 783 MW, and batteries discharging 541 MW — renewable penetration sits at 28.89% with carbon intensity at 0.6247 tCO2/MWh, up from overnight lows near 0.41-0.43 tCO2/MWh when demand and price were both weaker. Wind potential today is muted at 7.7% and solar potential negligible given 0% cloud cover but low sun angle, meaning the midday price relief seen yesterday (dropping to $65-73/MWh between 12:30 and 18:00 AEST as solar ramped) may be less pronounced today given today's forecast average solar potential of just 23.3%.
On the demand-side notices: the Liddell-Tomago 330kV line outage that had constrained NSW transfer capacity was returned to service on 10 August, removing that constraint on interconnector flows. No new NSW-specific reserve or intervention notices are active today, though the standing MTPASA reserve notice remains focused on South Australia's 2027-28 outlook, not an immediate NSW factor. Traders should watch the 08:00-11:30 AEST window most closely — AEMO's own forecast trajectory implies this is where today's price risk is concentrated, with demand likely to test the 10,500-11,000 MW range seen yesterday afternoon.
