Commodity Demand — NSW1: Friday 14 August 2026
NSW spot price sits at $109.96/MWh at 06:25 AEST with demand at 8,023 MW, easing from the overnight evening peak but still elevated against a backdrop of a sharp morning demand ramp. Demand climbed from a low of roughly 5,730 MW around 03:20 AEST to over 10,000 MW by 08:00 AEST — a swing of more than 4,300 MW in under five hours — and price tracked this closely, spiking from single digits and even briefly negative (-$2.00/MWh at 03:20 AEST) to a peak of $182.00/MWh at 08:00 AEST. This morning ramp reflects typical winter demand behaviour: cold overnight temperatures (10.2°C, heating demand reading of 7.8) combined with minimal solar output before sunrise pushed the system toward thermal generation, with black coal supplying 5,948 MW of the current 7,404 MW generation mix versus just 53 MW of solar.
Price sensitivity to demand is pronounced through the shoulder periods. Between 06:00 and 08:00 AEST, each roughly 100 MW increment in demand corresponded to $5-10/MWh price increases as the market moved up the supply curve, peaking at $182.00/MWh when demand hit 10,022 MW. Since that morning peak, demand has eased back to the current 8,023 MW range through the middle of the day, and prices have moderated in step, trading between $85-120/MWh for most of the afternoon and evening. The pattern confirms NSW's demand-price relationship remains tight during ramp periods, with limited headroom before thermal and peaking plant are dispatched at higher marginal cost.
Looking at today's remaining trajectory, AEMO's forecast points to a further easing overnight, with forecast prices dropping to the $27-43/MWh range between 01:00 and 06:00 AEST tomorrow as demand falls toward typical overnight troughs. The identified low-demand windows (00:00-06:00 AEST) show average prices of $33-43/MWh, consistent with minimal load and available baseload capacity. Renewable penetration is currently modest at 19.12%, with wind contributing 495 MW and battery output at 99 MW, reflecting today's low wind potential (0.8 currently, rising only to 3.7 average tomorrow) and overcast conditions (72% cloud cover).
No specific demand-side notices are active for NSW today — the market notices reference an SA Murraylink control issue and a completed NSW transmission line return to service (Liddell-Tomago 330kV, back in service since 10 August), neither of which materially constrains NSW supply currently. With mild forecast temperatures (10.5-16.4°C tomorrow) and no extreme heat or cold signals in the seven-day outlook, demand is expected to follow a typical weekend shape — a moderate morning ramp already largely priced in, followed by afternoon easing and a modest evening uptick, without the risk of sustained price spikes seen on stronger demand days.
