Commodity Demand — NSW1: Tuesday 19 May 2026
NSW spot is at $67.08/MWh with demand sitting at 7,943.7 MW as of 06:25 AEST — well below the intraday peak of 9,840 MW recorded around 17:55 AEST and consistent with the post-evening-ramp demand profile typical of a mid-May weeknight. The price-demand relationship across today's data is pronounced: when demand climbed through the morning ramp from roughly 8,200 MW at 13:30 AEST to its 9,840 MW peak by 17:55 AEST, prices held in the $76–$100/MWh band with occasional spikes to $130.98/MWh at 16:40 AEST. As demand retreated through the afternoon and into the evening, prices compressed back toward the $56–$67/MWh floor, confirming the stack is relatively flat in the 7,500–8,200 MW range but responsive above 9,000 MW.
The evening ramp is now underway. Demand has risen from a low of 6,537 MW at 04:55 AEST to 7,943.7 MW currently, with prices tracking upward from sub-$60/MWh territory around 03:00–04:00 AEST. The current $67.08/MWh print is softer than the $85–$87/MWh seen 30 minutes ago as demand briefly lifted above 7,800 MW, suggesting some price volatility as the market navigates the steepening demand curve. The generation mix at 06:00 AEST shows black coal at 5,009 MW, wind at 851 MW, hydro at 640 MW, battery dispatch at 154 MW, and solar at 144 MW, with both gas sources offline — a configuration that leaves the upper end of the dispatch stack exposed to demand pressure with limited flexible thermal response.
Forward forecasts for the 07:00 AEST and 07:30 AEST intervals are priced at $84.79–$91.70/MWh, consistent with demand approaching and potentially exceeding 8,500 MW as the morning workday ramp builds. Today's weather — a maximum of 17.9°C with minimal cloud cover and moderate wind — points to moderate heating demand through the morning and limited solar contribution until later in the day. With no Low Reserve Conditions declared for NSW in the current MT PASA, supply adequacy is not a concern, but the absence of gas-fired generation means any demand overshoot above 9,000 MW will test hydro and battery availability before higher-cost plant is required. Traders should watch the 08:00–09:00 AEST window closely; yesterday's equivalent period held $76–$88/MWh with demand between 9,480 and 9,840 MW, and today's trajectory points to a similar test.
