Commodity Demand — NSW1: Saturday 18 July 2026

NSW spot price sits at $65.03/MWh at 06:30 AEST with demand at 7,511 MW, tracking the tail end of the overnight demand build as the region moves through the pre-dawn ramp. This follows a textbook overnight pattern: demand troughed near 6,565-6,750 MW between 02:00-04:00 AEST with prices compressed into the $30-60/MWh band (including a brief $1.26/MWh print at 04:05 AEST), before climbing steadily from ~6,900 MW at 05:00 AEST toward current levels.

The price-demand relationship is tight and non-linear today. Through the morning ramp on 18 July, each ~1,000 MW of demand growth from 7,500 MW to 9,900 MW (peak reached at 08:00-09:00 AEST) pushed prices from the $65-90/MWh range up into the $90-100/MWh band, with the tightest coupling above 9,500 MW where price sat pinned near $90.49/MWh for extended periods — indicative of a marginal generator offer cap or bid cluster at that level. The evening peak on 17 July showed far more sensitivity: demand climbing from 8,150 MW to 8,720 MW between 21:00-21:30 AEST drove prices from ~$115/MWh to spikes above $190/MWh, confirming NSW's evening ramp remains the highest-risk window for price volatility when demand accelerates quickly against a tightening supply stack.

AEMO's forecast trajectory for today points to a morning peak: forecast RRP climbs from $69.99/MWh at 07:00 AEST to $90.49/MWh by 08:00-08:30 AEST, then to $97.63/MWh at 09:00 AEST — consistent with the demand-driven pattern observed yesterday during the same window. Prices are forecast to ease through midday into the $70-90/MWh range, then soften further into the afternoon, dropping to $45-65/MWh by 16:00-18:00 AEST as demand tapers. Overnight, load-shifting windows show strong value: 01:00-06:30 AEST offers sub-$52/MWh pricing, with the cheapest window (04:30-05:30 AEST forecast) averaging $42.44/MWh, a $55/MWh saving versus peak.
