Commodity Demand — NSW1: Saturday 13 June 2026

NSW spot sits at $70.71/MWh with demand at 6,621 MW as of 06:25 AEST, placing the region in the descending phase of its overnight trough. The price-demand relationship across today's session has been highly instructive: demand peaked near 8,924 MW around 17:35 AEST and prices held in the $84–$90/MWh band through the morning and midday, then eased progressively as demand retreated through the afternoon and evening. The correlation is tight — each 500–700 MW step down in demand from that peak has produced a corresponding $10–$15/MWh softening in the spot price, with current conditions reflecting demand now tracking roughly 2,300 MW below today's peak.

The overnight demand trough is still developing. Between approximately 11:45 AEST and 12:25 AEST, demand sat below 6,300 MW and spot fell as low as $0.98/MWh, with prices anchored below $25/MWh for the better part of three hours. Demand has since crept back to 6,621 MW as the early morning pick-up begins, and price has responded, lifting from mid-$60s to $70.71/MWh. This demand floor-to-ramp sensitivity is the key dynamic shaping the next few hours: each incremental load recovery from here pushes the dispatch stack into progressively more expensive capacity.

The forecast profile signals a pronounced step-up from around 16:00–17:00 AEST, with prices forecast to reach $91–$98/MWh in the 17:00–19:00 AEST window as the winter morning demand ramp coincides with limited solar output — cloud cover is 87% and solar potential reads zero, consistent with a fully overcast June day. The 15:00–16:30 AEST period (AEST equivalent of the 05:00–06:30 UTC forecast window) shows prices escalating from $61/MWh to $85/MWh as demand lifts toward a second daily peak. Load windows rated "good" for price-sensitive demand are concentrated between 11:00–14:00 AEST ($56–$65/MWh) and again around 02:00–03:00 AEST tomorrow, offering the lowest exposure periods for flexible loads.

One market notice warrants attention for demand-side context: the non-conformance declaration for unit WTAHB1 (134 MW, 21:50–21:55 AEST) did not materially disrupt pricing, but the active inter-regional transfer notice relating to the Blackwall–Tarong and South Pine–Tarong 275kV line outages in Queensland — now completed at 08:40 AEST — removes a constraint that had been limiting NSW–QLD flows. With those constraint sets revoked, interconnector headroom between NSW and QLD is restored, which marginally improves NSW's supply-side options during the forecast demand ramp and provides a modest dampening effect on peak price outcomes relative to what would have applied under constrained transfer conditions.
