Commodity Demand — NSW1: Friday 26 June 2026

NSW spot sits at $120/MWh with demand at 7,959 MW as of 06:25 AEST — well off the winter morning peak of 10,928 MW reached around 17:55 AEST, which drove prices into the $175–$213/MWh band for several hours. The correlation between demand and price through today's data is clear: every sustained move above 10,000 MW has produced prices at or above $175/MWh, with brief spikes to $191–$221/MWh at demand shoulders near 10,243 MW and 9,790 MW respectively. The current demand level sits in a mid-range trough consistent with late-evening conditions, and pricing has responded accordingly, easing back toward the $110–$124/MWh corridor that characterised the post-peak unwind from around 22:20 AEST onwards.

The forecast trajectory is the key price driver for the rest of today. Prices are expected to lift from the current $120/MWh through $149/MWh at 07:00 AEST, then sustain $175/MWh from 07:30 through to at least 10:30 AEST as Saturday morning heating demand builds into a second winter peak. The forecast peaks at $229/MWh at 17:00 AEST and $222/MWh at 19:30 AEST — both consistent with a repeat of the demand-driven pressure seen during today's morning peak. With today's maximum temperature forecast at just 14.6°C and 94% cloud cover suppressing any solar contribution, space heating load is likely to underpin demand solidly through both the morning and early-evening windows.

The generation mix at 06:30 AEST shows black coal at 5,801 MW, hydro at 1,135 MW, and wind at 1,073 MW against negligible solar output. With solar potential effectively zero tonight and forecast to remain weak through Saturday under near-total cloud cover, there is no midday price relief from solar injection that might otherwise soften the demand-price relationship. This tightens the link between thermal dispatch costs and spot price outcomes across the full morning peak window. Wind at 1,073 MW provides some supply-side buffer, but at 27.45% renewables penetration the grid remains heavily reliant on dispatchable plant to cover peak load, keeping the price floor elevated relative to lower-demand overnight periods.

Flexible load operators should note the forecast price relief window between 14:00 and 17:00 AEST, where the forward curve drops to $99–$109/MWh as demand eases through the middle of the afternoon — a differential of $120–$130/MWh against the morning and evening peaks. The active Buronga 220 kV isolator constraint (N-BU_7118) on the VIC1-NSW1 interconnector remains in place and continues to limit import capacity from Victoria, reducing the market's ability to source lower-cost supply inter-regionally during peak periods.
