regional nsw — NSW1

NSW spot is at $135.33/MWh as of 16:25 AEST, up sharply from the morning trough of $62–$65/MWh and tracking well above the overnight average of roughly $85–$100/MWh seen through the 22:00–06:00 AEST window. The price spike is coinciding with demand ramping hard into the late-afternoon peak, with total demand at 8,312 MW and climbing — yesterday's equivalent period reached above 9,100 MW, so further upward pressure is likely in the 17:00–19:00 AEST window. The intraday high of $144.32/MWh was recorded at 16:10 AEST, signalling the market is already testing elevated territory ahead of the evening peak.

The generation mix is heavily coal-dominated. Black coal is carrying 6,277 MW — approximately 85% of visible dispatch — with hydro contributing 862 MW (12%) providing the only meaningful flexible response. Solar is at just 116 MW and wind at 33 MW, together representing under 2% of dispatch at this hour as solar output fades. Gas CCGT and OCGT are both sitting at zero, leaving the grid with limited peaking capacity beyond hydro to absorb any demand surge or unexpected outage. Renewable penetration was 9.89% at the last carbon interval, down significantly from an intraday peak of ~19% recorded around 07:00–07:30 AEST when solar was contributing more meaningfully.

Carbon intensity is 0.7914 tCO2/MWh, consistent with a coal-heavy dispatch profile. The overnight and morning periods saw intensity dip to a low of 0.7129 tCO2/MWh when renewable share approached 19% — sustainability managers targeting low-carbon consumption windows should note that opportunity has closed for today. The trajectory from 10:30 AEST onward shows intensity firming back above 0.79–0.84 tCO2/MWh as solar ramped down and coal held firm. No improvement is likely until solar returns tomorrow morning from approximately 07:00 AEST.

Predispatch forecasts point to prices easing from the current spike toward the $104.89/MWh range through the evening, with load window signals clustering around $66–$80/MWh from 08:30–09:00 AEST tomorrow — the next credible low-price, fair-quality window. No active market notices are recorded for NSW1. Grid stress is scored at 72.7/100, market conditions at 41.7/100, and renewable penetration score at 16.1/100 — all consistent with a high-coal, peak-demand afternoon. Traders should watch interconnector flows and hydro dispatch closely; with gas offline, hydro is the only lever available if coal units trip ahead of the evening peak.
