Regional Outlook — NSW1: Saturday 6 June 2026

The NSW spot price sits at $122.30/MWh as of 06:30 AEST, demand tracking at 7,602 MW and rising into the morning. This is elevated relative to the overnight trough — prices compressed to a floor near $13–24/MWh between roughly 01:00 and 04:00 AEST before surging sharply from 05:30 AEST as the winter morning ramp took hold. The day's price pattern is textbook June: a deep overnight valley followed by a steep climb as heating demand lifts. Prices peaked at $131.70/MWh at 17:30 AEST and again at 17:00 AEST, and the current interval is tracking close to those highs. The 24-hour average sits comfortably above $80/MWh given the sustained triple-digit pricing across the morning and early afternoon, with a brief mid-afternoon easing to the high $80s before climbing again post-18:00 AEST.

The generation mix at 06:30 AEST is dominated by black coal at 5,394 MW, followed by hydro at 907 MW, batteries discharging at 319 MW, gas CCGT at 300 MW, wind at 83 MW, gas OCGT at 24 MW, and solar contributing a minimal 25 MW — consistent with the pre-dawn interval. Total identified generation across these sources sits at approximately 7,053 MW. Renewables are contributing 18.91% of supply at this interval, a figure that has been declining steadily since the overnight period when hydro-driven renewable penetration pushed above 49% between 01:00 and 03:00 AEST. Carbon intensity stands at 0.6962 tCO2/MWh, up sharply from the overnight low of 0.4371 tCO2/MWh reached at around 13:00 AEST — the intensity curve has tracked inversely with hydro's relative share through the day. Today's clear winter conditions (8°C, 8% cloud cover, near-zero wind potential) mean solar will offer modest daytime relief but wind output is unlikely to provide material support.

Predispatch forecasts for the 07:00 AEST interval point to $118.54/MWh (most recent run at 06:01 AEST), with the 07:30 AEST interval forecast at $118.64/MWh. Earlier predispatch runs through the day showed a consistent band of $95–$120/MWh for these intervals, with the more recent runs converging toward the upper end as demand has come in firm. The load window data signals price relief emerging from approximately 08:30–09:30 AEST (23:30–00:30 UTC), where forecasts drop to the $38–$56/MWh range, and further easing to near floor prices ($1–$12/MWh) in the 10:30–13:00 AEST window — consistent with a typical Sunday low-demand pattern once the morning ramp dissipates and before solar makes any meaningful contribution.

The most operationally relevant active notice for NSW is the Directlink No. 3 Leg inter-regional transfer variation (Notice 144201), which flagged a planned outage from 1 June through 8 June — this interconnector leg is scheduled to remain out until 1600 hrs on 8 June, constraining NSW-Q
