regional nsw — NSW1

The NSW spot price sits at $134.89/MWh against total demand of 8,118 MW as of 06:30 AEST, sitting at the elevated end of today's trading range. The 24-hour price profile tells a clear story: prices collapsed into near-zero territory overnight between roughly 10:00–13:00 AEST (sub-$1/MWh on multiple intervals) before climbing sharply through the morning peak, where sustained readings above $110–120/MWh have prevailed since 15:30 AEST. The current level of $134.89/MWh reflects typical post-sunset tightening as solar generation falls away and demand builds toward the evening peak, which reached a session high of 9,708 MW around 17:40 AEST.

The generation mix is overwhelmingly coal-dependent. Black coal is producing 6,255 MW — approximately 90% of in-region generation — with hydro contributing 450 MW (6.5%), solar 92 MW (1.3%), and wind a negligible 30 MW (0.4%). Gas CCGT and OCGT are both at zero dispatch. Renewable penetration sits at just 8.38% — well below the day's best of 13.1% recorded in the early morning — and has been trending lower through the afternoon and evening as solar output extinguishes. Carbon intensity is 0.8063 tCO2/MWh, consistent with coal's heavy dominance and broadly in line with the day's range of 0.78–0.83 tCO2/MWh. There is no meaningful decarbonisation signal in today's dispatch.

Predispatch forecasts for the 08:00 AEST trading period point to prices in the $107–115/MWh range, with the most recent runs converging around $109–110/MWh. This suggests modest easing from the current $134.89/MWh as overnight demand softens, though prices are expected to hold well above $100/MWh through the early hours. Load-shifting windows rated "excellent" emerge from around 09:00–10:30 AEST, with forecast prices dropping to $10–38/MWh — a saving of roughly $97–125/MWh against current levels — consistent with the overnight solar and low-demand trough pattern observed today.

Two market notices are directly relevant. AEMO earlier today reclassified the Bannaby–Mt Piper 5A6 and 5A7 500 kV double-circuit as a credible contingency event due to lightning activity, invoking constraint set N-5A6+5A7_N-2 which binds the NSW1-QLD1 and VIC1-NSW1 interconnectors on the left-hand side — this would have tightened available import capacity into NSW during the afternoon peak. That reclassification was subsequently cancelled at 19:34 AEST once lightning activity cleared. A separate active reclassification notice covers the Kamerunga–Barron Gorge double-circuit in QLD1, which remains in force as a credible contingency from 06:11 AEST. Multiple intervals across the early morning trading day are also subject to ongoing AEMO Manifestly Incorrect Inputs review, though confirmed intervals so far have returned prices unchanged.
