Regional Outlook — NSW1 — Friday 8 May 2026

The NSW spot price sits at $109.41/MWh as of 06:30 AEST, with demand at 7,387 MW — considerably below the daytime peak of 9,544 MW reached around 17:44 AEST. Today's price trajectory tells a clear two-act story: a prolonged period of negative and near-zero prices from roughly midnight through to 06:15 AEST (bottoming at -$8.29/MWh at 12:45 AEST UTC, or approximately 13:45 AEST), followed by a sustained elevated band through the afternoon and evening, with prices repeatedly touching $120/MWh across multiple dispatch intervals from 04:15 AEST onwards. That evening band has been sticky — over two hours of intervals settled at or near $120/MWh — and the current $109.41/MWh reading reflects only modest softening as demand eases past the post-sunset peak.

The generation mix at the latest interval is dominated by black coal at 5,281 MW, with hydro contributing 948 MW, wind at 71 MW, and solar at 64 MW. Gas — both CCGT and OCGT — is dispatched at zero. Total renewable penetration sits at 17.04%, with carbon intensity at 0.73 tCO2/MWh. This is a modest improvement from the 0.79 tCO2/MWh recorded around 07:00 AEST, when renewables were contributing just over 10%; the intraday peak renewable share of 23.19% occurred around 18:15 AEST as solar was generating at its daytime high. With solar now at 64 MW and declining toward zero as the evening progresses, renewable share will continue to compress and carbon intensity is likely to edge higher into the overnight period, consistent with the trend observed in the carbon history.

Predispatch forecasts for the 07:00 AEST half-hour (21:00 UTC) have converged firmly in the $113–$124/MWh range across the most recent runs, with the last several forecasts clustering around $113–$120/MWh. This signals the market does not expect significant relief in the near term. Forecasts for the 07:30 AEST period are thinner in the dataset but earlier runs pointed to the $84–$94/MWh range, suggesting prices may soften as overnight demand falls and the load windows — which show prices as low as $1/MWh from 09:30–10:30 AEST (23:30–00:00 UTC) — materialise. Flexible load operators and battery operators should note the structural overnight low is expected in the 09:30–12:30 AEST window, with multiple load window estimates below $10/MWh and several negative price signals in the 10:30–14:00 AEST range.

Two market notices are directly relevant to NSW. First, an inter-regional transfer limit variation (Notice 144025) remains active following an unplanned outage of the Armidale No.3 330/132 kV transformer at 15:08 AEST, which invoked constraint set N-AR_TX on the N-Q-MNSP1 interconnector — this is constraining QNI transfer capability and is a contributing factor to elevated NSW prices. Second, Notice 144066 recorded a non-conformance event for unit WTAHB1 in NSW1 at 23:
