Regional Outlook — NSW1: Wednesday 3 June 2026

The NSW spot price sits at $71.40/MWh as of 06:25 AEST, with total demand at 8,197 MW and rising through the early-morning ramp. That current price is materially above the overnight trough — prices dipped into negative territory between roughly 13:15 and 15:25 AEST, bottoming at -$5.01/MWh around 13:20 AEST before the morning demand ramp drove a sharp recovery through the $60–$78/MWh range from 18:30 onward. The session high of $78.39/MWh printed at 18:50 AEST. The 24-hour price average across the visible history sits in the low-to-mid $40s/MWh, meaning the current price represents a significant premium to the overnight mean — consistent with winter morning heating demand building.

The generation mix at the most recent trading interval (06:00 AEST) shows black coal dominating at 4,408.87 MW, followed by wind at 2,035.22 MW, hydro at 416.90 MW, battery discharging at 224.51 MW, solar at 99.84 MW, and gas OCGT contributing a minor 21.11 MW. Gas CCGT sits at zero. Total grid-connected generation across these fuel types sums to approximately 7,206 MW, with the balance met via imports. Renewables — wind, solar, and hydro combined — are contributing approximately 2,552 MW, or around 35% of grid-connected generation. The latest carbon intensity reads 0.5403 tCO2/MWh with renewable penetration at 38.53%, a notable step down from the overnight minimum of 0.3402 tCO2/MWh (61.3% renewable) recorded around 13:00–13:30 AEST when wind output was elevated and demand was low. Carbon intensity has trended upward since that overnight low as demand climbed and the thermal-to-renewable ratio shifted with the morning peak load profile.

Predispatch forecasts for the 07:00 AEST half-hour (21:00 UTC) are converging tightly around $69.37/MWh in the most recent run, down from earlier forecasts of $72–$79/MWh issued during the morning. The 07:30 AEST half-hour (21:30 UTC) is forecast at $75.31/MWh in the latest run, with multiple prior forecasts clustering around $75.34–$75.85/MWh — indicating confidence in a modest price step-up into that interval as demand continues to build. Load-shifting windows rated "excellent" are concentrated from 09:00–12:30 AEST (00:00–02:30 UTC) where forecast prices fall to the $10–$24/MWh range, consistent with last night's overnight pattern repeating.

The most operationally relevant active notice for NSW is the contingency reclassification on the Bayswater–Mt Piper No.5A3 500 kV and Wollar–Mt Piper No.5A5 500 kV lines (Notice 144193), which were reclassified as a credible contingency due to lightning activity and subsequently cancelled on 2 June — those lines have reverted to non-credible status with no constraint sets currently invoked. A prior notice (144192) also cleared
