Regional Outlook — NSW1: Friday 12 June 2026

The NSW spot price sits at $53.73/MWh at 06:30 AEST, with total demand at 7,114 MW — well below the morning peak of 9,502 MW recorded around 17:30 AEST. Over the past 24 hours, prices tracked a clear winter profile: a sustained band of $79–$99/MWh through the 06:00–08:00 AEST morning peak, easing through the day to a low of $38.51/MWh in the 02:00–03:00 AEST window, with a brief $111/MWh spike at 11:35 AEST. The current $53.73/MWh sits below the approximate 24-hour average of around $63–65/MWh, reflecting demand settling from its overnight-to-morning ramp.

The current generation mix at 06:30 AEST totals approximately 6,278 MW of metered output across reported fuel types. Black coal dominates at 4,308 MW (68.6% of mix), followed by wind at 1,145 MW (18.2%), hydro at 449 MW (7.1%), battery dispatch at 163 MW (2.6%), solar at 169 MW (2.7%), and gas OCGT at 46 MW (0.7%). Gas CCGT is offline. Renewable penetration — wind, solar, and hydro combined — sits at 30.7% per AEMO's latest carbon data, up from a daytime trough near 19% during the high-demand morning peak. Carbon intensity is 0.6085 tCO2/MWh, improving from a 24-hour high of 0.7071 tCO2/MWh at the start of the period. Weather conditions are overcast with 100% cloud cover and a temperature of 12.9°C, keeping solar potential at zero and wind potential low at 0.4 — wind output is accordingly modest relative to installed capacity.

Predispatch forecasts signal a sharply defined price trajectory today. From the current $53.73/MWh, prices are forecast to ease further through the overnight trough to a floor of $8.73/MWh at 13:30 AEST and $11.30/MWh across the 11:30–12:00 AEST window, presenting a deep off-peak that battery and pumped hydro operators will be watching closely. The morning ramp is forecast to be steep: prices climb to $81.94/MWh by 16:00 AEST, reaching $89.70/MWh across the 18:00–20:00 AEST block and briefly touching $97.67/MWh at 23:00–23:30 AEST. The spread between the overnight floor (~$8.73/MWh) and the daytime peak (~$97.67/MWh) represents a $88.94/MWh arbitrage window — significant for dispatchable storage assets. Tomorrow's outlook is marginally more solar-favourable with a forecast maximum of 20.4°C and average solar potential of 2.1, but cloud cover remains at 93%, limiting generation upside.

Three active AEMO market notices are relevant. Prices for the 03:00 and 03:05 AEST intervals on 13 June are currently subject to review under clause 3.9.2B of the
