Regional Outlook — NSW1: Sunday 14 June 2026

The NSW1 spot price sits at $88.88/MWh as of 06:25 AEST, with total demand at 7,859 MW. Reviewing the price history, the region has run largely in the $75–$97/MWh band through the morning peak, with a brief spike to $111/MWh at 15:40 AEST during the overnight demand surge that pushed load above 9,300 MW — the highest point in the dataset. Prices then eased through the afternoon and early evening as demand retreated, before climbing back toward the $88–$90/MWh range as demand rebuilds through the current interval. The 24-hour volume-weighted average across visible intervals sits in the low-to-mid $70s/MWh, placing the current print notably above that average and reflecting a demand-driven re-escalation heading into the Monday morning build.

The generation mix is dominated by black coal at 5,196 MW, followed by wind at 1,115 MW, hydro at 912 MW, battery discharge at 64 MW, gas OCGT at 43 MW, and solar at 29 MW. Gas CCGT is currently offline at 0 MW. Total metered output across these fuel types is approximately 7,357 MW, consistent with the reported demand figure when imports are accounted for. Renewables — wind, solar, hydro, and battery combined — are contributing approximately 2,120 MW, or roughly 28.8% of the grid mix, which aligns precisely with the latest renewable penetration reading. Carbon intensity sits at 0.6252 tCO2/MWh, a slight uptick from the 0.574–0.588 tCO2/MWh range recorded through the mid-afternoon period (14:00–18:00 AEST) when renewable penetration peaked above 33%.

Predispatch forecasts point to further upward pressure in the near term, with a step to $98.15/MWh forecast for 07:30 AEST before easing back to $89.70/MWh at 08:00 AEST and $87.17/MWh at 08:30 AEST. Beyond that, prices are forecast to fall sharply through the overnight period — dropping to $56.06/MWh by 09:00 AEST, trending further down to a low of $42.75/MWh around 14:00–14:30 AEST, then recovering to $61–$82/MWh through the morning peak tomorrow. Flexible load operators have a clear overnight demand-shifting window between approximately 10:30 AEST tonight and 15:00 AEST tomorrow, where forecast prices are consistently in the $42–$58/MWh range — a saving of $43–$55/MWh against the current price.

On market notices, the most operationally relevant item for NSW1 is a non-conformance declaration for unit WTAHB1 (a wind unit), which deviated by 134 MW for a brief five-minute window on 13 June — now resolved. An active inter-regional transfer notice remains in place regarding automated constraint set CA_BRIS_593C7214 on the N-Q-MNSP1 interconnector, which could influence northward flows depending on QLD system security conditions. Weather today is clear with 9% cloud cover and 15.4°C, but tomorrow's outlook carries 81% average
