Regional Outlook — NSW1: Sunday 7 June 2026

The NSW spot price sits at $82.92/MWh as of 06:30 AEST, with total demand at 7,520 MW — a significant step down from the morning peak, which saw prices sustain above $115/MWh from around 16:30 AEST through to 18:00 AEST with demand touching 9,461 MW at the top. Overnight prices tracked between $29–$52/MWh during the low-demand trough (roughly 23:30–14:30 AEST), so the current level reflects the early evening demand rebuild rather than any supply-side stress. The 24-hour average sits materially above that overnight trough, underpinned by those sustained triple-digit intervals across the morning and midday peak.

The generation mix at the current interval is led by black coal at 5,486 MW, followed by hydro at 878 MW, wind at 699 MW, solar at 121 MW, battery discharge at 76 MW, and gas OCGT at 24 MW. CCGT is offline. Renewables — wind, solar, and hydro combined — are contributing approximately 1,699 MW, representing 24.35% of total generation per the latest carbon data. That renewable share is notably lower than the overnight high of around 50% recorded near 12:30 AEST, when demand troughed and wind output was stronger. Carbon intensity stands at 0.665 tCO2/MWh, down from the 0.70 tCO2/MWh registered during the evening peak on Sunday but well above the overnight low of 0.437 tCO2/MWh. Today's weather profile — 8.4°C, 36% cloud cover, minimal solar potential, and low wind at 0.9 — is consistent with a winter Monday pattern: elevated heating demand through the day, limited rooftop solar contribution, and a generation mix weighted toward dispatchable plant.

Predispatch forecasts for the 07:00 AEST interval (21:00 UTC) have converged to around $83–$84/MWh across the most recent runs, with the 07:30 AEST interval forecast at approximately $98–$101/MWh. That step-up aligns with typical winter evening demand — temperatures remain below 10°C and heating demand is elevated at 9.6. Traders should note the gap between current actuals (~$83/MWh) and the predispatch signal for the next half-hour interval (~$98/MWh): if demand builds as forecast toward the 07:00–08:00 AEST window, short positions in that window carry upside risk. The daily outlook shows a maximum of 17.9°C today with average solar potential of only 11.9, reinforcing that midday price softening will be modest compared to warmer months.

The most operationally relevant active notice for NSW participants is the Forecast LOR2 in South Australia on 10 June 2026, updated under Market Notice 144206. The window has shifted to 08:30–17:00 AEST on Wednesday, with minimum reserve of 384 MW against a requirement of 571 MW — a 187 MW shortfall. AEMO is seeking a market response. While this notice is SA-specific, it has direct relevance for NSW: tighter SA conditions can constrain Heywood interconnector flows and affect VIC dispatch costs, which in turn influence NSW–VIC interconn
