Regional Outlook — NSW1: Sunday 12 April 2026

The NSW1 spot price sits at $64.89/MWh as of 06:30 AEST, with total demand at 7,325 MW. Looking across the past 24 hours, prices traced a pronounced overnight trough — sustaining negative territory from around 07:00 AEST through to approximately 17:00 AEST, touching a low of -$25.50/MWh in the early hours — before recovering sharply into the morning peak, where prices briefly reached $77.15/MWh around 18:25 AEST. The current $64.89/MWh level reflects stabilisation in the post-morning-peak window, broadly in line with the $61–$65/MWh band that has dominated the past several hours.

The generation mix is dominated by black coal at 4,757.7 MW, which accounts for the bulk of regional output. Wind contributes 284.7 MW, solar 134.3 MW, and hydro 121.9 MW. Both gas CCGT and gas OCGT are at zero output. Total renewable generation — wind, solar, and hydro combined — sits at approximately 541 MW against a 7,325 MW demand base, yielding a renewable penetration of 10.21% for the current interval, down from an overnight high of around 22% when demand was lower and wind output was relatively stronger. Carbon intensity is 0.7902 tCO2/MWh, up from a 24-hour low of 0.683 tCO2/MWh recorded in the early hours when the renewable share was at its peak. The intraday intensity pattern reflects the inverse relationship between renewable penetration and demand: as Monday morning load has built, coal dispatch has risen and intensity has tracked upward accordingly.

Predispatch forecasts point to a meaningful price step-up this evening. The 07:00 AEST target interval (21:00 UTC) is forecast at $65.85/MWh in the most recent predispatch run, but earlier runs through the day were consistently projecting $79–$85/MWh for that period, with one run peaking at $98.14/MWh. The convergence toward $65–$66/MWh in the last two runs suggests the market is pricing in adequate supply cover for the early evening, though the spread across runs indicates residual uncertainty around the evening demand ramp. Load window data confirms that prices are expected to fall back into negative territory overnight from approximately 08:00 AEST onwards, with the deepest windows forecast around -$25.50/MWh between 13:00–14:00 AEST — consistent with the pattern observed over the previous 24 hours.

On market notices, the only active notice directly relevant to reserve adequacy is AEMO Market Notice 141048, which declares a Forecast Lack of Reserve Level 1 (LOR1) condition in South Australia between 01:30 and 02:00 AEST on 14 April 2026, with forecast capacity reserve of 258 MW against a requirement of 406 MW. This notice does not directly affect NSW dispatch but warrants monitoring given potential interconnector flows between SA and NSW via VIC. The earlier LOR1 for SA on 12 April (Notice 141048's predecessor, 141049) was cancelled at 13:40 AEST on 12 April. No active notices directly constrain NSW generation or transmission infrastructure today. NSW traders should note the SA LOR1 window on Tuesday
