regional nsw — NSW1

The NSW spot price sits at $71.40/MWh as of 06:30 AEST, with total demand at 6,339 MW — a Sunday morning figure well below the 8,000+ MW peak recorded around 17:00–18:00 AEST yesterday. Price has been broadly stable in the $64–$81/MWh band through the daylight and evening hours, aside from an extended run of negative prices overnight between roughly 22:30 and 05:15 AEST when demand fell below 5,000 MW and supply surplus pushed the RRP as low as -$23.53/MWh. The 24-hour price profile reflects a classic Sunday demand shape: soft overnight troughs, a firm morning ramp from 06:00 AEST, and a midday plateau before afternoon easing.

Black coal dominates the generation mix, producing 4,329 MW (approximately 68% of in-region output at the latest interval). Wind is contributing 437 MW (roughly 7%), hydro 197 MW (3%), while solar output is zero — consistent with a post-sunset reading. Gas CCGT and OCGT are both at zero dispatch. Renewable penetration sits at 12.8% at the current interval, which is materially lower than the overnight highs of 21–22% seen between midnight and 04:00 AEST when demand was at its nadir and wind remained active. Carbon intensity is 0.7674 tCO2/MWh, broadly in line with the daytime range of 0.75–0.78 tCO2/MWh and elevated compared to overnight readings that dipped to 0.69 tCO2/MWh when renewable share was higher relative to total demand.

Predispatch forecasts for the next two intervals (07:00 and 07:30 AEST, i.e. 21:00 and 21:30 UTC) point to prices in the $57–$59/MWh range, a moderate step down from the current $71.40/MWh. The forward load window data then shows prices turning sharply negative from approximately 08:00 AEST onward — with consensus estimates clustering around -$3 to -$10/MWh through the 08:00–09:00 AEST window, deepening to -$25 to -$55/MWh through midday and into early afternoon as solar generation is expected to ramp strongly. This is the characteristic Sunday shoulder-to-solar-saturation price profile for NSW in autumn. Flexible loads with the ability to shift consumption into the 09:00–15:00 AEST window face a highly favourable price signal today.

The active market notices in the feed are all contingency reclassifications relating to Tasmanian and Victorian transmission lines triggered by lightning activity over the past 24–48 hours — none directly constrain NSW generation or interconnector flows at this time. The most operationally relevant notice for NSW was the negative settlement residue event on the NSW-to-VIC interconnector (NRM_NSW1_VIC1), which was active around 19:00–19:45 AEST yesterday before being cancelled. That constraint has cleared and there is no equivalent notice currently active. A non-conformance event for NESBESS1 (a NSW battery) on 10 April was a brief 15-minute deviation and carries no ongoing operational significance. No network limitations specific to NSW1 are active in the current notice set
