Regional Outlook — NSW1: Saturday 27 June 2026

The NSW spot price sits at $80.53/MWh as of 06:25 AEST, with total demand at 7,361 MW — a notably subdued level for a Sunday morning reflecting typical weekend load patterns. That current price represents a significant easing from the overnight peak, where prices ran consistently between $150–$175/MWh during the 07:20–09:10 AEST window on Saturday evening as demand climbed toward 8,900 MW. The 24-hour price history shows a clear arc: an elevated band of $108–$137/MWh through the early morning hours (roughly 11:00–17:00 AEST overnight), a midday softening toward the low-to-mid $70s as Saturday demand tapered, and a gradual return toward the $79–$88/MWh range through the afternoon and evening. The current read is broadly consistent with that late-session stabilisation.

The generation mix at 06:30 AEST is anchored by black coal at 4,727.95 MW, accounting for approximately 71% of the regional dispatch. Wind is contributing 1,057.78 MW (roughly 16%), hydro is running at 713.1 MW (11%), and gas OCGT is providing 33.45 MW of marginal cover. Solar is effectively zero at 0.01 MW, consistent with pre-dawn conditions and today's forecast of 96% cloud cover and a maximum temperature of 15.9°C. Battery discharge stands at just 0.42 MW. Renewable penetration sits at 27.11% per the latest carbon intensity reading, down from a overnight high of approximately 35% recorded around 08:00–09:00 AEST when wind output was stronger relative to coal dispatch. Carbon intensity is at 0.6402 tCO2/MWh, having drifted upward from a session low of around 0.57 tCO2/MWh as renewable share has pulled back through the evening transition.

The predispatch curve points to a gradual price lift through today's morning peak. From the current ~$80/MWh, forecasts step up to $84.22/MWh by 08:00 AEST, $90.63/MWh by 08:30, and reach $95.58/MWh at 09:00 AEST before easing back to the $84–$85/MWh range through 09:30–10:00 AEST. The morning ramp accelerates more firmly into the business window, with predispatch pointing to $110.80/MWh sustained from 18:00–21:00 AEST, peaking at $113.14/MWh around 19:00 AEST as Sunday evening heating demand drives load upward in the 11–16°C temperature range. The midday period (23:30–01:00 AEST overnight) is forecast to settle back toward $73–$79/MWh, with an isolated trough to $65.55/MWh flagged around 15:00 AEST and a brief dip to $62.24/MWh at 16:30 AEST. These shallow troughs likely reflect wind generation variability against modest weekend demand. For flexible load operators, the optimal windows are the 15:30–17:00 AEST band (avg ~$71/MWh) and the 13:30–15:30
