Regional Outlook — NSW1: Tuesday 25 August 2026
NSW spot price sits at $110.96/MWh as of 06:30 AEST, with total demand at 8,196 MW. Prices have been climbing through the overnight period, having troughed near $42-$65/MWh in Monday evening trade before grinding higher through the early hours — peaking sharply at $185.51/MWh at 05:15 AEST during the morning demand ramp, when demand pushed past 10,280 MW. The current price reflects a pullback from that morning peak but remains elevated relative to the $85-95/MWh band seen a day earlier, consistent with tightening supply margins as the market moves through the morning peak.
Generation mix is dominated by black coal at 6,088 MW, comfortably the largest contributor, followed by hydro at 714 MW, battery storage at 363 MW, wind at 308 MW, gas OCGT at 155 MW, and solar at 93 MW — solar output remains minimal given the early hour and 30% cloud cover. Renewable penetration sits at 19.13%, having fallen from an overnight high near 43% around midnight as wind and hydro contributions eased and coal-fired output picked up load. Carbon intensity has risen in step, now at 0.707 tCO2/MWh, up from a low of 0.501 tCO2/MWh around 23:30 yesterday, tracking the inverse relationship with renewable share typical of the overnight-to-morning transition.
Predispatch forecasts show prices holding in the $23-$120/MWh range overnight before firming again. Expect a trough near $10-$24/MWh between 15:30 and 16:00 AEST as demand eases, followed by a steady climb into the evening, with forecasts pointing to $101-$129/MWh through the afternoon peak between 12:00 and 17:00 AEST. Load-shifting windows show the best value overnight, with $11-24/MWh pricing between 01:00 and 06:30 AEST offering savings of over $100/MWh versus today's peak — a strong signal for flexible load and battery charging strategies.
One active notice affects NSW directly: AEMO declared unit VP6 non-conforming under clause 3.8.23 for a brief window from 05:45 to 05:50 AEST, involving a -21 MW deviation under constraint NC-N_VP6. No other NSW-specific network or intervention notices are currently active; recent inter-regional transfer and contingency reclassification notices relate to VIC1, TAS1 and SA1 and carry no direct NSW impact. Weather today shows mild conditions (13-18°C), moderate cloud cover (67% average), and modest wind potential (6.6%), suggesting renewable output will stay constrained through the day, keeping coal generation as the primary swing supplier.
