Regional Outlook — NSW1: Wednesday 13 May 2026

The NSW spot price sits at $97.34/MWh as of 06:35 AEST, with demand at 7,913 MW and rising. This is consistent with the evening ramp now underway — the price trajectory through the session shows a clear trough overnight (sub-$30/MWh between roughly 09:30–10:00 AEST) before climbing steadily through the morning peak ($111–$119/MWh around 07:15–08:15 AEST), easing through midday, and now re-accelerating into the evening demand build. The 24-hour volume-weighted average across the price history sits in the mid-$70s/MWh, placing the current $97.34/MWh materially above that baseline and tracking toward a firm evening peak. Predispatch for the 07:00 AEST half-hour is forecasting $97.67/MWh, and the 07:30 AEST target is consistently priced at $97.67/MWh across multiple forecast runs — indicating the market has high confidence in prices holding near current levels into the next trading period.

Black coal dominates the generation mix at 5,849 MW, accounting for roughly 70% of the 8,284 MW total dispatched output. Wind is the second-largest contributor at 1,408 MW (17%), followed by hydro at 695 MW (8.4%), battery storage dispatching 173 MW (2.1%), and solar contributing 132 MW (1.6%) — with only 27 MW of gas OCGT online and CCGT at zero. Renewable penetration sits at 29.07% at the most recent interval, which is consistent with the late-evening position as solar generation fades. Carbon intensity is 0.6235 tCO2/MWh, above the daytime lows of 0.46–0.48 tCO2/MWh recorded overnight when wind penetration was peaking above 47%. The grid stress score is elevated at 89.6/100, reflecting tightening supply conditions as demand climbs.

The most directly relevant active notice for NSW is the 9 May network augmentation confirming commissioning of the Wagga–Dinawan 330 kV dual circuit lines and Dinawan 330 kV buses. This is a structural positive for NSW transmission capacity, particularly for flows between the south-west and the broader transmission backbone. The Directlink No.3 leg outage (notice 144047) remains active, constraining the N-Q-MNSP1 interconnector and limiting NSW–QLD transfer capability on that path — relevant context for any cross-border position. The MT PASA reserve notice (144070) identifies no Low Reserve Conditions across the NEM for the outlook period.

For flexible load operators, the optimal dispatch windows are concentrated between 08:30–11:30 AEST tonight, where predispatch pricing drops to the $10–$24/MWh range across multiple half-hours. Tomorrow's weather outlook — a maximum of 19.1°C with 57% average cloud cover and moderate solar potential of 4.4 — suggests a standard autumn demand profile with a modest solar shoulder easing midday prices. With overnight wind potential rated low at 0.9, the carbon intensity and price support from thermal generation are likely to persist through Friday's morning peak, with the potential for the overnight price softening to be shallower than tonight's if wind underperforms.
