Regional Outlook — NSW1: Thursday 18 June 2026
The NSW spot price sits at $64.89/MWh with total demand at 7,924 MW as of 06:25 AEST. That current price is notably softer than the evening peak period, which saw prices consistently holding around $79–$80/MWh when demand was tracking above 9,000 MW during the morning ramp. The 24-hour price profile shows a classic winter demand pattern: a sustained morning peak band from roughly 16:30–18:10 AEST in the $67–$80/MWh range, collapsing through the middle of the day to lows in the $38–$43/MWh range around 02:00–03:00 AEST, before recovering through the evening. The current reading marks the beginning of another demand build, with total load climbing from a trough of around 6,614 MW at 03:43 AEST back toward the 7,900 MW range now.
The generation mix at the 06:00 AEST trading period shows black coal at 3,716 MW, wind at 1,916 MW, hydro at 388 MW, solar at 155 MW, gas OCGT at 124 MW, battery at 0.26 MW, and gas CCGT at zero. Renewable penetration sits at 39.04% with carbon intensity at 0.532 tCO2/MWh. That intensity reading is a meaningful improvement on the 0.669 tCO2/MWh recorded during last night's peak demand period around 07:00 AEST, when renewables were contributing only 22–23% of the mix — wind output is clearly carrying the overnight and early morning generation profile while solar remains negligible in current overcast, near-zero solar potential conditions (96% cloud cover, 17°C). Tomorrow's outlook is little better on solar, with 99% average cloud cover forecast and solar potential at zero all day Friday.
Predispatch forecasts point to a firm price escalation through the morning. From the current $64.89/MWh, prices are forecast to dip briefly to $56.20/MWh at 07:00 AEST before recovering sharply: $67.30/MWh by 07:30 AEST, then climbing into the $73–$79/MWh band from 12:00 AEST through to around 19:30 AEST as demand peaks. The 09:30–10:30 AEST window is the sharpest, with forecasts of $78.59–$78.65/MWh. Overnight tonight prices are expected to fall back to $37.89–$42.54/MWh between 10:00–11:30 AEST (UTC+10), offering the best load-shifting windows of the day. Flexible demand operators should note the $37.89/MWh trough forecast at 14:00 AEST as the lowest-price window across the full 24-hour horizon.
On active market notices, two are directly relevant to NSW participants. ORABESS1 — the Orana battery in NSW — recorded two non-conformance events on 16 June, deviating by -415 MW and -131 MW respectively; while these are historical notices, they signal ongoing monitoring of that asset's dispatch compliance. A separate non-conformance for WTAHB1 (Wheat Hill wind farm, NSW) was declared on 13 June for a +134
