Regional Outlook — NSW1: Friday 19 June 2026

The NSW1 spot price sits at $79/MWh as of 06:30 AEST, with demand at 7,360 MW — relatively modest for a winter Saturday morning. Tracking back through the past 24 hours, prices ranged from a low of $27.88/MWh in the early hours to intraday peaks touching $82.68/MWh during the morning ramp, with a sustained floor of around $38–$43/MWh through the overnight trough. The 24-hour average sits in the low-to-mid $60s/MWh, making the current $79/MWh print elevated relative to that baseline as the grid heads into the Saturday morning peak. The current reading is being shaped by a 12.1°C temperature in Sydney and a heating demand signal of 5.9, which is driving residential load upward even on a weekend.

The generation mix at the most recent trading interval is led by black coal at 4,683 MW, followed by wind at 1,066 MW, hydro at 597 MW, gas OCGT at 41 MW, battery discharging at 21 MW, and solar at 29 MW — the latter reflecting near-zero output at this pre-dawn hour with 0% solar potential currently. Total renewable contribution sits at 26.61%, with a carbon intensity of 0.6444 tCO2/MWh. This is the highest carbon intensity recorded across today's data, up from a overnight low of 0.4738 tCO2/MWh at 12:00 AEST when renewable penetration peaked at 44.95% — driven primarily by stronger overnight wind and a reduced coal dispatch profile. Wind at 1,066 MW is the primary renewable contributor given the absence of meaningful solar generation at this hour.

Predispatch forecasts paint a materially firmer picture for the next several hours. Prices are forecast to rise through the morning: $70.71/MWh at 07:00 AEST, $84.36/MWh by 07:30, $89.70/MWh at 08:00–08:30, and peaking at $111/MWh at the 22:30 UTC interval (08:30 AEST trading period). The midday window from approximately 22:00–23:00 UTC (08:00–09:00 AEST) shows a sustained band of $89–$96/MWh, before prices ease back toward $70–$75/MWh in the early afternoon AEST and then moderate to the high $50s during the overnight trough. The lowest forecast price window for load shifting falls between 13:00–14:30 AEST (03:00–04:30 UTC) at an average of $53.49/MWh — the optimal window for deferrable industrial or commercial load.

Two active market notices are directly relevant to NSW1 today. ORABESS1, the Orana battery storage unit in NSW, recorded non-conformance events on 16 June at -415 MW and -131 MW deviations — both resolved, but worth monitoring given battery assets are currently dispatched at only 21 MW. Separately, a planned MSATS outage is scheduled for 24 June 2026 from 13:00–17:00 AEST under CHG0108153 (Shortening the Settlement Cycle Release 1), which will interrupt market system access for settlement and metering functions
