Regional Outlook — NSW1: Friday 5 June 2026

The NSW spot price sits at $92.72/MWh at 06:25 AEST, with total demand at 7,743 MW — materially lower than the evening peak of around 10,261 MW reached during the 18:45 AEST dispatch interval. Prices tracked in the $80–$109/MWh band through the morning peak before easing through the afternoon, then rebounding from the ~$70/MWh floor seen between 14:00–17:00 AEST as demand climbs again through the evening. The 24-hour price average sits in the mid-$80s/MWh range, placing the current dispatch interval slightly above that trend as the post-sunset demand ramp tightens supply margins.

The current generation mix (as at the 06:30 AEST trading interval) is dominated by black coal at 5,338 MW, followed by hydro at 807 MW, wind at 241 MW, battery discharge at 65 MW, solar at 13 MW, and gas OCGT at 19 MW. Gas CCGT is offline. Renewables — wind, solar, and hydro combined — account for 17.37% of generation at the latest carbon interval, a significant step down from the 44–46% renewable penetration recorded during the low-demand overnight window between 00:30 and 02:00 AEST when coal dispatch eased. Carbon intensity sits at 0.7264 tCO2/MWh, consistent with the elevated range that has prevailed since midday as coal dispatch increased to meet demand and solar output wound down with the winter sun. Today's clear sky conditions (1% cloud cover, 8.9°C) and low wind potential (6.2) suggest wind output is unlikely to provide significant relief during the coming morning peak, though the daily outlook shows a maximum of 17.7°C — moderate heating demand that will keep the morning ramp in play but is unlikely to push demand to the extreme peaks seen on colder days.

Predispatch forecasts for the 07:00 AEST interval (21:00 UTC) have converged in a $90–$96/MWh range across runs issued between 13:00 and 20:00 AEST, with the most recent runs (20:01 AEST) at $95.53/MWh and the 21:30 AEST target interval forecasting $94–$98/MWh in the available runs. This signals the market expects prices to hold firm through the early-morning period before the weekend load profile — typically softer than weekday — allows some easing. Load window data confirms off-peak pricing well under $35/MWh is expected from approximately 09:00 AEST today (23:00 UTC), dropping as low as sub-$1/MWh in the 11:00–13:30 AEST window, consistent with a Saturday midday trough when coal must run at minimum load against limited demand.

Two market notices are directly relevant to NSW today. The Directlink No. 3 Leg interconnector returned to service on 5 June following a planned outage scheduled through 8 June, revoking constraint set N-MBTE_1 and restoring full NSW–QLD transfer capacity on that cable. Separately, the Koorangie–Wemen 220 kV line in Victoria returned to service at 19:20 AEST yesterday, revoking constraint set V-KOWE and
