Regional Outlook — NSW1 — Tuesday 5 May 2026

The NSW spot price sits at $134.88/MWh at 06:30 AEST, with total demand at 7,913 MW — well above the overnight trough of around 5,450 MW recorded in the early hours. Scanning the full price history, the session has been elevated since the morning ramp, with prices holding above $116/MWh for most of the business day before tracking back toward the $80–100/MWh range through the afternoon and early evening, then climbing again through the 06:00–06:30 AEST window as demand rebuilds into the evening peak. The day's high of $152.27/MWh was recorded at 18:00 AEST, indicating tight supply conditions during the morning peak. Current demand of 7,913 MW represents a significant re-escalation from the 6,550–6,750 MW range observed mid-afternoon.

The generation mix at the most recent interval (06:25 AEST equivalent) is dominated by black coal at 5,850.52 MW, hydro at 721.6 MW, wind at 106.17 MW, and solar at 28.96 MW. Gas CCGT and OCGT are both contributing 0 MW. Total identified generation sits at approximately 6,707 MW against 7,913 MW demand, with the gap accounted for by imports and any unmetered generation. Renewable penetration stands at 12.77%, down from a daytime peak near 16.86% recorded around midday when solar was contributing more meaningfully. Carbon intensity is 0.7676 tCO2/MWh, having eased slightly from the 0.7977–0.7984 tCO2/MWh readings registered during the 17:30–18:00 AEST window when renewable penetration dipped below 10%. Today's solar potential is effectively zero given the current temperature of 11.6°C and near-zero solar irradiance — any solar uplift will depend on conditions through the morning hours on Wednesday.

Predispatch forecasts for the 07:00 AEST half-hour (21:00 UTC) are clustering between $120/MWh and $134.89/MWh across recent runs, with the most recent dispatch forecast (20:01 UTC run) landing at $134.89/MWh. Earlier forecasts for that interval were as low as $109–$118/MWh, indicating that upward price pressure has been building through the afternoon as the market reassessed supply conditions. The load window data confirms a pronounced dip in prices expected through the 09:00–11:30 AEST overnight trough, with forecast prices as low as $0.01–$9.77/MWh flagged in some windows — consistent with low overnight demand and thermal baseload surplus. The morning ramp from 14:00–17:00 AEST is expected to return prices to the $60–$80/MWh range based on the load window signals.

Two market notices are directly relevant to NSW today. An active inter-regional transfer notice (MN 144047) flags an unplanned outage on Leg 3 of Directlink, with constraint set N-MBTE_1 invoked since 02:30 AEST on 5 May, restricting the N-Q-MNSP1 interconnector and reducing Queensland import capacity into NSW. Separately, a foreseeable AEMO intervention notice (MN 144048)
