Regional Outlook — NSW1 — Sunday 10 May 2026

The NSW spot price sits at $96.81/MWh as of 06:30 AEST, with total demand at 7,812.6 MW. This is broadly consistent with the morning peak band that has persisted since around 17:00 AEST, where prices ranged from $76.99 to $107.33/MWh. The overnight trough was pronounced — prices dropped as low as $23.88/MWh between 10:00 and 12:00 AEST — before climbing sharply through the pre-dawn ramp. The 24-hour average across the full price history sits in the mid-$70s/MWh, meaning the current interval is running approximately $20–25/MWh above that average, consistent with a standard weekday morning peak profile now playing out on a Monday.

The generation mix is led by black coal at 5,463.2 MW, followed by hydro at 1,039.4 MW, wind at 175.6 MW, and solar at 100.82 MW. Gas CCGT and OCGT are both offline at this interval. Total renewable contribution sits at 19.41%, which aligns with the carbon intensity reading of 0.7092 tCO2/MWh — the lowest point recorded over the past 24 hours. Carbon intensity peaked at 0.8277 tCO2/MWh around 15:30 AEST when overnight renewable penetration was at its lowest (below 6%), and has since improved progressively as wind and solar output increased through the morning. With 77% cloud cover and minimal solar potential reported for the current hour, today's solar contribution is near its ceiling for this time of day in May; the daily outlook shows clearing conditions with an average solar potential of 11.9 for Monday, which should lift renewable penetration modestly through midday.

Predispatch forecasts for the 07:00 AEST half-hour (21:00 UTC) show price estimates ranging from $83.93 to $96.69/MWh across recent forecast runs, with the most recent run at 06:01 AEST pointing to $90.48/MWh. The 07:30 AEST (21:30 UTC) forecasts are tracking slightly higher, with several recent runs printing between $88.07 and $105.64/MWh, indicating some upside uncertainty as demand continues to build. Load window data confirms the price trough opportunity shifts to the 08:30–09:30 AEST window (22:30–23:30 UTC), with forecast prices in the $42–$56/MWh range — well below current levels and flagged as "excellent" to "good" quality shifting windows for flexible load operators.

The one active market notice directly relevant to NSW infrastructure is the inter-regional transfer notice (144047) flagging an unplanned outage of the Directlink No. 3 leg, which has constrained the N-Q-MNSP1 interconnector via constraint set N-MBTE_1 since 5 May. A separate inter-regional notice (144064) also notes the Armidale No.3 330/132 kV transformer unplanned outage from 8 May, with constraint set N-AR_TX active on the N-Q-MNSP1 interconnector. Both notices remain active and traders should note that QNI transfer capacity into NSW remains reduced, limiting the ability to import from Queensland to soften price peaks. The
