Regional Outlook — NSW1: Saturday 16 May 2026

The NSW spot price sits at $98.14/MWh as of 06:30 AEST, with total demand at 6,648 MW — a notable step down from the morning peak of 8,508 MW recorded around 17:45 AEST and the intraday high of $120/MWh at 17:30 AEST. Tracking across the past 24 hours, prices ranged from a low of $23.91/MWh in the early overnight trough through to those morning peak levels, placing the current $98.14/MWh in the elevated-but-stable band that has characterised the late evening. The generation mix at the most recent trading interval is dominated by black coal at 5,140 MW, followed by hydro at 970 MW, wind at 539 MW, gas OCGT at 11 MW, and battery at 5 MW. Solar output is effectively zero, consistent with the current overnight/pre-dawn period. Renewables are contributing 22.71% of supply, with carbon intensity sitting at 0.6798 tCO2/MWh — up from the overnight low of 0.429 tCO2/MWh recorded around 10:00 AEST when hydro and wind output pushed renewable penetration above 51%.

Today's weather profile is working against solar generation: cloud cover sits at 73% currently, and the daily outlook shows 89% average cloud cover with only marginal solar potential (avg 0.2) and low wind potential (avg 1.0). Expect carbon intensity to remain elevated through today relative to recent overnight lows, with renewables unlikely to replicate last night's 51% penetration peak. Heating demand is present at 3.5°C equivalent load given the 14.5°C ambient, which will sustain demand through the morning ramp. Predispatch forecasts for the 07:00 AEST half-hour (21:00 UTC) have been tracking upward in successive runs — the most recent forecast (issued 06:01 AEST) puts that interval at $113.58/MWh, up from $97.67/MWh in earlier forecasts — signalling the market expects a price step-up into the morning peak. The 07:30 and 08:00 AEST intervals are currently forecast in the $97–$108/MWh range, with later morning intervals from 16:30 AEST (06:30 UTC) onward forecast to ease toward $70–$79/MWh as demand retreats through the day.

The most operationally significant active notice for NSW is the Murraylink unplanned outage (Market Notice 144100, issued 01:48 AEST), which invoked constraint set I-ML_ZERO and zeroed the V-S-MNSP1 interconnector. A separate earlier notice (144097) had already flagged a Murraylink Redcliffs Convertor station short-notice outage from 20:45 AEST, constraining VIC1-NSW1 and V-S-MNSP1 flows. With Murraylink effectively offline, NSW loses a trading pathway to South Australia that can influence both energy and FCAS pricing — traders should monitor whether this outage extends into the morning peak. There is also a Directlink No.3 Leg outage (constraint N-MBTE_1 on N-Q-MNSP1) that remains active, limiting the NSW-
