Regional Outlook — NSW1
The NSW spot price sits at $100.61/MWh as of 06:30 AEST, with total demand at 7,546 MW — up sharply from overnight troughs below 5,000 MW as the morning ramp progresses. This is consistent with the price trajectory over the past 24 hours, which bottomed out near $0.90/MWh in the early hours (07:00–08:00 AEST overnight) before climbing steeply through the morning peak, touching $120/MWh briefly around 17:10 AEST. The 24-hour price profile shows a clear overnight valley followed by sustained readings in the $77–$100/MWh band through the business day, with the current interval marking a fresh intraday high as demand continues to build through the morning peak window.
The generation mix is dominated by black coal at 5,430 MW, with hydro contributing 546 MW and wind at 139 MW. Solar output is modest at 43 MW — consistent with April solar angles and low overnight-to-early-morning irradiance. Gas CCGT and OCGT are both at zero dispatch. Renewable penetration sits at 11.83% at the latest interval, down from a daytime peak of around 20.4% recorded near 19:30 AEST during the prior afternoon when solar was more active. Carbon intensity is 0.7759 tCO2/MWh, broadly in line with the 24-hour range of 0.70–0.83 tCO2/MWh, with the lower end achieved during peak solar hours and the higher end during the pre-dawn period when hydro and wind were the only non-coal sources online.
Predispatch forecasts for the 07:00 AEST half-hour target are tightly clustered in the $91–$98/MWh range across multiple run times, with the most recent forecast (20:01 UTC, i.e. 06:01 AEST) at $94.61/MWh. This points to prices remaining elevated through the morning peak but not escalating dramatically from current levels — the $100/MWh print may soften slightly as demand growth moderates post-peak. Load window data indicates a strong price relief window opening from approximately 08:30 AEST (22:30 UTC) onwards, with forecast prices dropping to the $8–$20/MWh range and further into negative territory from 10:30–14:00 AEST as solar generation builds — signalling flexible load and battery charging opportunity through the midday period.
On market notices: AEMO issued a large volume of "Prices Subject to Review" notices under NER clause 3.9.2B for intervals spanning approximately 18:00 to 23:35 AEST on 27 April, covering potential manifestly incorrect inputs. Several of those intervals have since been confirmed unchanged. The most operationally significant active notice for today is a Forecast LOR1 in the SA region for 18:00–20:30 AEST this evening (notice 144006), though a subsequent cancellation notice (144007) indicates this condition has since been revoked as of 01:55 AEST. There are no active reserve or constraint notices directly affecting NSW at this time.
