Market Snapshot

South Australian prices fall as negative intervals persist across the NEM

Regional average prices ranged from $42.00/MWh in South Australia to $74.70/MWh in New South Wales. Tasmania saw the highest single interval price of $146.66/MWh, while South Australia reached a minimum of -$101.00/MWh. Negative pricing was also observed in Queensland and Victoria, though to a lesser extent than in the southern region.

Coal remained the primary generation source at 53.1%, supplemented by a 25.0% contribution from wind. Combined solar sources provided 11.3% of the mix, helping renewables reach an instantaneous peak of 60.7% at 14:20 AEST. Hydro and gas contributed 6.5% and 1.9% respectively.

Batteries discharged 16,129 MWh into the grid, representing 2.3% of the total generation mix. Total emissions reached 356,620 tonnes of CO2, a 3.3% increase compared to the same day last week. FCAS costs were concentrated in Tasmania, where Raise Regulation reached a peak price of $63.00/MWh.

Interconnector flows saw 40,881 MWh move from New South Wales to Queensland. Conversely, 15,158 MWh flowed from Victoria into New South Wales. Demand peaks occurred simultaneously at 18:35 AEST in both Queensland and South Australia.

Today · Forecasts indicate a peak price of $319.04/MWh in Queensland at 19:30 AEST and $145.00/MWh in South Australia at 18:30 AEST.

Why it matters · The daily average of $63.10/MWh sits 16.2% below the 7-day average, continuing a volatile trend where prices have fluctuated between $31.80/MWh and $121.60/MWh. This lower average was driven by the high frequency of negative intervals in South Australia despite a 3.3% rise in total emissions.
