Queensland price volatility contrasts with steady demand across the National Electricity Market
Regional price outcomes varied significantly as Queensland averaged $48.50/MWh despite frequent negative intervals, while South Australia saw the highest peak price of $260.00/MWh. New South Wales and Victoria maintained mid-range averages of $70.50/MWh and $58.50/MWh respectively, with no recorded cap or negative intervals in those regions.
Coal remained the primary generation source at 55.6%, supported by a combined solar contribution of 16% and wind at 15.8%. Renewables achieved an instantaneous peak of 65.7% at midday, while hydro generation provided a steady 8.2% of the total energy supply.
Battery storage systems discharged 8,387 MWh into the grid, resulting in a net consumption of 9,637 MWh for the trading day. Total system emissions rose by 5.6% compared to the same day last week, reaching 355,148 tonnes of CO2.
FCAS costs were led by Raise Regulation services in Tasmania at $34,970, while South Australia saw the highest individual service price of $49.00/MWh. Interconnector flows were most active between New South Wales and Queensland, with a net export of 44,498 MWh from the northern region.
Today · Pre-dispatch forecasts indicate a price peak of $319.04/MWh in Queensland at 19:30, with other regions expected to remain below $150.00/MWh.
Why it matters · The daily average of $66.50/MWh sits 3% below the 7-day average, continuing a volatile trend where prices have fluctuated between $37.00/MWh and $105.90/MWh. This session is notable for the divergence between Queensland's 100 negative intervals and the 5.6% rise in total emissions, indicating a highly stratified generation mix.
