Market Snapshot

Regional price divergence as New South Wales average reaches 117 dollars

Daily average prices ranged from a low of 58.10 dollars in Tasmania to a high of 117.30 dollars in New South Wales. South Australia and Victoria both experienced brief negative pricing intervals, with South Australia recording the highest single price peak of 317.70 dollars.

System demand was highest in New South Wales, peaking at 11056 megawatts at 17:55. Most regions saw their maximum load during the early evening peak, with Queensland reaching 7977 megawatts and Victoria hitting 7793 megawatts.

Renewable generation reached an instantaneous peak of 48.6 percent at 11:25. Wind contributed 17.8 percent to the daily mix, while utility and rooftop solar combined for 8.5 percent. Coal remained the primary fuel source at 54.7 percent.

Batteries discharged 11149 megawatt hours throughout the day, while total emissions fell 4.2 percent compared to the same day last week. FCAS costs were highest in the Raise Regulation service, totaling 45700 dollars with peak pricing occurring in New South Wales.

Today · Forward projections indicate a Queensland price peak of 319.04 dollars at 19:30, while other regional peaks remain below 150.00 dollars.

Why it matters · The daily average of 105.90 dollars sits 9 percent below the 7-day average, continuing a volatile trend following a mid-week peak of 167.40 dollars. This price level occurred despite a relatively low 37.1 percent renewable share and significant battery discharge, indicating tight correlation between fossil fuel generation and evening demand peaks.
