Monitoring performance and analysing trends
The AER monitors the performance of wholesale electricity and gas markets and publishes data in reports such as the State of the energy market and the Wholesale markets quarterly.
On this page you can view and download individual charts and data tables from our most recent market performance reports.
Highlights include:
Electricity Q3 2024
- Q3 trends for the National Electricity Market will be updated shortly.
Gas Q3 2024
- Gas market prices decreased from the previous quarter after stabilising from mid-August, influenced by fewer peak demand days over Q3.
- In July, strong gas flows south from Queensland provided increased supply to meet higher southern demand.
- High South West Pipeline flows supplying gas from underground storage in Victoria helped meet demand and offset lower Longford Production.
- From mid-August, demand and prices decreased following milder weather conditions, lower mainland GPG and increased hydro generation in Tasmania.
- The reduced demand levels and more stable output from Longford in August saw Iona storage levels replenished, leading to AEMO revoking a potential threat to system security notice on 23 August.
- Day ahead auction activity remained strong, hitting a record level of transportation capacity won for Q3.
- Trade at Wallumbilla hub reached a record level with more than 12.3 PJ of gas traded over the quarter.
- The higher Wallumbilla trade led to a record churn rate of over 26%, the strongest amount of trades for delivery in Q3 as a proportion of physical flows yet.
