Gas market reports and notices
Declared Wholesale Gas Market Reports
The DWGM Reports are published to inform market participants of events that have had an impact on the gas market under National Gas Rule (NGR) 351. For more information please contact GasMarket.Monitoring@aemo.com.au
Intervention Reports
AEMO intends to adopt the following approach to reporting on these events, wherever possible from 2018:
- Investigate and publish a report based on immediately available data within 10 business days of the relevant event.
- Where not all information necessary to complete the required assessment is available, that report will be flagged as preliminary, with a final report to be published once the additional information is received and analysed.
