Implementation of extension of the DWGM Dandenong LNG interim arrangements

Timeline

On 3 April 2025, the Australian Energy Market Commission (AEMC) received a rule change request from the Hon. Lily D'Ambrosio, Minister for Energy and Resources, Climate Action, and State Electricity Commission, to amend the National Gas Rules. The rule change request proposed a short-term three year extension of the 2022 DWGM Dandenong LNG (DLNG) interim arrangements and a range of measures to improve transparency and oversight of the Dandenong liquefaction facility.  

On 1 May 2025, the AEMC initiated consultation on the extension of the DWGM Dandenong LNG interim arrangements rule change request. The AEMC published its final decision on this Rule change on 30 October 2025. This Rule change:

1. Extended the DLNG interim arrangements until 31 December 2029.
2. Requires the declared LNG supplier for the liquefaction facility supplying the DLNG facility to comply with Rule 324 (Participant disclosure obligations) and 326 (Maintenance planning) requirements.
3. Requires the declared LNG supplier to apply to AEMO to register as the BB reporting entity for its liquefaction facility and allows that liquefaction facility supplying the DLNG facility to be registered on the Gas Bulletin Board as either a BB Storage Facility or a BB Liquefaction Facility.

This expedited consultation is to implement the changes required to AEMO’s Procedures to align with the amended Rule requirements.
