On 8 December 2023, Energy Ministers agreed to progress Stage 2 of the reforms to the east coast gas system reliability and supply adequacy framework (RSA framework) through the Australian Energy Market Commission’s (AEMC) standard rule change request process.
The proposed reforms, which are the subject of four separate but interrelated rule change requests, are intended to build on and supplement those elements of the RSA framework that was implemented in May 2023 as part of Stage 1 of the RSA framework development. The four rule change requests are:
- the ECGS notice of closure of gas infrastructure rule change request.
- the Reliability Standard & Associated Settings rule change request.
- the Supplier of Last Resort (SoLR) Mechanism rule change request.
- the Projected Assessment of System Adequacy (PASA) rule change request.
On 11 September 2025, the AEMC completed its consultation on the ECGS notice of closure rule change request. AEMO is amending the GSOO Procedures in response to the Rule change. This consultation implements AEMO’s consultation on the GSOO Procedures.
