Procedure change proposal

Electricity System and Market Rules – Clause 2.10

Date of Notice: 11 March 2026

Matter under consultation

AEMO commenced the Procedure Change Process to propose amendments to the WEM Procedure: Certification of Reserve Capacity to provide additional guidance to Market Participants that may be insolvent or insolvent under administration, with respect to information that is required to be provided under clause 4.10.1(g)(ii). In doing so, it closes a potential gap in the application process where a potential Reserve Capacity provider is insolvent or insolvent under administration.

These changes are relevant for Market Participants who are considered ‘insolvent’ under the ESM Rules, specifically with respect to the meaning of the term in clause 9.19.2.

For Market Participants that are insolvent or insolvent under administration, AEMO requires additional information to support AEMO in forming a reasonable expectation of whether the Market Participant’s Facility will be able to meet its availability obligations for the relevant Capacity Year. A new section under Paragraph 3 and a new definition have been drafted to give effect to the proposed amendments.

The proposed changes are consistent with the information that a Market Participant may be required to provide under clause 4.10.1(g)(ii), and align with the existing head of power under clause 4.9.10(a).

On 6 February 2025 the State Electricity Objective (SEO) replaced the Wholesale Market Objectives under section 3A of the Electricity Industry Act 2004.  Following an assessment, AEMO considers the Procedure is consistent with the SEO.

Invitation to make submissions

AEMO invited written submissions on this Procedure Change Proposal, including any alternative or additional proposals may improve the Procedure or better meet the State Electricity Objective under section 3A of the Electricity Industry Act 2004.

AEMO requested that respondents identify any parts of their submission that they wished to remain confidential, explaining why. AEMO advises that it may still publish that information if it does not consider it to be confidential, but will consult with the respondent before doing so.

When making a claim for confidentiality, AEMO encouraged respondents to familiarise themselves with Chapter 10 of the Electricity System and Market Rules (ESM Rules), which imposes obligations in respect to the release of documents.
