On 26 November 2021, AEMO advised the May 2022 Readiness Working Group (RWG) of its intent to delay the implementation date of a number of the MSDR Changes to 7 November 2022. AEMO presented and discussed the proposed implementation delay of these MSDR Changes at the Electricity Retail Consultative Forum (ERCF) – including in the context of the plans to consult with industry on the following Procedures and Guides:

  • MSATS Procedures CATS Procedures
  • MSATS Procedures WIGS Procedures
  • Standing Data for MSATS
  • Metrology Procedure Part A
  • Retail Electricity Market Procedures – Glossary and Framework version

AEMO considers that delivering these MSDR Changes by 1 May 2022 is high risk, due to the complexity of solution architecture, along with resource and environment constraints.

Submissions for this stage of consultation close on 17 December 2021. Please send your submissions through to

MSDR Phase 1 – 1 May 2022

MSDR Phase 2 – 7 November 2022
