5MS and GS industry readiness information

This page explains where to find detailed information on implementing 5MS and GS. 

The 5MS and GS Market Readiness Strategy is the overarching plan to guide AEMO and NEM participants’ readiness activities. It covers both AEMO’s and NEM participants’ operational preparedness for 5MS and GS and sets out the approach for:

  • Managing,
  • Coordinating,
  • Informing,
  • Monitoring, and
  • Reporting.

The Market Readiness Strategy is supported by a series of documents. These strategies and plans each cover a specific area of readiness and provide more detail on coordinated 5MS and GS implementation by the industry.  The diagram shows the relationships between the documents and the table describes the purpose of each document. 

Detailed timing for the development of the transition, cutover and contingency plans will be included on this page as developed by the RWG and Focus Groups.
