The Integrated System Plan (ISP) is a whole-of-system plan that provides an integrated roadmap for the efficient development of the National Electricity Market (NEM) over the next 20 years and beyond. This consultation relates to the methodologies that AEMO proposes to use in the 2022 ISP. 

AEMO has prepared an Issues Paper that provides:

  • An overview of existing methodologies.
  • Areas where AEMO is looking to enhance existing methodologies or introduce new methodologies.

Invitation for submissions 

All stakeholders are invited to provide a written submission to the questions outlined in this Issues Paper, and on any other matter related to the methodologies to be used in the preparation of the 2022 ISP. Submissions need not address every question posed and are not limited to the specific consultation questions contained in each chapter.

Submissions should be sent via email to and are required to be submitted by Monday 1 March 2021. All submissions should be provided in PDF format. Please identify any parts of your submission that you wish to remain confidential, and explain why.

AEMO requests that, where possible, submissions should provide evidence and information to support any views or claims that are put forward.

Consultation process 

The National Electricity Rules require AEMO to develop, consult and publish the ISP Methodology in accordance with the Australian Energy Regulator’s (AER’s) Forecasting Best Practice Guidelines. 

In developing the ISP Methodology, AEMO aims to seek stakeholder input and feedback through workshops as well as written submissions. The below figure provides further detail on the key dates of this formal consultation.
