2022 Integrated System Plan (ISP)

Current Status

In October 2020, AEMO commenced work on the 2022 Integrated System Plan (ISP). As outlined in the 2022 ISP Timetable, the initial focus is to consult and agree with stakeholders on the inputs, assumptions and scenarios that AEMO proposes to use in its 2021-22 forecasting and planning activities, including the 2022 ISP. As part of the Inputs, Assumptions and Scenarios Report, AEMO has commenced consultation on the Draft Transmission Cost Report.

In addition, AEMO has commenced consultation to develop the ISP Methodologyin accordance with the Australian Energy Regulator’s (AER’s) Forecasting Best Practice Guidelines.

Consultation on these two foundational milestones will be completed prior to publishing the Draft 2022 ISP in December 2021.

Key milestones relating to the 2022 ISP are shown below.
