2020 Integrated System Plan (ISP)

Page contents

Current status and progress updates

The 2020 ISP is currently under development, with a detailed timeline shown below. The consultation on scenarios, inputs and assumptions was completed in August 2019. The Draft 2020 ISP has now been released, and consultation on this document and on non-network options closed on 21 February 2020 and 13 March 2020 respectively – see details below.

AEMO has completed the initial review of submissions to both the Draft 2020 ISP and Non-network consultations, outlining some of the key changes that will be made to the ISP inputs and assumptions as a result of the consultation feedback in the April progress update. The June progress update includes an explanation of the development stages of Renewable Energy Zones (REZs):

Draft 2020 ISP

The Draft ISP sets out the optimal development path for Australia’s energy future. It aims to ensure Australians enjoy affordable, secure and reliable energy in future and for generations to come. 

The draft, for consultation, builds on the analysis of the inaugural 2018 ISP and follows considerable industry engagement on the design of forecasting and planning scenarios and sensitivities. 

Consultation on the Draft 2020 ISP

AEMO is developing and consulting on the Draft ISP at the same time as the Energy Security Board (ESB) is consulting on the Draft ISP Rules to make the ISP ‘actionable’. The intention is that the 2020 ISP, once finalised, will be deemed to have been prepared, consulted and published in accordance with the new ISP Rules on the date when those rules start. 

In addition, actionable ISP projects will be transitioned to the new regulatory framework, including those that commenced their RIT-T process under the current framework.  AEMO will therefore consult in accordance with the Draft ISP Rules requirements. To aid clarity, the following table summarises the various parallel consultations that occurred concurrently over the period December 2019 to March 2020.

Concurrent consultations December 2019 to March 2020

2019 scenarios, inputs, assumptions and methodologies

AEMO strives to ensure its planning and forecasting publications are of highest quality, with data that is fit for purpose and industry-reviewed, and processes that are transparent. To build confidence in the forecasts, and help decision makers understand the outcomes, AEMO consults on and publishes its scenarios, inputs, assumptions and methodologies. 

If necessary, confidential information is withheld from public release, but incorporated in the modelling conducted to deliver assessments that are as accurate as possible. 

Consultation is now complete on the scenarios, inputs, assumptions and methodologies to be applied to the 2020 ISP, as completed by the 2019 Planning and Forecasting Consultation on scenarios, inputs and assumptions.

These documents contain key information on conclusion of this consultation:

AEMO’s collection of scenarios, inputs, assumptions and methodologies for use in Forecasting and Planning activities are available at the following link, along with a listing of all of the engagement activities that were carried out in 2019 during the inputs and assumptions consultation, and associated materials

2020 ISP Database

Specific assumptions, methods and supporting materials are added to the ISP Database:

Supporting ISP Insights

An Insights paper was released in July 2019, providing new perspectives and deeper analysis on the important role pumped hydro energy storage (PHES) and strategic transmission developments can play in lowering costs to consumers and increasing the resilience of the National Electricity Market (NEM).
