2020 Integrated System Plan (ISP)

Current status

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 opened on 12th December 2019, along with a separate call for submissions on non-network options – see details below.

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 are occurring concurrently over the period December 2019 to March 2020, including dates and submission details.

Concurrent consultations December 2019 to March 2020

The Draft ISP Rules require AEMO to publish a call for non-network options for actionable ISP projects. The purpose of this draft Rule is to ensure that proponents of non-network options have the opportunity to put forward their options for consideration. This notice applies to both the QNI Medium and VNI West actionable ISP projects:

Submission on non-network options and other matters are welcome until Friday 13 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

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).
