Integrated System Plan
The Integrated System Plan (ISP) is a whole-of-system plan that provides an integrated roadmap for the efficient development of the NEM over the next 20 years and beyond. Its primary objective is to maximise value to end consumers by designing the lowest cost, secure and reliable energy system capable of meeting any emissions trajectory determined by policy makers at an acceptable level of risk. It fully utilises the opportunities provided from existing technologies and anticipated innovations in Distributed Energy Resources (DER), large-scale generation, networks and coupled sectors such as gas and transport. AEMO prepared the inaugural Integrated System Plan (ISP) for the National Electricity Market (NEM) in 2018, and it will be updated every two years.
2019-20 Integrated System Plan (in Development)
AEMO has now completed its consultation on the scenarios, inputs, assumptions, methodology, timeline and consultation process for a collection of Forecasting and Planning publications, including the 2019-20 Integrated System Plan (ISP). The following links provide access to details on the 2019-20 ISP (in development), and the scenarios, inputs and assumptions to be used in 2019-20 Planning and Forecasting publications.

- 2019 Forecasting and Planning Scenarios, Inputs and Assumptions Report (2.8 MB, pdf)
- 2019 Input and Assumptions workbook (24.7 MB, xlsx)
The key documents that complete the Consultation are:

An Insights paper following the 2018 Integrated System Plan
AEMO has released an Insights paper that provides 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).
Independent, third party analysis of 2018 Integrated System Plan
AEMO has published two independent, supplementary analysis reports that further investigate two core components of the 2018 ISP.
Developed by Aurora Energy Research (Aurora), Report 1 analyses the potential reduction in power bills the implementation of the ISP could provide to Australian energy consumers through increases in competition and market efficiency through additional interconnection investment. Report 2 provides independent economic analysis on whether AEMO’s coal closure timeline (based on either advice of closure or expected end of technical life in the ISP plan period) requires adjustment because of changing earnings in an evolving market environment.
AEMO recognises the findings of Aurora’s independent study, however confirms these assumptions do not necessarily represent the view of the market operator.

2018 Integrated System Plan
The first ISP delivered a strategic infrastructure development plan, based on sound engineering and economics, which can facilitate an orderly energy system transition under a range of scenarios:
