2019-20 Integrated System Plan Consultation
AEMO is currently consulting 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).
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
AEMO has prepared this inaugural Integrated System Plan (ISP) for the National Electricity Market (NEM). The ISP was recommended by the Independent Review into the Future Security of the NEM (Finkel Review). Recommendation 5.1 from the Finkel Review stated:
“By mid-2018, the Australian Energy Market Operator, supported by transmission network service providers and relevant stakeholders, should develop an integrated grid plan to facilitate the efficient development and connection of renewable energy zones across the National Electricity Market”.
AEMO has called this an Integrated System Plan (ISP), rather than an integrated grid plan, to reflect that over time, the ISP will by necessity consider a wide spectrum of interconnected infrastructure and energy developments including transmission, generation, gas pipelines, and distributed energy resources. The 2018 ISP is not the end of the process, but rather the first of many steps, with updates in future years to reflect the dynamically changing nature of the power system and the need to continually innovate and evolve strategies for the future.
The first ISP delivers a strategic infrastructure development plan, based on sound engineering and economics, which can facilitate an orderly energy system transition under a range of scenarios.
As the ISP’s purpose and scope encompass those which would normally be covered in AEMO’s National Transmission Network Development Plan (NTNDP), the Australian Energy Regulator (AER) has permitted AEMO to defer the release of the 2017 NTNDP and integrate it into this ISP.
The interactive map complements the ISP. The map can be accessed through the following link: Interactive Map.
The ISP Database provides supporting modelling data and input assumptions.

Integrated System Plan Consultation
AEMO is consulting broadly and extensively at all stages during the development of the ISP. This consultation paper sets out AEMO’s approach to delivering the ISP and seeks feedback on specific questions, as well as any broader comments on its approaches and preliminary observations.
AEMO consulted on the development of the Integrated System Plan.
