Update to the 2020 ISP
Following completion of the Regulatory Investment Test for Transmission (RIT-T), a Transmission Network Service Provider (TNSP) may seek written confirmation from AEMO that the preferred option from the RIT-T remains aligned with the optimal development path in the most recent ISP. This process is referred to as the feedback loop.
In accordance with the National Electricity Rules, AEMO identified that an ISP update was necessary to allow material changes identified in the 2021 Inputs, Assumptions and Scenario Report (IASR) to be considered by AEMO when assessing actionable ISP projects in the feedback loop.
2020 ISP
The 2020 ISP provides an actionable roadmap for eastern Australia’s power system. The ISP draws on extensive stakeholder engagement and internal and external industry and power system expertise to develop a blueprint that maximises consumer benefits through a transition period of great complexity and uncertainty.
The ISP is a whole-of-system plan that efficiently achieves power system needs through that transformational period, in the long-term interests of the consumers of electricity. It serves the regulatory purpose of identifying actionable and future ISP projects, as well as the broader purposes of informing market participants, investors, policy decision makers and consumers.
The ISP was released on 30 July 2020 and can be downloaded using the links below.

Stakeholder Consultation
For the 2020 ISP, AEMO has consulted extensively with industry, academia, government, developers and consumer representatives. After two rounds of consultation, one before and one after the publication of the Draft 2020 ISP in December 2019, improvements have been made to the 2018 ISP.
Consultation on non-network options
Central-West Orana REZ Transmission Link Non-Network Consultation
Following publication of the 2020 ISP, AEMO consulted on non-network options for the Central-West Orana REZ Transmission Link. AEMO received several confidential submissions to address the identified need.
The final report was published on 14 May 2021. This report concluded that all the submitted non-network options are reasonably likely to assist with meeting the identified need.
