The National Electricity Market (NEM) continues to undergo an unprecedented and rapid transition, changing the way in which the power system will be operated. The transition also fundamentally affects future investment priorities. AEMO’s 2018 Integrated System Plan (ISP) articulated a whole-of-system development pathway, to design and execute the transition in a way that maximises benefits at lowest cost and risk to consumers. This ISP Insights paper is intended to:
Provide better understanding of proposed pumped hydro developments and their associated transmission infrastructure, based on updated data and improved modelling.
Deliver timely information to stakeholders to support action to increase the future resilience of the power system in the NEM, without waiting for the next ISP, which will be finalised next year.
