However, the report identifies some inputs and assumptions that should be explained to further support and strengthen stakeholder understanding of key inputs and assumptions in the 2024 ISP. AEMO must provide further explanation on these issues as an addendum to the IASR and consult on these issues in the draft 2024 ISP.And the it points out the trainwrecks..
When compared with 2021 IASR scenarios,AEMO has not clearly explained why there is lessevidence of widespread electrification andtherefore how this slower investment inelectrification has been reflected in the updatedforecasts. We observe that since the 2023 IASRwas published that the Victorian Government hasannounced a ban on gas connections to newresidential and government buildings from 1January 2024 and expect the impact of this policywill be included in the draft ISP.....
However, there is noexample given for how electrification may affectshoulder periods including Autumn and Spring.We expect to AEMO explain why these periodsdo not need to be discussed.

Further, there is little detail discussing theassumptions regarding which power systemsecurity services will come online and when.Rather AEMO only states that they expect a mixof technologies to be delivered
