On 10 December 2021, AEMO published the Draft 2022 Integrated System Plan (ISP), a copy of which is available here. The ISP is a biannual planning document that suggests a pathway for transmission development based on a range of different scenarios. In response to the Draft ISP, parties were invited to provide submissions to inform the final ISP, due to be released by AEMO on 30 June 2022.

AGL provided a response to the Draft ISP. A copy of that submission is available here.
