2026 ISP Stakeholder Engagement

Our engagement goal for the 2026 ISP is to provide interested stakeholders with appropriate time and opportunity to provide meaningful input into our planning. We want all interested stakeholders to get involved and shape our planning for the efficient development of the energy system, for the benefit of all Australians, as we work to achieve a net-zero future.

AEMO has published the 2026 ISP Stakeholder Engagement Plan below as an initial proposal and welcomes feedback from interested stakeholders on our approach any time during the two-year engagement program. AEMO will periodically review its engagement approach and apply any learnings throughout the development of the 2026 ISP and future engagement processes.

For more information about AEMO’s engagement approach or the 2026 ISP engagement program, see the 2026 ISP Stakeholder Engagement Plan.
