2026 Integrated System Plan (ISP)
AEMO’s Integrated System Plan (ISP) is a roadmap for the transition of the National Electricity Market (NEM) power system, with a clear plan for essential infrastructure that will meet future energy needs. The ISP’s optimal development path (ODP) sets out the needed generation, storage and network investments to transition to net zero by 2050 through current policy settings and deliver significant net market benefits for consumers.
AEMO is currently developing the 2026 ISP. The ISP Timetable is available below, followed by links to information about the ISP Consumer Panel and opportunities for engagement.
