ISP Methodology

AEMO commenced a consultation on the ISP Methodology on 31 March 2023. This consultation requested stakeholder input on eight proposed updates to the ISP Methodology.

AEMO followed the requirements of the Australian Energy Regulator’s Forecasting Best Practice Guidelines and Cost Benefit Analysis Guidelines in developing the ISP Methodology. This included providing a transparent process, supporting and working with stakeholders in their understanding of AEMO’s analysis, methodologies and data, and providing additional information to complement the formal documentation.

There was one round of formal stakeholder consultation, with workshops, meetings and briefings as required. The process concluded on 1 May 2023.
