The AER has today published the Australian Energy Market Operator’s (AEMO) 2025 Forecasting Best Practice (FBG) Compliance Report and our assessment of that report.
AEMO is required to demonstrate in writing it has complied with all requirements and considerations as per the option expressed in section 5.2 of our Forecasting Best Practice guidelines.
The compliance report enables AEMO to self-identify whether it has:
- complied with applicable requirements
- had regard to applicable considerations (including the reasons for the weight it has attached to each consideration)
- resolved key issues raised by the AER through the issues register
- identified any breaches of the FBP guidelines and provided explanation for any breach.
Our assessment focused on the activities related to the development of the 2026 Integrated System Plan and forecasting activities.
We communicated our assessment of the 2025 FBG Compliance Report in a letter to AEMO sent on 14 November 2025.
