Marginal Loss Factor Framework Review

Between July and December 2024, AEMO conducted a round of formal consultation on its Methodology for the Calculation and Application of Forward-Looking Loss Factors (FLLFs). In parallel to this, it compiled a ‘discussion points register’, listing Marginal Loss Factor (MLF) reform ideas that sat outside the scope of the current National Electricity Rules (NER).

Following the conclusion of the methodology consultation, AEMO held two ‘discussion forum workshops’ to refine and develop these reform ideas. AEMO has commenced a research project on the options most preferred by stakeholders. We intend to share a report in the second half of 2025 with the findings of our research and consult with stakeholders on these findings.
