Matter under consultation

The National Electricity Rules (NER) require AEMO to calculate and publish, each year, inter-regional loss factor equations and intra-regional loss factors. AEMO has developed the Forward-looking Transmission Loss Factor (FLLF) methodology (often referred to as the Marginal Loss Factor (MLF) methodology) to set out the process by which these factors are determined. Within the scope permitted by the NER, AEMO can amend the FLLF methodology by following the standard rules consultation procedure described in NER 8.9.2.
