Distribution loss factors methodology

The National Electricity Rules advise that distribution loss factors must be determined by a Distribution Network Service Provider for all connection points on its distribution network, either individually or collectively.

Distribution loss factors notionally describe the average energy losses for the financial year for electricity transmitted on a distribution network, between a distribution network connection point and a transmission network connection point, or virtual transmission node.

Our Distribution Loss Factors Methodology (PDF 710.5 kb) outlines the method we apply to the calculation of customer distribution loss factors and is published in accordance with the National Electricity Rules.
